Appliance

The electric damper is mainly used in air-cooled refrigerator controled by PCBA, the refrigerator manufacturers, according to the requirement of structure design, can use 1 single damper or 2 single dampers or double vents damper which respectively controlled two rooms.

  The damper is mainly mounted in the air vent of refrigerator, the setting temperature in fridge and variable temperature areas can be adjusted through opening or closing the damper controlled by PCBA, can be obtained in different temperature zones (such as soft frozen temperature -7℃ to -6℃; micro freezing -4℃ to -3℃, ice refrigerated temperature -2℃ to -1℃; low temperature -1℃ to 0℃; common cold storage 1℃ to 5℃), to meet the different requirements for food storage.

Damper Background

The damper is derived from the development needs of the market to fully research and enterprise restructuring, with the widespread use of PCBA in the refrigerator industry, some functional components have been widely used too, therefore, in 2014 Hengtong Co.,developed PCBA, ice maker, vacuum pump, electric damper, and have been gradually going into mass production. For electric damper, we based on absorbing products were improved and optimized for many times in the material selection, mold design and production process, so far, the technology, equipment and quality control ability of electric damper is the leading level in China.
