How a Glycol Feed System Works
A glycol feed system automatically monitors and maintains fluid levels within a closed-loop system. When pressure drops due to fluid loss, maintenance activities, or system expansion and contraction, the feed system introduces additional glycol solution or water to restore proper operating conditions.
By maintaining consistent pressure and fluid volume, the system helps improve efficiency, reduce corrosion risks, and protect valuable HVAC and process equipment.
