Screw Compressor Spare Parts Two Stage Ghh RAND Air End CDA80

The CDA80 is a double stage, gear driven and oil-free screw compressor block, which can be used for general industrial applications.

Ultracoat

Using Ultracoat in our oil free compressors is the key to their reliability, long life, and excellent efficiency. The outstanding efficiency of our dry-running screw compressors is down to our coating (Ultracoat) which we use for coating our rotor profiles, sealing journals, housing bores, and end covers.

This coating fulfills two essential requirements:

• One is for improving the efficiency which also reduces discharge temperature of the air end, increases volume flow, and decreases power consumption.

• In addition, this coating offers highly efficient corrosion protection even under extreme conditions at 270°C.

In order to achieve high efficiency, the Ultracoat sacrificially wears during the first test run. This is like lapping in components that ensure that the clearances are as small as possible and this, among other things, is what makes our oil free machines so efficient.
