About Tetra Heat Pump, a product of Promethean Energy Private Limited
Tetra Heat Pump is the industrial heat pump brand of Promethean Energy Private Limited, based in Navi Mumbai.
What we build
An industrial heat pump picks up low-grade heat, from the air or from waste water, and raises it to process temperature. It runs on electricity, and every 1 kWh it uses delivers 2 to 5 kWh of heat, depending on the temperature you need. That's why the running cost comes in well below a boiler on diesel or gas.
Our units come in three configurations: air source, water source and cascade. They hold continuous output up to 120°C, with ±0.5°C control on the loop. Refrigerants include R1234ze and R245fa. The largest single machine is 1,450 kW. Our largest project is 5 MW, built from several machines.
We have more than 200 installations in service. Between them they have displaced over 500,000 tonnes of CO2.
The full specification is on the high temperature heat pump page. See how we compare with other Indian manufacturers.
Made in India
We design, build and service the equipment ourselves. In our experience of working with some of the biggest plants in India, this matters a lot. Every industrial heat pump is sized for your plant and wired into your controls. At some point it will need a compressor overhaul or a refrigerant charge. When that happens, you don't want the service engineer to sit at the far end of an import chain. With us, the people who built your machine also service it, and we respond within 24 to 48 hours.
Our heat pumps work with the control system you already have: BMS, SCADA or PLC, Siemens or Allen-Bradley, Modbus or BACnet. There is more on integration and on service and maintenance.

Our installations
Our case studies show how our heat pumps perform in real plants: a car paint shop, a dairy, paint booths that need tight humidity control, and a 200-room resort that cut its heating cost by 70%.
