Description

This procurement is for a single, self-contained, outdoor-rated 20-ton air-cooled industrial process chiller system complete with an integrated glycol pump and glycol buffer tank system.

The primary function of this equipment is to cool and circulate a 50%/50% propylene glycol/water mixture at a set temperature of 35°F (with a flow rate of 60–90 GPM) to condense and dry water out of a hydrogen stream generated by a proton exchange membrane (PEM) electrolyzer. The system must operate under variable loads and survive extreme ambient outdoor conditions at an elevation of 6,000 feet.
