HVAC / Indoor Climate Control

Meeting the increasing NVH Requirements

Whether alternative refrigerants, the latest battery technologies or optimised air conditioning units - for the areas of HVAC and passenger compartment air conditioning, we implement the constantly growing requirements in the automotive sector quickly and efficiently. We support refrigerant development, develop new systems and optimise vehicle air conditioning. Energy consumption, environmental protection and comfort play an essential role. With our NVH measurements, we ensure both optimal air-conditioning comfort and low interior noise.

Thermal Management Redefined

In the context of new drive technologies, we are continuously working on further developments with our system partners in the field of vehicle air conditioning and aggregate cooling. We design test benches and system components that enable efficient development of the heart of every cooling system - the compressor. The latest generation of electrically driven compressors (eKMV), which find their use in electric and hybrid vehicles, was accompanied by IPETRONIK's engineering expertise - from development to series production.
