Raypak CCH-1C Crankcase Heater 120 Volts

Product Description

The RAYPAK CCH-1C is a crankcase heater designed to protect compressor oil in refrigeration and HVAC equipment during off-cycle periods. Crankcase heaters prevent refrigerant migration into the compressor oil sump, which reduces the risk of compressor damage on startup caused by liquid slugging. This unit operates at 120 volts and is installed by licensed HVAC technicians as part of routine compressor maintenance or system commissioning. It is a direct-mount accessory that keeps the compressor crankcase at a stable temperature when the system is not running.

The CCH-1C is suited for residential and light commercial HVAC applications where compressor protection during idle periods is required. It is particularly relevant in climates with wide temperature swings or in systems that experience extended off-cycles. Technicians install crankcase heaters during new equipment commissioning or when replacing failed units as part of a compressor service call.

Key Features

• Operates at 120 volts for compatibility with standard low-voltage or line-voltage crankcase heater circuits
• Prevents refrigerant migration into compressor oil during off-cycles
• Reduces risk of liquid slugging and compressor damage on startup
• Direct-mount design for straightforward field installation
• Suitable for residential and light commercial HVAC systems

Compatibility

Designed as an OEM-style replacement crankcase heater for residential and light commercial HVAC compressor applications requiring a 120-volt crankcase heater.

Installation Notes

Crankcase heaters are installed by licensed HVAC technicians. De-energize the system and follow lockout/tagout procedures before servicing the compressor or installing the heater. The heater should be energized any time the compressor is not running to maintain proper oil temperature. Refer to the equipment manufacturer's wiring diagram and local code requirements when connecting to the control circuit.
