From a thermodynamic viewpoint, thermal management is generally considered to mean the control of flows of energy (particularly heat flows).

From a vehicle engineering perspective, the term thermal management is understood to mean the energy-specific optimization of a vehicle's overall heat balance. The aim is to reduce both consumption and emissions, to guarantee engine cooling at every operating point and to optimize the level of comfort within the vehicle.

The aim is therefore to conduct the heat flows (heat supply and dissipation in the combustion engine, transmissions or passenger compartment) in the best possible manner, enabling fuel consumption to be reduced and, at the same time, helping to enhance the level of comfort in the passenger compartment.

Auxiliary heaters for low-energy-loss directly injected diesel engines and classic engine-independent heaters have the same aim: to deliver heat where it is needed in cold periods. In the passenger compartment, in the cooling water system and for defrosting. Our electromagnetic piston metering pumps are highly efficient and have a high metering accuracy. This is made possible by production tolerances of just a few micrometers.

Although air-conditioning systems have long been a series standard, they are still a cutting-edge  area of application. In just a few years time, new vehicle platforms will only be approved in many countries if their refrigerant does not exceed a GWP (Global Warming Potential) of 150. The inexpensive, non-toxic and readily available classic CO2 (R744) is the clear favorite here. Whilst possessing unrivaled economic and ecological advantages, its use also requires very sophisticated technologies.

Our electromagnetic proportional valves fulfill all required parameters – whether in compressor controls or in multiple evaporator circuits. They are sensitive and quiet-running – as a premium product should be.
