CONICAL ROTARY COMPRESSOR is a new type of screw compressor. Screw compressors are known to produce high pressure without vibration, and at very high efficiency. However, before only large screw compressors were available (2kW and bigger). Vert’s new conical technology has changed that and opened a new market of small – even miniature – screw compressors that produce high pressure without vibration.
In the Vert’s conical compressor, the Inner conical screw revolves inside the Outer conical screw. This compact and efficient configuration is an innovation that was demonstrated by Vert Rotors in 2013. It defines a fundamental difference from traditional screw compressors, which include two screws sitting side-by-side in a housing. In the traditional twin-screw system (developed 80 years ago) the clearance between the two screws and the housing allows the high-pressure gas to leak back, and efficiency is reduced. In the Conical Rotary Compressor there is no housing, which makes it very difficult for high-pressure gas to escape. This gives a great advantage in efficiency.
This in-built advantage in efficiency of the Conical Rotary Compressor allows Vert to make 100-1,000 W screw compressors, which has not been possible before.
