LPG Gas Absorption
An absorption fridge uses heat to move the refrigerant through the cooling system. LPG gas is the most efficient way to run an absorption fridge, as the LPG gas can instantly produce a very hot flame.
240 V power will also cool an absorption fridge well, although the heating element needs to produce the same amount of heat as a gas flame, so it is not as efficient as on LPG gas.
12 V operation in an absorption fridge is often considered a holding mode only. The temperature of the fridge will remain steady, but the fridge will not have the power to cool down quickly. This occurs because the small 12 Volt heating element cannot produce the same amount of heat as a gas flame, so it uses a lot of electricity trying to keep up. The XD70 is the only 3-way chest fridge we sell. Most of our customers use it for long stints in the one place – like setting up camp for a couple of weeks at a time or for a more permanent off-grid situation.
A stable, level surface is required to operate an absorption fridge in the most effective way. So a moving car, caravan, motorhome or boat is not an ideal situation.
2-Way and 3-Way are terms referring to absorption fridges which can operate on 2 or 3 different power supplies. This is usually a combination of LPG gas and 240 volt (2-way) or LPG gas, 12 volt and 240 volt (3-way).
