Capillary thermostats are intended to control temperature in most kinds of household appliances like: washing machines, ovens, freezers and heating technology – water heating, boiler for central heating etc. Operation is based on thermal expansion of liquid in closed system made of membranes, capillary and bulb. Length of capillary shape of the bulb and material (Cu or stainless steel) of capillary system are chosen in accordance with the application.

The basic family of capillary thermostat is KT 165.
