Our thermal actuators are powered by regulating the temperature in air, water and oil. They have been developed for the use in thermostatic radiator valves, secondary coolant valves and transmission oil valves. Here, wax elements in the actuators work with the thermostatic radiator valves on each radiator, enabling the opening and closing of the valve according to the room’s temperature. The wax elements are integrated into an anti-freeze module screwed onto an external tap. This allows the opening of the valve when the outside temperature is decreasing.
