Calculator
Good morning and Happy New Year everyone. As a temperature control tech for a major rental company I was wondering if anyone had a good resource for pipe loss and/or system calculations. I have not found any good apps as of yet.

30HXC Screw Compressor Terminals
We’re tasked with replacing all terminals and studs in the terminal box for a Carlyle screw compressor model 06NW2209X7NA.A00. We’re doing this because someone found leaks here.
