Wax Thermostat

Wax thermostat is the most widely used in combustion engines, and SDZ possesses and masters matured skills of its development and production. Wax pellet in the copper expands when it heats up and contracts when it cools.

Technical Information of Wax Thermostat

Characteristics of Wax Thermostat

The wax is enclosed in a metal capsule in touched with water. The valve close when the wax is cooled. It blocks the passage of water into the radiator. When the wax is heated and expands, and the rod is expelled. The valve opens and wax is cooled, and closed by spring.

Structure of Wax Thermostat

Wax thermostat is mainly composed of

1. main valve

2. bypass valve

3. inductive element (wax pellet)

Inductive element is the core part of thermostat work

Wax Thermostat has simple structure and low cost, thus has a wide application in conventional vehicle.

Application Of Dual Thermostat

Only one thermostat on the engine cannot meet the optimal operating temperature requests of different parts of the engine. To solve this situation, SDZ technology support the application of a dual thermostat. It includes two thermostats with different opening temperatures.
