Glycol Management System
The CALMAC Glycol Management System (GMS) is designed to maintain the proper volume of coolant in a building circulating loop by monitoring the system's pressure and adding fluid from a reservoir to the system when the pressure drops below a set point.
Features include:
- Unit is able to be located outdoors with TEFC pump motor, hot dipped galvanized frame and a NEMA 3R control box.
- A 65 gallon vented reservoir, with 10 gallon graduations which can be used for mixing glycol/water solution.
- Alarms to indicate various conditions, which are detailed below.
- Pressure relief valve which protects against over-pressurization by the GMS. Not to be used in place of a properly sized system pressure relief valve.
- Check valve between building system and GMS.
- Service valve between the reservoir and the pump.
- Drain valve located after pump to allow removing most of solution from the GMS reservoir.
Add Solution warning. Solution needs to be added to the reservoir, however GMS pump will continue to run until level reaches the Low Liquid Level alarm.
Low Liquid Level. GMS pump is automatically turned off.
High Liquid Level.
Low System Pressure. Possible leak in building system.
Loss of Power. Low Liquid Level alarm contacts also close on loss of power.
