Howden: Xrv 127 Manual

An advanced feature of this compressor is the variable volume ratio (Vi), which can be easily adjusted by altering the position of the discharge port. The manual's capacity control section describes a slide valve mechanism. This hydraulic piston-driven valve changes the compression start point, recirculating gas back to the suction side and offering continuous, approximately proportional energy savings when reducing load.

Visit the official Howden Group website and navigate to the “Customer Support” or “Technical Library” section. You will need the unit’s serial number (located on the nameplate of the XRV 127 housing). After registration, you can download the exact manual tailored to your unit’s build configuration.

This section lists the approved lubricants for use with Howden screw compressors. Crucially, it highlights specific oils to be avoided due to potential damage to the shaft seal. For example, it warns against using certain mineral oils, such as BP Energol LPT-F (due to a low aniline point below 90°C) and Castrol Icematic 229, as these can be detrimental to the compressor's integrity. Always consult this section or your Howden representative to select the correct oil for your specific gas and application. howden xrv 127 manual
