Triveni Launches India First CO2 Based Heat Pump

Triveni Turbines has introduced India's first CO₂-based high-temperature heat pump, marking a significant advancement in clean industrial energy. The pump, which was created in partnership with IISc Bengaluru, has a top-tier Coefficient of Performance (COP) of 6 and can provide heat up to 122°C. This makes it up to three times more efficient than conventional electric heating systems.

Triveni's innovative solution uses natural carbon dioxide (CO₂), a safe, non-toxic, and environmentally friendly refrigerant with zero ozone damage and limited global warming potential, in contrast to conventional heat pumps that use synthetic refrigerants with high global warming potential.

The product is supportive of India’s undertaking within the Kigali Amendment to cut hydrofluorocarbons (HFCs) as part of the country’s commitment to net-zero. Having been put through testing at Triveni’s Bengaluru test centre, the heat pump is most ideally suited to tropical climates and to industries needing high-temperature heating applications.

“It is a moment of pride for us as we unveil pathbreaking innovation that will lead the shift from fossil-fuel-based industrial heating and cooling solutions,” said Dhruv M. Sawhney, Chairman and Managing Director, Triveni Turbines. “Our new heat pump is 100 per cent engineered and made in India, and helps reduce energy consumption, operational costs and environmental impact.”

Developed collaboratively with IISc Bengaluru, the heat pump is one of the few in the world to reach 122°C using CO₂ in tropical conditions. "We think this is one of the first high-temperature heat pumps in the world," stated Dr Pramod Kumar of IISc. The heat pump has been developed to cater to industries such as pharmaceuticals, textiles, food, and chemicals with distillation, steam generation, and drying being typical uses for a cleaner alternative to fossil fuels.
