InvenSor GmbH has released a line of adsorption chillers, which produce cold water using heat instead of electricity to drive the system. Typical heat sources include combined heat and power units, solar thermal systems (solar cooling), and industrial waste heat.
The chillers are available in two versions. The HTC 18 plus (high-temperature chiller) is suitable for use in warm regions, where it can operate even at high recooling temperatures of 40°C and above. It has a nominal cooling capacity of 18 kW (5.1 RT or 61,400 Btuh).
