Single screw compressor

[Andy]

Having used both single and twin rotor machines, each has a place. In GENERAL, the single rotor machines do better on high evaporator temps or lower pressure ratio jobs and the power is better than a twin rotor.

A twin rotor machine will typically do better on a low temp evaporator of higher pressure ratios.

this would be the reason single screws are still applied.

I overhauled HS 34 and after some initial problems it is running very well. That is after 25 odd years of service.

Mono screws are long lasting in certain applications, but engineers have less experience working on them.

When you have worked on a few mono screws you will have better regard for them.
