Refrigerant

Fully exploiting Development potential for E-Mobility

The range of electric vehicles depends on various factors, such as battery capacity or air conditioning. But the right refrigerant can also increase efficiency. Together with our partners, we are developing new refrigerants for thermal management in all-electric vehicles. Our customised component and system test benches meet every requirement. Whether developing new cooling systems for hybrid drives, battery and engine cooling - we develop, test and validate with all types of refrigerants, including R744 (CO2) and R290 (propane).

Developing and Safeguarding Circuits with alternative Refrigerants

For years, the automotive industry has been faced with the task of finding a replacement for the refrigerant R134a, which is no longer permitted in the EU. For this purpose, refrigerant circuits with alternative refrigerants must be developed and secured. In order to master these challenges, we accompany and support our customers at all times in a committed and professional manner. With our expertise in measuring, analysing and evaluating the latest HVAC technologies, we contribute to the development process and ensure that our climate will soon be even more protected with the next generation refrigerant.
