McQuay centrifugal compressor CE 087 Overhaul Parts

The McQuay CE087 refers to a centrifugal compressor size featuring an 8.7-inch impeller used in McQuay (now Daikin Applied) water-cooled centrifugal chillers, such as single-compressor (WSC) or dual-compressor (WDC, TDC, HDC) model lines.

Key Specifications & Details:

• Compressor Designation: CE087 (also variants like CE087L or CE087M with an 8.7-inch impeller diameter)
• Refrigerant: Typically engineered for positive-pressure HFC-134a (eliminating the need for a separate low-pressure purge system).
• Capacity Range: Size 087 chillers and assemblies typically span medium-to-large commercial cooling capacities (often paired across 30″, 36″, 42″, or 48″ vessel diameters depending on single or dual configuration).
• Capacity Control: Uses inlet guide vanes controlled via 4-way solenoid/needle valve assemblies or variable frequency drives (VFD) for modulation down to low part-load percentages.
• Support & Parts: Official service manuals, teardown guides, and specific component replacements (such as O-ring kits like 350306202K for CE087 front ends),plesae check below parts:
