The GMS (Glycol Management System) is an automated system designed to monitor and maintain the pressure in a closed-loop circulating system, says the company. The system automatically adds glycol and water to a pressurized system. It is said to provide a cost-effective solution to the problems involved in maintaining system operating pressures at optimum levels by automatic additions of fluid from a reservoir activated by multi-setpoint pressure switches. The pre-packaged system is suitable for managing a range of pressurized liquids, the company says.
