Wax Elements

A wax element is a simple negative feedback controller. The wax element operates as a sensor, controller and actuator in a closed control loop.

Overview

FROM THERMAL ACTUATORS TO THERMOSTATIC ELEMENTS

Wax elements, also known as thermal actuators, thermal wax elements or thermostatic elements, are widely used technologies in automobiles. As well as for oil, fuel and even air flow control, they feature prominently in engine cooling systems – an essential component in a car.

Wax thermostats are well proven in the automotive sector. We can produce them in high volume which makes them a cost-efficient product.
