Packard CH2557 TUTCO 90W 460V Crankcase Heater

The Packard CH2557 is a 90-watt, 460-volt crankcase heater manufactured by TUTCO, designed to protect HVAC and refrigeration compressors from refrigerant migration and liquid slugging during off-cycles. This wrap-around band heater features stainless steel construction for durability and provides efficient heat transfer through full contact with the compressor housing.

Key Features:

• 90 watts of heating power at 460 volts for industrial and commercial applications
• Stainless steel construction operates reliably up to 300°F
• UL rated for safety and compliance
• Keeps crankcase oil up to 30°F warmer than system temperature
• Prevents refrigerant condensation in compressor oil during off-cycles
• Standard 30-inch lead length with stripped ends for easy installation
• Continuous sheath design ensures consistent heat distribution

Crankcase heaters are essential for preventing compressor damage caused by refrigerant migration into the oil during system shutdown. By maintaining optimal oil temperature, this heater protects against oil dilution, liquid slugging, and premature compressor failure, extending equipment life and reducing costly repairs.
