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.

– 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.

To purchase a replacement EZ Freeze gas orifice see our EZ Freeze parts category.

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.

Danby Propane Refrigerator – vs – the EZ Freeze EZ-10

Imported and private labeled by the Danby Corporation, this gas refrigerator is identical to the Consul Fridge. Both made by Whirlpool of Brazil, these units only differed by the name plate on the front door. Production of these units ended in 2012 and are not available anymore. No plans to bring the brand back are on the horizon. Some parts are available and service is still available as well. Our service department continues to repair them for our local customers or those who don’t mind trucking or shipping them to our facility. Others may choose to get outside help by purchasing the Danby Repair DVD. On today’s market a well kept unit is resalable from anywhere between $600.00 and $1000.00. A comparable new model made by EZ Freeze (EZ-10) will sell for $1399.00 on today’s sale marketplace. Both are considered a small propane refrigerator.

With the proper care and maintenance the Danby refrigerators were a great asset to any off-grid vacation home, hunting camp, or full time off-grid home. One of the major draw backs to the Danby Consul fridge was the small freezer size. The 1.1 cubic foot capacity is only large enough for 2 frozen chickens and a couple of ice trays. The newer EZ Freeze EZ-10 freezer compartment measures out at 2.2 cubic feet which is moderate for a cabin size fridge. The Danby Consul fridge has been the industry leading cabin size fridge for many years, but with them being discontinued the choices have narrowed to the 10 cubic foot size. Cost is slightly higher but the gain in capacity and much less maintenance and headache is well worth the price. The EZ Freeze propane refrigerator for sale on our site here

Consul Propane Refrigerator – Service Notifications

Consul Refrigerator – Service Issues

In the Mid 1980’s, there were very few gas refrigerators in production on the retail market. In fact there were only 2 brands that were considered reliable. One brand name was the Consul. Made in Brazil and imported into North America. Based on an average electric fridge, the Consul was small. It was common place for a home owner to purchase 2 and use them side by side to accommodate the entire family. Although the 1940 model Servel propane gas refrigerators looked much larger, the capacities of both brands were very similar at about 8 cubic feet.

Compared to the 1940 Servel units, the Consul gas fridge freezer was much more efficient and reliable. Compared to a 2014 model EZ Freeze, the Consul is slightly less efficient and much less reliable. Considering the age of design of the three mentioned fridges, the reliability is par for the course based on age of design.

What design issues does the Consul propane refrigerator have? Most of the design flaws center around the burner area. The most common issue that we see is the burner burning foul due to ingested debris. This can not only cause the LP refrigerator to not cool properly but also be dangerous to the homeowner if left unattended. Very high levels of carbon monoxide can result in health issues. The old 1940 Servel units showed these same traits but on a much worse scale.

When the burner gets fouled by debris the flame puts off soot through the exhaust. This soot will coat the boiler and lower the boiler temperature and as a result the refrigerator interior temperature will rise above safe food keeping temperatures.

Pictures on this page show a severely neglected Consul burner and the resulting soot ball the was cleaned out by our service technician. This is one of the worst cases we have seen. This Consul unit required a full burner rebuild. When it left the shop, it was in good working order with interior temperatures at 29 degrees Fahrenheit in the refrigerator compartment.

We used the same step by step procedure for this rebuild as we show in the Danby / Consul Repair DVD.
