Unlike piston compressors, in screw compressors there are no valves or other mechanical forces that can cause unbalance. This allows a screw compressor to operate at high speeds, while combining a large flow rate with small exterior dimensions. The ideal application of rotary screw compressors are continuous, workplace and industrial applications. There are two primary versions, oil-free and oil-injected, with options of fixed speed or variable speed drive operation.

The main benefit of rotary screw compressors is the energy efficiency. But this type of compressor has many other benefits. These include:

• low noise output
• small footprint for point-of-use installations
• no duty cycle
• continuous operation at temperatures of up to 46 degrees C
• low oil-carryover (as little as 3 ppm) in oil lubricated machines
• zero loss of capacity over time

The installation footprint can be further reduced with “full-feature” variants. Such machines have an integrated refrigerant dryer (dewpoint at compressor output of +4°C).
