Copeland 918-0019-08 Crankcase Heater

The Copeland 918-0019-08 Crankcase Heater is a critical HVACR service part designed to prevent refrigerant migration and maintain oil temperature during compressor off-cycles. This belt-type crankcase heater is engineered for a 480V electrical configuration, delivering a steady 70W output to ensure optimal viscosity of the compressor lubricant. Proper heat distribution prevents liquid slugging at startup, extending the service life of high-capacity refrigeration systems. Utilizing a flexible wrap-around design, this 70 watt heater ensures a secure fit on compatible compressor housings, providing uniform thermal transfer. For technicians managing industrial cooling systems, integrating this Copeland compressor heater is a standard preventative measure against mechanical failure caused by cold oil. Ensure proper electrical clearance and contact pressure during installation to maximize heat efficiency. This industrial HVAC heating element is built to withstand rigorous high-voltage environments, providing consistent thermal management for commercial compressor oil heating applications.

• Optimized Oil Path: Maintains lubrication at the correct temperature to prevent premature bearing wear.
• Direct Heat Transfer: Belt-style design provides superior surface contact compared to immersion styles.
• High-Voltage Compatibility: Specifically rated for 480V 3-phase systems common in industrial HVACR setups.
• Startup Protection: Minimizes the risk of liquid refrigerant dilution in the oil sump.
• Durable Construction: Engineered to withstand thermal cycling and high ambient temperatures.

What is the primary function of this 70W crankcase heater?
It prevents the migration of liquid refrigerant into the compressor oil during idle periods, ensuring that the lubricant remains at the proper viscosity for a safe startup.

Can this heater be used on 208/230V systems?
No, this unit is specifically rated for 480 volts. Installing it on a lower voltage will result in insufficient wattage, potentially leading to compressor damage due to cold oil.

How tight should the belt be during installation?
The heater must have firm, continuous contact with the compressor shell to ensure efficient heat transfer and prevent the element from burning out due to air gaps.
