The XRV 127 utilizes a male rotor with four lobes and a female rotor with six flutes. Oil-injected rotary twin-screw. Volume Ratio (Vi): Manually adjustable from 2.6:1 to 5.0:1.
Replace the main oil filter element to catch assembly debris. Clean the suction strainer mesh. 4,000-Hour / Annual Service
Refrigerant dilution. If liquid refrigerant enters the oil separator, it dilutes the oil, dropping its viscosity and lowering apparent pressure. Turn on oil heaters. Symptom 3: Excessive Vibration or Noise
The XRV 127 belongs to Howden’s range of oil-injected screw compressors. It features a variable volume ratio ( Vicap V sub i
If you have specific issues,I can provide more details based on your needs. XRV 127 Service Manual - Sept - 2013 | PDF | Valve - Scribd
While specific limits vary based on the refrigerant or gas composition (e.g., Ammonia/R717, CO2, Hydrocarbons), standard baseline parameters include:
is optimized for horizontal oil separator packages. It features a male driving rotor with four helical lobes that intermesh smoothly into a six-flute female driven rotor. Specification Value Displacement (Cubic Volume) 207 CFM (352 m³/hr) at 3,600 RPM Hydraulic Test Pressure 37.00 Bar G (approx. 536 PSIG) Max Working Pressure (High Side) 21.00 Bar G Max Working Pressure (Low Side) 5.00 Bar G Bare Shaft Dry Weight Suction / Discharge Ports 4-inch / 2-inch Volume Ratio ( Vicap V sub i ) Range Variable from 2.6:1 to 5.0:1 Volume Ratio ( Vicap V sub i ) and Capacity Control
The manual is organized into several logical sections, each covering a specific aspect of the compressor's lifecycle.
The compressor is designed to handle liquid refrigeration injection (superfeed) for increased efficiency. 5. Maintenance Procedures and Schedules
Take an oil sample for laboratory analysis (check for acid, moisture, and metal PPM). Replace the oil filter cartridge.
