Victory VT50909601 Freezer Defrost Heater 525W 115V

The Victory VT50909601 Defrost Heater 525W 115V works by creating controlled electrical resistance heat to defrost the evaporator coils when the freezer is defrosting in commercial systems. It is activated by the refrigeration control system to heat the coil surface to melt the ice and drain it, keeping the air flowing in the freezer compartment, and is controlled by timed defrost cycles and thermostat feedback signals to the heater to control defrost cycle operation. It is placed inside the freezer unit housing in the evaporator coil assembly for even heating of the coil fins and defrost pathways during the automatic defrost operation cycles.
