Compressors are very hard to source from the internet. Manufacturing bases in Europe are remote from the head offices, again often in Europe. On Monday last; I was talking to the Howden man in Australia who openly admitted he had no idea what was available from the factory in Scotland.

Atlas Copco used to show a neat little 3 stage centrifugal unit but they hide it from buyers like it had just contracted ecoli.

Mind you; a turbocompressor is not the same thing as a centrifugal compressor; it draws air from a tapping in the 3rd or 4th stage turbine casing on a gas turbine. These are big units: GEC, Siemens & Solar manufacture.

Try LCEC.com (Louisiana Chemical Equipment Company) website for a list of manufacturers' names. They might just have one in stock. ■

Of course I meant impeller casing. It's been one of those weeks. ■

Hello,

The flow rate is definetely well suited for a centrifugal compressor. You may also want to get in touch with a twin stage rotary screw compressor manufacturer to get a quote. Convential wisdom dictates that the two stage dry technology is much more expensive, but it offers usually more flexibility in the trun down rate (if so desrired). ■
