How a High-Temperature Glycol Feed System Works
A high-temperature glycol feed system automatically monitors pressure within a closed-loop system and supplies additional fluid whenever pressure falls below the required operating range. This helps compensate for minor fluid losses, thermal expansion fluctuations, maintenance activities, and other factors that can affect system performance.
By maintaining proper fluid volume and pressure, operators can improve efficiency, reduce maintenance issues, and extend the service life of critical equipment.
