MTW1 Wax motor actuator

Characteristics and usage

• Simple and reliable structure，easy to install. High thrust, no noise, energy-saving
• Widely used in liquid and detergent distributors, washing machines， dishwashers，refrigerators，electric ovens，embedded steam stoves，
• ventilation fans, air flow controllers，air dampers, water flow reversing valves, thermal delay devices, safety buckles，sound insulation devices and air door
• controllers of air-cooled refrigerators, etc.
• Working principle of wax motor actuator
• The wax motor actuator is a driving device. The device consists of a thermistor with positive temperature coefficient, which is installed in a sealed container filled with solid wax. When the thermistor is energized and generates heat,
• causing the solid wax in the container to reach a certain temperature, the wax begins to melt and expand, pushing the piston pressed by the spring to move outward. By relying on the guidance of the inner cavity of the shell and the
• structure of the spring, the piston can pull in or push out a load. When the power of the thermistor is cut off, the liquid wax cools and contracts, while the spring resetting force causes the piston to return to its original position.
