Low Grade heat source is mainly from Boiler exhaust at 200°C as using Boilers for process or for Cogen for own power generation. Condensate recovery is also one more option to recover low grade heat source. Evaporator Condensate heat at 60-70°C is also available from chemical, distillation and refinery plants.

The Bry-Air Adsorption Chiller is based on an innovative green technology, and is the first of its kind in India, and is being manufactured in India.
