We translate your heating requirements into a reliable, tailor-made installation
From research question to industrial installation. We think along from the first idea.
The world faces the challenge of becoming less dependent on fossil fuels, without compromising reliability and availability.
With industrial heat pumps, Nijssen offers sustainable and reliable solutions for efficient heat generation for any process requirement. These systems can be easily integrated into existing processes. The use of residual heat sources and the delivery of temperatures above +100 °C are by no means exceptions. Thanks to intelligent control, heat is generated at the times when it is most efficient and cost-effective to do so.
Nijssen works with heat pumps based on natural refrigerants, including CO₂ (R744), ammonia (R717), isobutane (R600a) and propane (R290).
Fenagy specializes in large-scale CO₂ heat pumps for industrial and horticultural applications. Together, Fenagy and Nijssen bring technology and practice together: Fenagy supplies the heat pump technology, and Nijssen translates this into a complete, working solution for the greenhouse.
"Fenagy builds the heat pump. Nijssen executes the project."
