Liebert 172147P2S Crankcase Heater
The Liebert 172147P2S Crankcase Heater is a critical OEM replacement part engineered for high-performance precision cooling systems. Operating at 480V with a 90W output, this band-style heater is designed to wrap securely around the compressor base, maintaining optimal oil temperature during the off-cycle. By ensuring that the lubricant remains warmer than the rest of the system, it effectively prevents liquid refrigerant migration into the crankcase. This eliminates the risk of oil dilution and destructive foaming upon startup, which are leading causes of bearing washout and premature compressor failure in mission-critical Vertiv Liebert units.
Designed for the rigorous demands of thermal management in data center environments, the 172147P2S features a robust heating element with flexible arms for easy compressor installation in tight spaces. For veteran technicians, this part is essential for maintaining system reliability in cold-start conditions and extending the operational lifespan of scroll compressors. The 480V configuration ensures direct compatibility with industrial-grade power supplies, providing the thermal inertia required to keep your HVACR systems running without interruption.
Key Benefits:- Prevents Refrigerant Migration: Keeps lubricant temperatures above the refrigerant boiling point to avoid oil-refrigerant mixing.
- Optimized 480V 90W Performance: Specifically calibrated for high-voltage industrial applications to provide consistent heat transfer.
- Ensures Proper Lubrication: Protects critical internal components from "dry starts" caused by refrigerant-diluted oil.
- OEM Precision Fit: Authentic Vertiv Liebert part ensures exact crankcase heater compatibility for DS, DSE, and Challenger models.
- Easy Installation: Flexible band design with a secure fastening clip allows for rapid field replacement without opening the refrigeration circuit.
Why is my compressor making a loud noise on startup in cold weather?
This is often a sign of liquid slugging or oil foaming because the oil is too cold. A functioning 480V 90W crankcase heater like the 172147P2S is necessary to preheat the oil for at least 8-12 hours before startup to ensure a smooth, quiet transition.
How do I test if my Liebert 172147P2S is working?
With power disconnected, check the electrical resistance at the leads. A failed heater will often show an "open" circuit (infinite resistance). You should also verify that the heater is receiving the correct 480V supply when the compressor contactor is de-energized.
Can I use a higher wattage heater as a substitute?
It is critical to match the OEM specifications. Using a higher wattage than the 90W rating can cause localized overheating, potentially damaging the compressor shell or the heater element itself.
