Norlake 146398 Defrost Heater Commercial Refrigeration

Product Description

The NORLAKE 146398 is a low-temperature defrost heater designed for commercial refrigeration equipment. Defrost heaters generate controlled heat to clear frost and ice buildup from evaporator coils, allowing the refrigeration system to maintain efficient heat transfer and consistent temperature performance. This component is a direct OEM-style replacement part intended for service and maintenance work on NORLAKE commercial refrigeration units. Installation is typically performed by a qualified refrigeration technician as part of a scheduled defrost system service or component failure repair.

This defrost heater is suited for low-temperature commercial refrigeration applications, including walk-in coolers, walk-in freezers, and reach-in refrigeration cases where evaporator coil icing is managed through timed or demand defrost cycles. It is intended for commercial foodservice and food retail environments where reliable defrost performance is critical to maintaining safe product temperatures.
