Industrial heat pumps

High-temperature heat pumps for industrial process heat systems

Industrial heat pumps are at the forefront of decarbonizing essential sectors like food and beverage, pulp and paper, chemicals, and textiles. These industries rely on high-temperature steam for critical processes such as drying, sterilization, and boiling. With a significant portion of industrial heat demand falling below 100°C, mature and reliable heat pump technology is already available to facilitate this transition.

Danfoss is your dedicated partner in navigating the shift to sustainable industrial heating systems. For processes requiring higher temperatures, we are pushing performance limits with technologies capable of delivering hot water up to 120°C now, with advancements towards 150°C on the horizon.

Spotlight: decarbonizing the food and beverage industry

A prime example of our technology in action is in the brewery sector. We have successfully partnered with breweries to refurbish older ammonia (NH₃) cooling systems and replace fossil-fuel-based boilers. By integrating hydrocarbon-based industrial heat pumps, these facilities can now generate high-temperature process heat and steam, dramatically reducing their carbon footprint and moving towards a fossil-free operation.

Decarbonizing with industrial heat pumps

Industrial heat pumps can replace fossil fuels by converting electrical energy input into thermal output.

The SuPrHeat Project: pushing temperatures above 100°C

The SuPrHeat Project: pushing temperatures above 100°C The SuPrHeat (Sustainable Process Heating) project is a cross-disciplinary research and development initiative with 16 partners across Europe. This project has been instrumental in advancing high-temperature heat pump technology.  

Key achievement: A 500 kW high-temperature heat pump is now operational at the Danish Technological Institute (DTI). Its key specifications include:

A pentane/butane cascade system capable of achieving a maximum condensing temperature of 150°C
Integration of Danfoss industrial refrigeration components and BOCK® compressors
A containerized design that eliminates the need for ATEX zone requirements

This project demonstrates the viability of high-temperature heat pumps using natural refrigerants for demanding industrial applications.

Case stories

97% Renewable Ringsted DHC’s heat recovery kickstarts a new era of greener district heating

Ringsted District Heating Company (DHC)—a large district heating utility in Denmark—has reduced its reliance on fossil fuels by 97% after Unicool installed an innovative heat recovery system using Geoclima heat pumps built with Danfoss Turbocor® oil-free compressor technology. With increasingly strict environmental regulations and growing costs, district heat plants are moving away from fossil fuels and turning to renewable energy—and innovative technology such as electric heat pumps and heat recovery—to reduce their environmental impact and maintain affordable heating.

Flue gas heat recovery to enhance sustainable heating for Frederikshavn residents

At Frederikshavn District Heating Utility (DHU), a 14 MW gas boiler is utilized during the cold months to ensure sufficient heat supply to the Frederikshavn community. A project was initiated by ME Production, involving Danfoss and heat pump OEM partner Energy Machines, to enhance energy utilization by recovering boiler flue gas heat. This was accomplished by modifying the existing economizer to increase the recovered capacity and boost boiler capacity with the resulting condensing function.

Revolutionizing chick hatcheries: Cutting natural gas with high-temperature heat pumps

For just over a year, the Van Hulst chick hatchery in Veldhoven (Netherlands) went completely without natural gas. Two-stage heat pumps now supply the heat and cooling needed to maintain the temperature of the chicken eggs. The new solution is climate-friendly, thanks to the use of natural refrigerants and operation with solar electricity – and lowers energy costs by approx. 30,000 euros per year.
