Product Description
The KOLPAK 550000452 is a defrost heater designed for commercial refrigeration evaporator coil assemblies. This component generates the heat necessary to melt frost buildup from the evaporator coil during scheduled defrost cycles, maintaining proper airflow and system efficiency. The 550000452 is a three-fan-section unit, indicating it is sized for evaporator assemblies serving three fan zones. Installation and replacement are typically performed by commercial refrigeration technicians during planned maintenance or when defrost cycle performance degrades.
This defrost heater is suited for commercial walk-in cooler and walk-in freezer applications where Kolpak evaporator coil units are installed. The three-fan configuration indicates compatibility with larger evaporator coil assemblies commonly found in multi-fan commercial refrigeration units. It is a direct OEM-style replacement part sourced from the Kolpak parts and accessories line.
Key Features
- Three-fan evaporator section configuration for larger commercial coil assemblies

Installation Notes
Commercial refrigeration technicians should de-energize the refrigeration system and allow the evaporator coil to thaw completely before beginning heater replacement. Follow applicable local electrical codes and the unit manufacturer service documentation when disconnecting and reconnecting heater leads. Verify that the replacement heater is fully seated and all electrical connections are secure before restoring power and resuming defrost cycle operation.
