Process heat to 120 °C, without burning fuel
Most factory heat is needed well below 120 °C: washing, pasteurising, dyeing, plating, cleaning and drying. That heat usually comes from a diesel, gas, coal or briquette boiler. High-temperature heat pumps take it from ambient air or from your own waste heat instead, at three to four units of heat per unit of electricity at moderate lifts.
Process duties a heat pump can take over
The lower the temperature lift, the higher the efficiency. Duties up to about 90 °C are routine; 95–120 °C works best with a waste-heat source.
| Duty | Temperature | What a heat pump does |
|---|---|---|
| Washing, CIP and degreasing | 50–85 °C | Hot water for cleaning lines, tanks and parts, replacing boiler steam. |
| Pasteurising and food processing | 60–95 °C | Dairy, juice, beverage and ready-to-eat lines. |
| Dyeing and textile pre-treatment | 60–120 °C | Dye baths and scouring, often with heat recovered from effluent. |
| Electroplating and surface treatment | 40–95 °C | Plating baths, phosphating and anodising seal tanks. |
| Drying | 40–120 °C air | Closed-cycle heat pump dryers for food, spices, chemicals and timber. |
| Boiler feedwater preheating | 80–90 °C | Heat pump preheats; the boiler adds only the last step. |
| Waste heat recovery | 55–120 °C | Heat from compressors, chillers, cooling towers and effluent lifted to process temperatures. |

Engineering, not just equipment
Real industrial installations
Read how heat pumps were integrated at a multinational consumer-goods plant and a polymer plant.
MSME energy-efficiency support
We work with MSMEs on energy-efficiency programmes; see ADEETIE and Sunniva.
Process integration
We look at where the heat goes and where it is wasted, and often pair heating with cooling or heat recovery.
Made in our own factory
Designed and built in Asangaon, Maharashtra, so custom temperatures and configurations are possible.
Honest numbers
Capacity and COP come from our published datasheets; where a duty is outside them, we say so and estimate openly.
Service across India
A nationwide service network, spares from our own factory, and remote support by video call.
Before you decide
How hot can an industrial heat pump go?
Our high-temperature range delivers 80 °C from ambient air, the super-high-temperature range 95 °C, and the ultra-high-temperature range 120 °C using a waste-heat source plus ambient air. Steam above that is a specialist duty.
Is it worth it if we burn briquettes or coal?
On fuel cost alone, often not, because solid fuel is cheap. The case rests on removing fuel handling, ash, emissions and labour, or on heat recovery where the heat pump also provides cooling.
Can a heat pump work alongside our boiler?
Yes, and that is often the best first step. The heat pump preheats feedwater or process water, and the boiler tops up only when needed and stays as standby.
We have waste heat. Can a heat pump use it?
Yes. Warm water from chillers, cooling towers, compressors or effluent is an excellent source, and a water-source heat pump lifts it to process temperature at a higher efficiency than air-source.
What do you need for a proposal?
The process temperatures, flow or daily volume, running hours, current fuel and its cost, and any waste heat available. Photos of the plant room help.
