Wanson Israel is the exclusive corporate representative of Thermax, a global leader in Absorption cooling systems (www.thermaxindia.com). Wanson Israel was the first to introduce the new generation of reliable efficient Absorption Chillers in Israel.
A vapor absorption chiller machine (VAM) is a machine that produces chilled water using a heat source rather than electrical input as in the more familiar vapor compression cycle. It seems unreasonable that cooling can be achieved with heat, but that is what occurs within an absorption chiller.
Thermax's chillers are considered the most reliable machines available. They can supply cold water for industrial process as well as comfort air-conditioning. Thermax's absorption chillers are installed in numerous prestigious locations around the world such as the BBC studio in the UK, IBM Data room in Syracuse University NY, the Berlin Airport, the Rome airport, Daimler Chrysler, Germany and many more.
Both vapor compression and absorption refrigeration cycles accomplish the removal of heat through the evaporation of a refrigerant at a low pressure and the rejection of heat through the condensation of the refrigerant at a higher pressure. The basic difference is that an electric chiller employs a mechanical compressor to create the pressure differences necessary to circulate the refrigerant whereas the absorption chillers use heat source and do not use a mechanical compressor. The differences cause an absorption system to use little to no work input, but energy must be supplied in the form of heat. This makes the system very attractive when there is a cheap source of heat, such as solar heat or waste heat from electricity or heat generation.
