Calorstat / Thermocontactor
Here is our low temperature calorstat and thermocontactor section.
The thermal switch is a probe used to monitor the temperature of pressurized liquids.
They are used to make trigger the cooling circuit fan a little earlier to allow a lower operating range and therefore much faster cooling of the engine radiator.
The thermostat, also called calorstat, is an element of the cooling system which allows temperature regulation in the cooling circuit.
