Refrigerator Defrosting Heater with Thermal Fuse Customized Home Appliance Parts Defrost Heater

Short Description:

Introduction：Refrigerator Defrost Heater

The defrost system activates a defrost heater in the evaporator section at the rear of the freezer. This heater melts frost off of the evaporator coils and then turns off. During defrost there will be no running sounds, no fan noise and no compressor noise.

Function: refrigerator defrost

Product Structure

Stainless Steel Tube heating element uses steel pipe as heat carrier. Put heater wire component in Stainless Steel Tube to form different shape components.

Applications

It is widely used to defrosting and heat preservation for refrigerator and freezer as well as other electrical equipment. It's with rapid speed on heat and with equality, security, through thermostat, power density, insulation material, temperature switch , heat scatter conditions can be required on temperature, mainly for frost elimination in refrigerator, frozen elimination and other power heat appliance.

How do the Auto Defrost units work?

Auto-defrost refrigeration units are designed with a fan on the compressor and an electric timer for an efficient operation. The timer controls the fan to blow the cold air in the unit, as well as the heating elements to melt any built up frost. During the defrosting process, heating elements behind the wall of the unit heat the cooling element (evaporator coil). As a result, any ice formed on the back wall melts and the water runs in the evaporator tray located on the top of the compressor. The heat of the compressor evaporates the water into the air.

Advantages of Automatic Defrost Units:

The primary advantage of automatic defrost units is the easy maintenance. It saves time and effort by eliminating the need for manually defrosting and cleaning the unit. It only needs to be cleaned out once a year. In addition to that, since there is no ice buildup in the fridge or freezer compartments, it will have more space for food storage.
