Membrane Chiller

A chemical-free, thermally activated air-conditioning system.


Technology Overview: This refrigerant-free air conditioning system uses specialized water permeable membranes and system architecture instead of a heating coil to cool and dehumidify air. The membrane chiller is driven by low temperature heat, including available low-temperature waste heat from CHP, solar, and other processes, and consumes 70% less electricity than conventional air conditioners. Unlike other evaporative systems, the membrane chiller will operate in any climate.
