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.

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.

Defrost Component Locations

On most frost free refrigerators, the evaporator (cooling) coil is inside the freezer compartment covered by a panel. The freezer fan motor is usually in the same general area.

The defrost heater is mounted onto or woven right into the evaporator coil in the freezer. The defrost termination limit switch is usually mounted on the side of the evaporator coil or on one of the connecting tubing.

The defrost timer can be in various places including behind the kickplate at the front of the cabinet, inside the fridge compartment possibly in a control panel along with the thermostat or on older models, at the back in the motor compartment by the compressor.
