High temperature thermostats USH 400

The high temperature thermostats of the USH 400 line, with controlled cooling MVH (option), are specially designed for external systems at high temperatures up to 400 °C. The controlled cooling MVH enables controlled refrigeration at every temperature, for instance; when exothermal reactions occur. A further highlight is the efficient pump with a terrific 0.8 bar hood pressure.
