Their ingenious technology is one of their outstanding features: Rotary compressors compress gas by using two meshing helical screws, which are also known as rotors. Timing gears ensure that the male and female rotors maintain a precise alignment in the case of a dry-running rotary screw compressor. In the case of an oil-lubricated rotary screw compressor, lubricating oil bridges the space between the driving and the driven rotors. This provides a hydraulic seal and also transfers mechanical energy between the two rotors.
A rotary screw compressor is a great alternative to a piston compressor, and they are built specifically for long lifetimes of reliable use and for operations that require up to a 100% continuous duty cycle.
You can choose from a basic design, which is usually available in the lower kW/HP ranges, all the way to a variable speed drive (VSD) compressor, which has a higher investment cost but typically makes up for it with double digit energy savings.
Because a VSD compressor adjust its speed to the compressed air flow, they don’t waste electricity. That means that VSD technology is particularly useful if your operation has a fluctuating demand for compressed air, resulting a large energy savings.
