240V 230W LG Refrigerator Heating Element Tubular Refrigerator Defrost Heater 5300JB1091B

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

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.

Features

(1) Stainless steel cylinder, small volume, less occupation, easy to move, with strong corrosion resistance. (2) The high temperature resistance wire is placed in the stainless steel tube, and the crystalline magnesium oxide powder with good insulation and thermal conductivity is tightly filled in the void part. The heat is transmitted to the metal tube through the heating function of the electric heating wire,thereby heating up. Fast thermal response, high temperature control precision, high comprehensive thermal efficiency. (3) Thickened thermal insulation layer is used between the stainless steel liner and the stainless steel shell, which minimizes temperature loss, maintains temperature and saves electricity.

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.

Advantages and Disadvantages of Automatic Defrost Units:

Pros:

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 need to be cleaned out the unit once in a year. In addition to that, since there is no ice buildup in the fridge or freezer compartments, it will have more space for the food storage.

Cons:

However, Frost-free units cost more and use more electricity than manual defrost models. Because of the defrosting cycles, the temperature tends to fluctuate often, which means that they need more energy to restore the interior temperature. As a result, auto-defrost units consume more energy and make more noise during the operation.
