Heat Pump

In the absence of chilling requirement, Thermax Heat Pump may be used for heating water.

Heat Pumps drive heat from a lower temperature to medium temperature, using high grade energy. Thermax Heat Pumps utilise steam, hot water, exhaust, fuel, geothermal energy or any combination of these heat sources, to pump heat. Heat pumps save approximately 35% of heat energy.

Thermax Heat Pumps offer highly efficient heating as well as cooling. Within industrial settings, heat pumps also deliver unparalleled process efficiency to meet the most exacting industrial heating and cooling requirements. Heat pumps can be used in any process where hot water up to 90 °C is needed, and a low temperature waste heat source, like cooling water, is available for heat recovery.
Thermax Heat Pumps are extensively used Scandinavian countries for heating applications. Heat pumps are also used in industries like: textile plants, edible oil, food, auto and white goods, etc. Heat pumps can also be used for feed water applications, for furnace oil fired boilers. Thermax has over 100 MW capacity of heat pump installations to its credit, installed across the globe.

Type-II heat pump also known as Heat transformer, in which medium grade heat is pumped to high grade heat. With a heat transformer, waste heat can be upgraded, virtually without the use of external driving energy. The input heat source i.e., Waste heat of a medium temperature is supplied to the evaporator and generator and useful heat of higher temperature is given off in the absorber. These heat transformers can achieve a delivery temperature up to 160 ºC, typically with a lift of 50 ºC.
