How does a Servel refrigerator work?
The hydrogen passes across the surface of the ammonia and lowers the ammonia vapor pressure sufficiently to allow the liquid ammonia to evaporate. The evaporation of the ammonia extracts heat from the food storage space, as described above, thereby lowering the temperature inside the refrigerator.
When did they stop making gas refrigerators?
1920s-1950s: Gas-Fueled Refrigerators Yet, gas refrigerators were not purchased by as many households as electric refrigerators, and Servel was essentially the only major manufacturer of gas-absorption refrigerators in the U.S. between 1927 to 1956, when it stopped producing refrigerators.
Was there ever a gas refrigerator?
Gas refrigerators have been in production since the early 1900’s and used in households as a standard common everyday appliance until the late 1950’s when electricity and electric refrigerators became the normal. Although they were not as common as an electric refrigerator after that , they did not go extinct.

How much propane does a Servel refrigerator use?
The serval (Leptailurus serval) is a wild cat native to Africa. It is rare in North Africa and the Sahel, but widespread in sub-Saharan countries, except rainforest regions. Across its range, it occurs in protected areas, and hunting it is either prohibited or regulated in range countries.
Are there still gas refrigerators?
The gas consumption on a modern day gas refrigerator is less than half the amount than an older SERVEL is due to the designing of this cooling system. An average amount of propane used in the older SERVELS was 3-4 lbs.a day
How does a liquid propane refrigerator work?
A propane fridge has a sealed network of tubes and chambers holding water, ammonia and hydrogen gas. A propane flame heats a chamber holding a solution of water and ammonia until the liquid boils. The ammonia gas rises to another chamber, the condenser, where it cools back into a liquid.
How does kerosene fridge work?
No longer in business, Servel manufactured gas refrigerators between 1933 and 1957. The Servel refrigerators in question are no longer being produced and are in no way associated with the Dometic Corp., the current manufacturer of Servel brand name products.
How does a natural gas refrigerator work?
Heat is applied to the ammonia and water solution in the generator. (The heat comes from burning gas, propane or kerosene.) As the mixture reaches the boiling point of ammonia, it flows into the separator. Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid.
When did they stop using Freon in refrigerators?

How long does gas refrigerator last?
In 1994, governments banned the use of R-12 in new refrigerators and air-conditioning systems due to its damage to the ozone layer. Since 1990, the less harmful replacement for R-12, R-134a, has been used in many old systems.
When did refrigerators become electric?
If you’re using a standard 20-lb propane tank, you can expect it to last around 11 days (non-stop) before needing to replace or refill it.
Are there any gas refrigerators?

When were gas refrigerators invented?
1876. German engineering professor Carl von Linde patented the process of liquefying gas that has become part of basic refrigeration technology. His findings led to his invention of the first reliable and efficient compressed-ammonia refrigerator.
