Re: McQuay Screw Compressor
Did'nt think McQuay responds very well, full stop! I thought they had loads of problems with Frame 2 and 3's?
Re: McQuay Screw Compressor
Hi Steve,
True enough. I've heard plenty of stories about shredded star gate wheels and stuff stripping off components, but never seen it myself. ( I hope I never see it - for that matter) I heard that they fixed the issue with breaking wheels about 5 years ago. This compressor is only about 3 years old so we might have half a chance.
I suppose the easiest way is to just buy a variable speed chiller - but it's impossible to justify to the bean counters when it is so new - especially if it is possible to retrofit it for a lot less cost.
Re: McQuay Screw Compressor
I gather that McQuay fixed a load of issues with the Frame 4, but then I thought they have been around for longer than 3 years? Unless your machine is second hand or sat around someplace for a while?
I gather from my boss that when he attended the IKK in Germany this year, he saw a few manufacturers had begun producing compressors specifically to be used for variable drives. Hanbell are one, not sure who else. I guess there must be longevity issues with a standard slider load screw, perhaps with lubrication at lower speeds?

I'm thinking a good first port of call would be Mr Tony Pitt at the factory in Rome.
Call Marco at the factory on +39 0693731311 and ask him to put you through to Tony up in the compressor R&D section.
I have attached a picture of Tony's office :)
Re: McQuay Screw Compressor
Thanks for the input guys. I spoke to the client about the risks and he's elected not to pursue this, - which I think is wise. Tony's office looks like the lab of a mad scientist. All he needs is some bubbling chemicals and a some rotating governor weights somewhere to make it complete. :D

I would agree with you if it was my office! I have the usual desk and chair like everyone else! I don't know how a compressor test cell got upgraded. By The way, the VFD is a standard option for mcQUAY and pays for itself in about 18 months - your client got the wrong advice.
