Merits of open-type single-stage inverter screw compressor unit
● SRM high- efficiency screw compressor: higher COPthan the same type of compressor units.
Open  asynchronous motor with high efficiency and lownoise; the permanent  magnet synchronous variablefrequency motor is also available for  selection.
Differential- pressure oil supply system with a small oilpump as pre- lubrication: energy- saving and reliable.
Economizer installed: make the high pressure liquidfrom the condenser subcooled, thus improve COP ofthe system.
Fully  automatic one- key start- up; real- time analysisand monitoring of the  operation status; saving andkeeping of the historical data, remotely  control.
Automatic capacity control make the unit run with highefficiency under various working conditions.
The preventive safety and protection system:unmanned but safe and reliable.
All the components are from well-know nmanufacturers: high reliability and guaranteed quality.
