How a High Temperature Glycol Feed System Works

A glycol feed system continuously monitors pressure within a closed-loop heating system. When fluid loss or pressure reduction occurs, the feed unit automatically introduces additional glycol solution to restore proper operating conditions.

This automated process helps reduce manual intervention, maintain system efficiency, and protect equipment from damage caused by insufficient fluid levels or pressure fluctuations.
