Rhoss Chiller
Would anyone have any information on Rhoss Chillers?
It is a YMD TCAEY 260, small Chiller 80KW or so.

The Chiller is running, starting & stopping on demand, but just no idea what that means.

Refrigerant Compliance Guide
I got this EPA Compliance guide from FM hero today, figured it might be useful for some that are working in industrial facilities that need to keep a tight ship with documentation for the EPA.
I also uploaded a copy of it to the member files as well.
Hopefully everyone is having a good new year so far.
