Gly-pak Industrial Glycol Feed System

The Gly-pak glycol feed system is used to automatically feed a glycol mixture into closed loop piping used in HVAC chill water and hot water recirculation systems. The glycol feeder is activated when it's internal pressure sensor indicates a low pressure condition. A gear pump feeds the glycol solution into the attached system piping until normal pressure is achieved. Optionally dry contacts will be activated on pump start or low level to indicate an alarm condition exists. We suggest that the dry contacts be connected the building management system and alert personnel that the glycol feed system is active indicating there may be an abnormal leak in the system. Several models are available and can be customized to fit any application.
