Oil-injected screw compressors VMY series

Screw compressors

Highest pressures. Full flexibility.

They supply the highest differential pressures or pressure ratios in the AERZEN product portfolio – the oil flooded compressor series VMY. The flow rate can be continuously controlled via the slide valve, which can also be used as a start unloading device. Rotor speed synchronization is not realized by timing gears (as in oil free compressors), but by direct power transmission of the driven rotor. The oil injection quantity regulates the outlet temperature. In case of wet gases, it is ensured that the oil is always compressed above the specific dew point temperatures. This reliably prevents water from escaping into the oil/gaseous mixture. Designed for years of uninterrupted operation, VMY compressors are the ideal solution for low molar weights, coolants, and generally for fluctuating operation conditions and gas compositions

Technical Data: Suction volume flow up to: 23000 m³/h, pressure range: -900 mbar to 25.0 bar g
