Correct, it's a two stage compressor. And you're close on your temps. The HP hi disch temp trip is at 446 deg. F. Well done. Not sure how to duct an intake but I'll have to go take a closer look at the machine. It would seem to be a conceptually easy thing to do.

Thanks. It's a dry screw, motor driven, 120 psig discharge pressure. I like your idea of lowering the discharge pressure. It gives me something to think about. There is no suction piping - the compressor takes inlet from the surrounding environment (that, plus the forced...
Thanks for your replies. Yes, in fact, we did duct some forced, cooled air to the compressor. The compressor is air cooled, so we ran some duct from a nearby service water heat exchanger to blow cooled air into the machine air intake. We have also removed the side panels (acoustic panels) and...
I work in an industrial facility, and we have a 400 scfm rotary screw air compressor in a very bad (hot) location, such that it runs hot in the summer and has tripped on high HP element discharge temp. Moving the compressor or cooling the local environment would be costly. My question - are...
