Carrier HT32CH216 Crankcase Heater
Protecting a compressor from liquid refrigerant migration during the off-cycle is a non-negotiable for system longevity, especially in 460V industrial applications. The Carrier HT32CH216 Crankcase Heater is a heavy-duty belt-type heater designed to maintain critical oil temperatures in compressors with a 6-7 inch diameter. Operating at 460V and 40W, this OEM replacement part (compatible with KAACH1901AAA) ensures that refrigerant stays out of the oil, preventing flooded starts and the catastrophic bearing washout often seen in poorly maintained split systems or rooftop units.
For veteran technicians, the HT32CH216 offers a straightforward field installation. This flexible band heater wraps securely around the lower compressor housing, providing even heat distribution at 50/60 Hz. It is commonly utilized in Carrier and Bryant models such as 24ABB3, 24ABC, and 25HCD series. By keeping the crankcase temperature above the refrigerant saturation point, this unit effectively eliminates liquid slugging at startup, maintaining compressor efficiency through the harshest winter cycles.
Key Benefits:- Ensures compressor reliability by preventing refrigerant migration into the oil reservoir.
- Vibration-resistant belt-style design fits 6" to 7" diameter scroll and reciprocating compressors.
- Optimized 40-watt power output at 460V for high-voltage commercial electrical systems.
- Direct OEM replacement for Carrier part number KAACH1901AAA, ensuring exact fitment.
- Durable technical construction withstands thermal expansion and contraction cycles.
What is the primary cause of crankcase heater failure in 460V systems?
Most failures in 460V units are caused by thermal fatigue or moisture ingress leading to short circuits. Regularly checking for a tripped breaker or blown fuse is the first step in troubleshooting a non-functional heater.
Can I install this heater if my compressor diameter is slightly larger than 7 inches?
No. The HT32CH216 is precision-engineered for 6-7 inch diameters. Forcing the belt can cause hot spots or lead to premature heater failure due to poor surface contact.
Should this heater run while the compressor is operating?
Typically, these are wired through auxiliary contacts to power on only during the compressor "off" cycle. Continuous operation during the "on" cycle is generally unnecessary and can lead to increased energy consumption.
Item is Non Cancelable / Non Returnable
