Triveni Turbine Limited has launched a CO2-based high-temperature heat pump, developed in collaboration with the Indian Institute of Science, Bengaluru. The system can deliver heat up to 122°C and has achieved a coefficient of performance of 6. The heat pump uses CO2 (R-744), which has zero ozone depletion potential and a global warming potential of 1, as a refrigerant, replacing synthetic refrigerants with higher climate impact. It has been tested at Triveni Turbines’ Heat Pump Test Centre in Bengaluru. Designed for industrial applications, the product targets sectors such as pharmaceuticals, food and beverages, chemicals, textiles, distilleries, pulp and paper, and district heating and cooling. Applications include steam generation, pasteurisation, distillation, dehydration, dyeing, metal cleaning and drying.
