Wax elements are at the heart of all our thermostats and thermostat inserts. These maintenance-free, durable elements have proved their worth in millions of applications, and can be tailor-made to your individual specifications. We manufacture a wide range of variants with actuating forces.

Warming the wax element increases the volume of the wax, thereby moving the piston. If the temperature drops, the volume is reduced, and a spring forces the piston back to the starting position.
