Temperature control units

HK 1502

Our temperature control units with oil as the heat transfer medium reach temperatures of up to 350 °C without pressure blanketing, while at the same time having a very compact and therefore space-saving design.

Our HK 1502 temperature control unit of dual-circuit design is especially suitable to regulate the temperature of consumers in the standard temperature range up to the high temperature range. Temperatures of up to 350 °C can be achieved without pressure blanketing. Featuring intelligent control and customised temperature control, our temperature control unit contributes to energy savings in the company. The CO2 footprint is kept low thanks to innovative production processes with a high in-house production quota and self-generated electricity. Last but not the least, the reusability of our assemblies also contributes to circular economy.
