High Temperature Heat Pump Manufacturer in India

A high temperature heat pump (HTHP) is an industrial heat pump that delivers heat above 100°C by upgrading waste heat or ambient heat. Rockshell Corp is a high temperature heat pump manufacturer in India, building industrial systems for hot water up to 130°C and steam up to 200°C for process heating, drying and evaporation.

Why High Temperature Heat Pumps Matter for Indian Industry?

Many plants still make process heat from diesel, furnace oil orcoal-fired boilers. Because a heat pump moves heat rather than burningfuel, its coefficient of performance (COP) is greater than 1, and awell-matched system can deliver several units of heat per unit ofelectricity. The temperature lift between your heat source and yourprocess temperature is the main factor in COP, which is why propersizing matters.

Industrial High Temperature Heat Pump FAQs

What is a high temperature heat pump?

A high temperature heat pump is an industrial heat pump that delivers useful heat above about 100°C. It captures waste or ambient heat and upgrades it with a compressor, providing hot water, steam or hot air for process use.

How efficient are high temperature heat pumps compared with boilers?

A fossil boiler converts fuel directly to heat at an efficiency below 100%. A high temperature heat pump typically delivers a COP of about 2 to 4, and much higher in steam applications with a small temperature lift, meaning several units of heat per unit of electricity.

Can a high temperature heat pump replace my boiler?

In many cases it can replace or reduce boiler load for hot water, low-pressure steam and drying. We assess your load pattern, peak demand and heat sources first, and can add a buffer tank to handle peak demand.

Which refrigerants do your high temperature heat pumps use?

We use low GWP HFO refrigerants such as R1233zd(E) and R1234ze(E), selected for the required temperature.

What is the typical lifespan of an industrial high temperature heat pump?

With proper operation and maintenance, industrial HTHPs typically last 15–20 years, offering long-term energy savings and carbon reduction benefits.

Can high temperature heat pumps recover waste heat?

Yes. Industrial heat pumps can capture low-grade waste heat from industrial processes and upgrade it to usable high-temperature heat, improving overall energy efficiency.
