The production of this product has been discontinued.

Thermostats combined with stainless steel tank and compressor cooling system. At temperatures above the boiling point or below the freezing point of water, a special liquid must be used as a heat transfer fluid.

The devices are suitable for both internal and external circulation, so external devices can also be thermostated. The controllers marked T100 and TC150 (the marking is included in the second part of the model number) have an LED display, while the thermostat heads marked T200 and TC250 have a touch screen.

A more detailed description of the thermostat heads and their technical data (accuracy, heating power) can be found on a separate page.
