The BOHN 2470063 is a coil heater designed for commercial refrigeration applications. Coil heaters are electric resistance heating elements mounted on or within evaporator coil assemblies to perform defrost cycles, preventing frost and ice buildup that would otherwise restrict airflow and reduce system efficiency. This part is manufactured under the Heatcraft line of commercial refrigeration components and is installed by licensed refrigeration technicians and commercial HVAC-R service professionals.
Coil heaters of this type are typically found in commercial walk-in coolers, walk-in freezers, reach-in display cases, and other low-temperature refrigeration equipment where electric defrost systems are used. The 2470063 fits within Heatcraft and BOHN evaporator unit applications requiring a replacement defrost heater element to restore proper defrost cycle function.
Designed as an OEM-style replacement coil heater for Heatcraft and BOHN commercial refrigeration evaporator units requiring electric defrost heater service.
Coil heater replacement is performed by qualified refrigeration or HVAC-R technicians. Before servicing, disconnect all electrical power to the unit at the disconnect switch or circuit breaker and allow the coil to fully defrost and dry. Verify heater element resistance with a multimeter before installation to confirm the replacement is functioning correctly. Follow all applicable local electrical codes and the equipment manufacturer's wiring diagrams during reinstallation.
