Description
The Heatcraft Refrigeration 4402S 70″ Heater 1200 Watts 230V is an electric heating element used to provide controlled heat for defrosting and temperature maintenance in refrigeration equipment. It operates by converting electrical energy into heat through a resistive element, warming coils or drain pans to prevent ice buildup and ensure proper system operation. It is mounted along evaporator coils or drain pans and connected to the power supply during servicing or replacement. Positioned within HVAC systems such as commercial refrigeration units, it supports efficient defrost cycles, maintains consistent performance, and assists to prevent operational disruptions.
