Product Description

Products Description

309 series thermostat is also called liquid expansion thermostat, pressure thermostat, which can replace the German E.G.O products.

 

Working Principle

Liquid expansion thermostat regulation of small tolerances, the thermostat by the capillary tube and temperature-sensitive temperature packet, temperature packet inside the liquid, when the temperature rises, the temperature packet inside the liquid expansion to promote the temperature control body of the mechanical structure to cut off the circuit. When the temperature drops, the liquid rest retracts. Turn on the circuit to continue to work. There is also a three-phase dual-control dual probe thermostat, with both temperature control and temperature-limiting dual function, when the temperature control part of the failure to a certain temperature can not cut off the circuit, the temperature continues to rise to another set of temperature-limiting temperature set temperature, the start of the secondary protection, cut off the circuit.

 

Application Areas

Electric water heaters, deep fryers, electric ovens, electric hobs, electric heaters, freezers, washing machines, central air-conditioning, two kitchen equipment, etc.

Services

•Sample test: Because of the specialness of bimetal thermostats, we need to conduct matching installation test before an order is placed. Through such test, we can also make sure that the performance of our products, temperature and other parameters are qualified in line with customers' requirements.

•Special requirements: We can design molds according to customers' drawings. If customers do not have drawings, but have samples, they need to send the samples to our engineers. We can measure the size and design the drawing, and then design the mold based on the drawing.

•After-sales service: If the temperature of the product needs to be changed, please feel free to contact us and we will always be patient in serving you. Instead of engaging in one-off business, we are seeking long-term cooperation, from which we can achieve a win-win situation.

•Payment: Currently we support T/T payment, and demand an advance deposit which is 30% to 50% of the total amount. The rest shall be paid off before delivery. As for other payment methods, it can be determined according to the sum of the order and the actual situation.
