A separate, motor-driven pre-lubrication pump is mandatory. It builds oil pressure before the main compressor start sequence begins and provides post-lubrication during coast-down. 5. Routine Maintenance and Inspection Intervals
Ensure the foundation can support the combined weight of the compressor, motor, and oil separator.
Each rotor is supported by two cylindrical roller bearings, allowing for oil-pump-free operation in over 90% of installations. Performance Data (Typical) howden xrv 127 manual
Oil System Setup: The XRV 127 relies on oil for cooling, sealing, and lubrication. Ensure the oil separator, cooler, and pump are correctly integrated according to the system piping and instrumentation diagram (P&ID). Operational Best Practices
