The genuine OEM Lennox 11B95 is a Copeland ZR94KCE-TFE-950 scroll compressor rated at 94,000 BTUH, running on 575 volts, 3-phase power with R-407C refrigerant. As the core of your Lennox commercial cooling system, it compresses refrigerant vapor to drive the entire refrigeration cycle. Its scroll design offers smoother, quieter, and more efficient operation than older reciprocating compressors, and it is matched to Lennox factory specifications for an exact fit.
Common signs of compressor failure include insufficient or no cooling, the unit tripping its breaker on startup, loud mechanical noises, excessive vibration, overheating, or repeated short-cycling. A grounded or open winding on a three-phase compressor will typically prevent the unit from starting at all.
Because this is a 575V R-407C application, using the exact OEM 11B95 is critical — voltage, refrigerant compatibility, and displacement must match precisely to protect the sealed system and maintain warranty coverage. Aftermarket substitutes risk mismatched oil charge and electrical specs. Order today with same-day shipping to get your system back online fast.
