The Propane Refrigerator vs. Solar Fridges

Posted on

When choosing an off grid refrigerator, there are many things to consider. The biggest decision being; should your power source be propane or solar?

To ultimately decide on either propane or solar, you may want to answer these questions first:

  • Which is less problematic?
  • How long do they last?
  • Which is most efficient?
  • And which is most cost effective overall?

With these questions in the forefront of our minds, we aim to answer them in this article. There is a lot to unpack, so let’s get started.

So if you happen to live off-grid year round or even if you are only off-grid occasionally throughout the year with perhaps a summer cabin, fishing or hunting camp. You definitely need a refrigerator for your cold food storage. Hauling ice is a hassle, not to mention it is expensive! But what direction do you go? Should you buy a propane refrigerator or a solar one? This is a common question folks have. Our team has spent many years selling both types of refrigerators, and we’ve collected data from both sides of the isle.  Our opinion is this: the propane refrigerator is much more straightforward to use, and it is easy to maintain. Additional benefits of propane refrigeration are that it is much more durable, as well as overall a propane unit is more efficient, and cost effective than solar. Hopefully, this article will prove itself useful to you as you ponder which direction to go.

Simplicity

Propane refrigerators are simple.  They are decidedly straightforward in their operation.  A gas fridge has a cooling unit operated by a pilot light.  In simple terms, this cooling unit and flame make up the whole system! The cooling unit continues to cycle the cooling vapors using the pilot light.  There are very few components to ever malfunction. Plus, propane units do not require sunlight! Generally, the service on a propane refrigerator involves cleaning the burner box…which is easy!  The setup is simple too; just attach your gas line onto the 3/8” male flare screw fitting on the back of the fridge, light the pilot light and you’re good to go!

In contrast, solar refrigerators use a compressor system made up of many different components and electrical pieces.  Solar refrigerators require compressors, refrigerant solution, solar panels, batteries, controllers and other electrical wires and components to make the refrigerator run properly–not to mention the requirement for sunlight…and lots of it!  The point here is that within an electrical refrigerator (which is essentially what a solar refrigerator is) there are many parts and pieces that could wear out, go bad or malfunction leaving your refrigerator totally useless…plus, you can’t control the sun and with solar you need a steady supply of sunshine!

Longevity

Next, propane fridges just last longer than solar fridges. Today’s EZ Freeze propane refrigerator is lasting upwards of 20 to 30 years.  Occasionally, a thermocouple or a thermostat needs to be replaced but even if you have no technical skills, you will be able to change them out yourself! Plus, EZ Freeze fridges come with a maintenance video as well. Generally, all you need is a wrench or a screwdriver to change out these parts. This proves especially useful when living off-grid, where tools and maintenance services are scarce. Plus, the parts are very easy to get your hands on because they are made in the USA.

Solar refrigerators last as long as the “normal” electric refrigerator you may have in your “on-grid” home.  Some can last more than 10 years, BUT when they do stop working or malfunction, getting them fixed is very involved. You may not find the parts you need and it may require taking the fridge to a service repair establishment.  The last thing you want to do while living off the grid is to spend your time and energy fixing and troubleshooting appliances. Your valuable time will be better spent tending to the other chores and necessities that come with living off-grid.

Efficiency

Efficiency is also a consideration when deciding between propane and solar.  Solar systems are expensive. The panels alone cost $10,000 to $20,000 and up from there. This doesn’t even include the battery!  Batteries can cost $5,000 to $7,000. Also, it is recommended that you have a backup generator (thousands of dollars) for those gloomy months when the sun is not shining in order to charge your batteries.  Let’s remember, the generator requires fuel and adds additional variables that can malfunction or fail.

Cost-effectiveness

So let’s break this down a bit:

Let’s say a solar system with panels, batteries and a backup generator costs a very conservative $20,000. Your fridge works off of this solar system at no monthly cost.

An all off-grid home, run with propane, has a propane refrigerator, propane stove and gas lights. The fridge, on average, will consume 1.5 gallons of propane a week.  That’s roughly 80 gallons of propane a year to run the fridge. Propane at an average of $2.00 a gallon will cost you $160 a year. Powering your lights and oven via propane will cost a little bit more.  If we tripled this cost to include propane lights and an oven/range, costs would be roughly $480 a year. That means it would take 42 years to make up for the cost of a $20,000 solar system. This does NOT factor in the fuel for the generator, or new batteries every 5 years, nor the maintenance expenses for the solar system.  As you can see the cost difference is too significant to argue when contemplating the two types of off-grid energy.

The Propane / Solar Synergy

Let’s not throw solar out the window all together.   Solar power as a whole, is a wonderful option and provides you with power needed to run other useful devices (i.e. lights, computer, cell phone).  If you do install a solar system, we want to help your solar system run as efficiently and for as long as possible. How do we do this? By removing those appliances that put heavy strain on your solar batteries. This simply allows for your other important items in your home, like the television, dishwasher and music player, to continue to work.  So, the best way to help your solar system run more efficiently is to remove heavy power consuming appliances from the solar grid entirely. Using a propane refrigerator and a propane stove will aid in this effort tremendously.

Choose a long established company

Now that we have determined how easy set up and maintenance of a propane fridge is, along with identifying the considerable low cost of running it, and additionally its longevity and power saving ability; let’s discuss another trend we have noticed: solar refrigerator companies seem to come and go.  The life span of these companies seem to be short. Which can certainly make finding parts and service locations very difficult. Please don’t misunderstand, this is not the case with all solar refrigerator manufacturers – even some propane refrigerator companies have left the market. However, as a whole, the propane refrigerator manufacturers stand the test of time.  

In the early to mid-1900’s Servel was the biggest propane refrigerator manufacturer.  Their units can still be found working in homes all over the world today! Since propane refrigerators were first on the market in the 1930’s, the science of the absorption cooling unit has proven its reliability through the test of time.  Whether you use natural gas or propane – the necessary combustion for the cooling unit has proven to work seamlessly over the years in creating the energy needed to heat the cooling unit solution. Our new units such as the EZ-Freeze propane refrigerator not only use the same technology and have the same longevity, but run on half of the propane of those refrigerators of old.  EZ-Freeze refrigerators only burn, on average, 1.5 gallons a week, per year.

EZ Freeze fridges are extensively tested in hot rooms, under extreme heat and humidity, which the solar refrigerators would not be able to keep up with.  The EZ Freeze brand propane fridges are safe, durable, and can be transported laying down; on their left side! You can’t do that with your solar fridge, as that is too dangerous!

Warranty

We also take pride in our 7 year warranty on the cooling unit, which is unheard of in the industry and this duration of warranty remains unmatched.  Not only is the warranty far superior to other propane manufacturers but EZ Freeze ranks #1 for any refrigerator, including solar.

Final Words

In conclusion, a well-made propane refrigerator from EZ Freeze will not only last you upwards of 20 to 30 years but it will save you time, money and is virtually hassle free. Our experience in the off-grid industry has taught us that solar power is useful and can provide power where there are no other options but when considering your two major appliances: the refrigerator and the stove, propane generated power is hands down the wiser investment.

How to set up your new gas refrigerator for proper operation

Posted on
Setting propane/gas pressure

It is very important that the gas pressure be set correctly. Too high or too low of gas pressure may lead to poor performance or permanent damage to your gas refrigerator. Proper gas pressure for a LPG propane system is 11 inches of water column. Your gas supplier will test and set the correct pressure for you. It is possible to do it yourself. Check out our “How to test gas pressure” page.

Burping the Propane Gas Refrigerator or Natural Gas Refrigerator
If your new Diamond gas refrigeratorsEZ Freeze gas refrigerators, or most other gas refrigerators, has been laid down during shipping or the unit is not cooling correctly within the first day or two of operation, it is possible that the unit may need to be burped. This process releases an air lock and allows the chemicals to return to the proper levels within the ammonia absorption unit. The process varies depending on the brand of gas refrigerator you own. For most models, turn the unit off and let the unit cool. Disconnect the gas supply line. Carefully rotate the unit upside down so it stands on it’s top. Rotate the gas refrigerator from side to side not front to back. Let the unit sit in this position for 15 minutes. Rotate back to it’s upright position standing on the legs. Let the unit sit in this position for another 15 minutes before lighting. Reconnect the gas supply and test for leaks.

Burping for Danby / Consul propane refrigerator models, turn the unit off and let the unit cool. Disconnect the gas supply line. Carefully rotate the unit counter clockwise to it’s left side. Let the unit sit in this position for 15 to 20 minutes. Rotate the unit counter clockwise upside down so it stands on it’s top. Let the unit sit in this position for 15 to 20 minutes. Rotate the unit counter clockwise to it’s right side. Let the unit sit in this position for 15 to 20 minutes. Rotate counter clockwise back to it’s upright position standing on the legs.

Tips for operating your Gas Refrigerator or Gas Freezer
Once the gas fridge / freezer is operating, let it chill down for approximately 12 hours before loading with food. You will notice the freezer will chill first. When the freezer portion is significantly chilled down, then the fridge section will start to get cold. This is the nature of the gravity operation built into the system. The refrigerator section is the first to be effected by any change to the thermostat, ambient air temperature, humidity, or change of door opening cycles. Load warm or room temperature foods in smaller portions a couple hours apart. Let the unit stabilize for a few days prior to making adjustments to the thermostat. Check the refrigerator compartment temperature first thing in the morning to get an accurate reading of the thermostat setting. We suggest to use an external thermometer to monitor the temperatures. Do not overload the unit with room temperature liquids such as large jugs of water. Load the freezer with Ice trays or objects to be frozen prior to bed time. This way the unit will have all night to recover. Aluminum Ice Cube Trays make ice much faster than plastic trays.

Be sure the gas fridge is level in both directions since the absorption system works from gravity, it is vital to the proper flow rate that the unit is level.

Be sure the gas refrigerator has proper ventilation an all sides. Most manufacturers will have recommendations within the owners manual. Minimums are usually 2″ left and right sides and 8″ above with 2″ at rear. Intake and exhaust ventilation is also recommended. Always turn the gas valve on slowly to protect the regulator and/or thermostat from a surge of pressure. Test for leaks with a solution of soapy water and brush around all gas connections before lighting the gas refrigerator.

EZ Freeze Gas Refrigerator Controls – Lighting Instructions

Posted on

The controls of the EZ Freeze propane refrigerator are located on the front of the unit at the bottom. All are hidden by the door or a removable panel. The controls include the Thermostat Control (shown as “Temp” within the gas refrigerator parts image below) which controls the temperature of both the refrigerator and freezer compartment. It adjusts the amount of refrigerant running through the system by controlling the high and low flame of the burner. The refrigerant of the absorption system is an ammonia and water solution that flows via gravity from the top of the freezer to the refrigerator section below and absorbing all the hot air. The higher the temperature control is set the more the flame will stay on high and produce more refrigerant, therefore making the interior colder.

The Gas Safety Shut-Off Valve on the EZ Freeze propane refrigerator (shown as “Gas” in the image) is magnetically-controlled by an electromagnet that is feed millivolts via the thermocouple. The thermocouple is heated by the flame and produces the small amount of electricity to power the magnet. If the flame is extinguished and the thermocouple does not sense heat, then the electromagnet will release and shut-off the gas supply. This prevents any unburned gas from escaping into the room.

The Piezo Igniter of the EZ Freeze Propane Refrigerator (shown as “Spark” in the image) is a self-powered, non-electric spark generator. It’s very similar to what propane BBQ’s use. By pushing this button, the Piezo Igniter will produce a spark to light the flame.

 

Lighting An EZ Freeze Gas Refrigerator

The First Time After the set-up of the unit is complete, use the following procedure to light the burner. First time lighting may take longer than usual due to the air that may be in the gas lines.

Turn on the gas valve at the rear of the gas refrigerator

To start the gas refrigerator, turn the thermostat knob “Temp” (Thermostat) to the #2 setting

Push and hold “Gas” (Gas Safety Valve) button, and then…

Press the “Spark ” (Piezo Igniter) button continuously 5 to 10 times to light burner. Confirm the flame is lit by viewing through the flame “Viewer”. It should be possible to hear a slight turbulent noise from the flame. If the burner is lit, continue holding the “Gas ” button for 5-15 seconds. Release the “Gas” button and confirm the burner is still lit. If the burner does not light, repeat steps 1 through 4.

We recommend that owners take a good look at the flame upon initial start up and note its size and color for future reference. It is good practice to visually check the flame for this size and color upon every start up.

Hand Lighting….

If for some reason the unit will not light with the piezo ignition or the igniter is failing to spark, it is possible to hand light the burner. This usually requires two people. Simply use the above procedure and replace “Spark ” Button with a person at the burner with a lighter.

This type of refrigerator uses manual operation. Setting the temperature information is here and the manual defrosting information is here.

Peerless Gas Off Grid Stove/Range – Questions and Answers

There are many things to consider when living without power.  What kind of stove/oven/range/cooktop to purchase is definitely one to consider before making a large investment. We’ve answered some common questions below about our Peerless Premier ranges.  Peerless premier propane battery spark ranges are the best option in off-grid living.

Q. Do the Peerless Premier Ranges operate from Propane (LPG) or Natural Gas?

A. All Peerless Premier Ranges are shipped to operate from Natural gas. All the units come with the instructions and parts to convert to Propane (LPG) gas. This is done during the installation process and is very easy.

Q. What type of ignition should I use when l don’t have power?Peerless Gas Range FAQ

A. Battery spark, electronic, gas pilot and glow bar ignition are all options when purchasing a stove or range.  It is important to know what type will work best when living off the grid.  Many people do not realize that a typical big name gas range purchased at a big box store still needs electricity to function. It will draw electricity to ignite the burners and will draw large amounts of electricity to heat the oven. Below is helpful information to understand the difference between the ignition types.

Q. What is Battery Spark Ignition?

A.  Battery Spark Ignition is the newest generation of off-grid ignition for ranges. Battery spark ignition is replacing gas pilot ignition. This ignition requires 8 AA batteries to power an electronic sparker on the range top as well as in the oven burner. This ignition can also be lit with a match ion the range top burners as well as in the oven in case batteries are not available or out of juice.  The best stove for off grid use is a propane battery spark ignition stove. Peerless premier offers off grid stoves, ovens and ranges that use propane with battery spark ignition.

Q. What is Electronic Ignition?

Peerless premier offers ranges in electronic ignition. Electronic Ignition is a very low wattage draw only during the spark phase of the range top burners or oven burner. This system works great for solar systems due to the low wattage draw. The Electronic Ignition type burners can also be lit with a match in the case that no electricity is available. Simply turn the burner to low and light The oven can be lit the same way and will operate normally through the entire cooking process until it is turned off.

Q. What is Gas Pilot ignition?

A. Electricity is not needed in this system. Gas Pilot Ignition is the trusty standard with a continuously burning pilot flame.

Q. What is Glow Bar Ignition?

A. Glow Bar Ignition is used by most brand name range manufacturers to ignite the oven during the cooking process. The glow bar draws a very high current to ignite the burner which puts a large load on solar systems. This lighting process repeats itself many times during one cooking cycle to control the heat range of the set temperature in the oven.  The oven is useless without electricity, since the glow bar cannot be lit with a match.  A glow bar ignition is not a good option when living off the grid.

EZ Freeze Gas Refrigerator Parts – Orifice Information

Posted on

Info on the EZ Freeze Orifice

The gas orifice is a very important part of any gas fridge.  EZ Freeze propane refrigerators all include a very precise orifice in the burner system that is unmatched in the industry. The Orifice includes a ruby gemstone tip, all brass construction, internal filter and pressure test port.

EZ Freeze Propane Refrigerator Parts - Gas orifice information for gas fridges from Warehouse Appliance - the off-grid appliance experts!

– Ruby Gemstone Tip –
EZ Freeze has these orifices manufactured specifically for a propane  refrigerator. The brass body of the orifice is bored out to accept a very precise ruby gemstone that has been laser-cut to the specific size. This process ensures that each orifice is virtually same size with the proper BTU output.

– Internal Filter –
Any slight change in size of the orifice hole will lower the performance of the gas refrigerator. This includes debris that may migrate into the orifice through the gas lines. This debris can be from a dirty tank, dirt or debris in the plumbing, or just left over material from construction or manufacturing. To ensure this does not cause the EZ Freeze gas refrigerators to loose their reliable performance, the orifice hole is protected by a micro fine filter screen just upstream from the ruby tip.

– Pressure Test Port –
This port allows diagnosis of the gas system using a manometer at the orifice while the gas refrigerator is in operation. This is the best way to detect a bad regulator or thermostat.

EZ Freeze fridge maintenance is cut down to a minimum due to the precision of this solid brass orifice.

Please also note that the orifice for the EZ Freeze Freezer and Blizzard Freezer is different from the refrigerator.  The Freezer orifice is a different size and shape which is vital for the freezer cooling unit functioning properly.

Adjusting the Temperature of Propane Gas Refrigerators

Posted on

How to adjust the temperature

Over the years we have sold thousands of Propane Gas Refrigerators and almost all of them have ended up in a remote location for use in a home or cabin that does not have electricity. Off-Grid owners seem to be more interested in adjusting their gas refrigerators to the proper temperatures than compared to owners of common electric refrigerators. The reasons for this can be;

Propane is usually trucked to the location or hand carried so it is safe to say that conserving of the gas usage is valued.

Most rural off grid homes, cabins, and cottages don’t have automatic climate control. This means the off grid refrigerator is subject to a wider range of ambient temperatures during the day as well as the seasonal changes.

Gas refrigerators are all manual temperature controlled. No digital thermostats or electronics whatsoever. This is what you would expect from a non-electric refrigerator.

For those seeking an education on setting the temperature, I’m going to split it up into two parts. Part Time Living and Full Time Living.

Part Time Living with a Propane Gas Refrigerator –
Since a fair number of our customers use the fridges at a weekend getaway or during a short vacation, they will typically turn the unit on upon arrival and shut it down when they leave. The largest propane refrigerator in the world made by EZ Freeze measures out to be 21 cubic feet. Chill down time for one of these units if it is empty will be 10 to 12 hours in 70 to 80 degree ambient air temperature. There are a few do’s and don’ts during this chill down time that is critical to operation during the next few days.

  • Do keep the door closed as much as possible.
  • Don’t load the fridge with any food or liquids that are not cold or frozen.
  • Do set the temperature setting to Maximum.

These are all common sense but you would be surprised at how many people overlook these rules. Especially rule #1. Guests and children that don’t understand absorption refrigeration will open the door to look inside by habit. It’s important to educate them.

After the chill down time is over, it is good practice to load the food goods in smaller amounts at timed intervals. Rule of thumb for ambient temperature food is 10 pounds every 2 hours. Loading frozen goods or cold foods will not have any adverse effects, so it’s OK to load your entire cache at this time. As for the ambient temp foods, if you load a high volume at one time, it is likely that the fridge will take 3 times longer to recover to safe food keeping temperatures than if you load only 10 pounds at a time over a longer period. Loading large amounts of ambient temperature liquids is also bad practice. Liquid is the most dense food and will take the most energy to cool. One way to cheat the process is to use smaller containers of liquids therefore increasing the air contact surface area. This helps greatly to get the drinks cold. 4 Quarts of water will chill or freeze faster than 1 gallon.

My advice to weekenders is to keep the thermostat set to maximum and replenish the ice trays or drinks at night right before bedtime. In some cases where a large party of guests are on hand, we suggest to not use the fridge for drinks. Using the fridge for drinks puts a huge strain on any type of fridge, gas (absorption) or electric (compressor). Using an ice chest for drinks keeps the fridge door closed more often and cuts down on the kitchen traffic too. Chefs love this idea.

Full Time Living with a Propane Gas Refrigerator –
For our “Full Timer” customers, your initial startup up rules are basically the same as the “Part Timer” rules. And you can also use these rules when you bring groceries home from the weekly shopping trip. 10 pounds every 2 hours still applies here. Beyond that, it is important to stabilize your temperature and thermostat setting. The most important area to monitor is the refrigerator interior temperatures. Due to the nature of how a gas refrigerator works, the thermostat setting will primarily affect the refrigerator compartment temperatures. There is no thermostat for the freezer. All the temperature setting is done by one thermostat located at the very bottom of the cabinet on the outside front near or behind the kick plate. This is true for all brands of gas powered home type refrigerators made by EZ Freeze, Diamond, Miller Refrigeration, Crystal Cold, Dometic, Sevel, Consul, Danby, and Unique. The control panel will be labeled with numbers that do not correspond with temperature. The numbers are simply a reference.

It is my belief that the best tool you can own when living full time with a gas fridge is a Remote Digital Thermometer. It allows the user to monitor the inside temperatures without opening the door. If an adjustment to the thermostat is needed, It will alert you either by the alarm or by what the display reads. In the case of the fridge stops working from a lack of gas supply, it may save you hundreds of dollars in groceries.

Stabilizing the temperature is fairly simple. It just takes a little time. Starting at the maximum setting as described in the initial startup, monitor the temperatures of the fridge compartment taking the “true” reading first thing in the morning before the door is opened. When this reading reaches freezing at 32 degrees, start to slightly move the dial toward the minimum setting by approximately 1/12 of a turn. Do this every morning until the temperature reaches your target. My target is usually 34 to 38 degrees.

Slight adjustments from this point can be made to compensate for seasonal changes and usage variations. We like to prejudge the high usage times and lower the temperatures in advance to get a head start on the recovery times. For instance, if you are planning a party or family get together, turn the thermostat toward maximum the night prior to the event.

Seasonal changes will usually demand an adjustment. Not only for temperature, but humidity levels will affect the settings more dramatically. High humidity will also produce more frost on the cooling fins and can reduce efficiency. Defrosting is another area of maintenance that can help with temperature stabilization.
One last note, a full refrigerator of cold food will be more temperature stable during the day than one with less food. It is due to the mass of food versus the mass of air. The food mass will retain the cold whereas the air mass will fall out when the door is opened.

 

About ammonia refrigerators and the absorption system

Posted on

What does the Ammonia do in the Absorption System?

Ammonia refrigerators, also known as gas refrigerators, operate from an absorption system that use ammonia as the active key ingredient are made specific as a non electric appliance. Typically you will see these units as propane gas refrigerators in recreational vehicles. Ammonia is the key ingredient among 4 total ingredients within the cooling unit also referred to as the absorption system. Water is the other liquid ingredient. Sodium Chromate is a powder substance that acts as an anti corrosive. This combats the highly corrosive ammonia. The fourth ingredient is Hydrogen gas which pressurizes the system to over 300 PSI. This is also true for ammonia freezers

Another common question is “Will freezing temperatures affect the cooling unit since it is filled with liquid?” The liquid is pressurized by the Hydrogen gas therefore it protects the liquid from freezing. The absorption system can be in use or just static in sub freezing temperatures without adverse affects.

With all 4 ingredients mixed together, the color is a bright yellow/green which is the original color of the Sodium Chromate. This color aids in leak detection. Either in wet form or dry state, the bright yellow/green color showing anywhere on the cooling unit coils will signal a leak. The other tell tale sign of a leak is the smell of ammonia. Ammonia has a very strong odor and is sometimes used in cleaning agents. it can literally take your breath away. In high doses it can be dangerous. For the most part, a propane powered refrigerator is considered safe and have been in continuous use in some cases for over 60 years. Read more about this…

About the Absorption Refrigerator

Posted on

What is an Absorption Refrigerator?

What is an Absorption Refrigerator? It is exactly what the name implies. The unit refrigerates by absorbing the warm air from the interior and expelling it to the exterior. Within the gas refrigeration industry, this process is accomplished by using a sealed absorption system containing a solution mixture of ammonia, water, sodium chromate, and hydrogen. The mixture is boiled by a flame usually fueled by either propane gas or natural gas.

The active ingredient is the ammonia which turns from liquid to vapor and back to a pure liquid again. This pure ammonia liquid absorbs the warm air through aluminum plates on the fridge back wall, freezer back wall, and freezer floor. This system uses no motors, compressors, or any moving parts. This is all accomplished by heat boiling the solution and it rising to the top of the sealed system where gravity takes over and allows the liquid to flow through the coil system at a rate determined by slight downward angles of the tubing.

The system is very simple in operation but very complicated in design. A very slight change in angle can alter performance and lower efficiency. A couple percentage difference in the solution ingredients will also change the gas refrigerator performance . Any weakness in a weld will shorten lifespan. All these factors must be correct in order to produce an efficient unit with top performance. Strict quality control is vital toward good production results.

At Warehouse Appliance, we rely on our many years of experience in using gas freezers and fridges, servicing gas refrigerators, and repairing gas fridges, and our warranty records to make the business decision of promoting the best brand. We choose the EZ Freeze brand.

We rate the EZ Freeze quality control as the best in the industry. EZ Freeze is the only company that produces the absorption system in house at the factory. No outside contracting is used in production. Over 50% of the production process is centered around quality checks within the production line of the product. A high pressure flushing occurs immediately after the welding process is complete to remove any weld slag or foreign objects that may be inside of the coils. The absorption system is then baked in an oven to relieve stresses and reduce the risk of stress cracks during its lifespan. The oven baking process also aids in sterilization of the internals of the absorption unit prior to filling. Baking off the oils and impurities. Each unit is then pressurized and leak tested before installation in the cabinet. The EZ Freeze absorption units are all made on a jig and foamed in a mold and are interchangeable at anytime in it’s life span with a new unit. This promotes consistency and reparability. It may seem excessive, but after all, this is the heart of the absorption refrigerator. It is also the most labor intensive part of production so it must be 100% before the unit ever gets to the consumer.

Further down the production line near completion, each unit is tested in the factory “Hot Room” which simulates a harsh operating environment with temperatures of 100 degrees Fahrenheit and high humidity levels. Each unit must pass well within the limits of good food keeping temperatures after this 16 hour torture test. The results are recorded on each refrigerator prior to packaging. No over company within this industry does this.

When asked about these strict quality control issues, EZ Freeze ownership replies “We realize that most of our fridges are used in remote areas. Hard to get to and from areas. It puts a great hardship on the consumer if there is a failure and we just don’t want to see that happen.” Click here to read about the history on propane refrigeration.
