Well in case anyone was wondering what was up...I'm having pump problems.
What kind of pumps work @ -30c........what do people use successfully on these chillers? Thanks...I'm pulling my hair out here.
Diaphragm pumps have rubber diaphragms which are hardened by the cold and then don't work correctly. Impeller pumps are way too loud. I'm thinking people must use piston pumps.....
........any info would be great.
