VAM - Vapour Absorption Machines
Waste Heat Powered Cooling
System Overview
Vapour Absorption Machines (VAM) use heat energy instead of electricity to produce cooling. They operate on low-grade waste heat from industrial processes, solar energy, or steam, making them ideal for industries with waste heat availability. VAMs have very low electrical consumption and use environmentally friendly refrigerants.
