CALMAC™ Glycol Management System

Overview

Cooling management simplified.

Maintaining the proper coolant volume in your building's circulating loop is crucial for ideal temperature and efficiency. The CALMAC Glycol Management System (GMS) adds fluid from a reservoir when pressure drops, keeping system pressure and performance at their best without constant monitoring.

  • 65-gallon reservoir
  • 10-gallon graduations for easier solution mixing
  • Enhanced valves placement throughout the system for service
  • Easy -alert system keeps facilities team informed
  • Constructed for indoor or outdoor installation
  1. Stay Informed with Monitoring Alerts

    The CALMAC Glycol Management System provides the facilities team with alerts:

    • Add Solution Warning (solution needed in reservoir)
    • Low Liquid Level (system turns off until refilled)
    • High Liquid Level (high liquid in reservoir)
    • Low System Pressure (possible leak)
    • Loss of Power - Low Li
  2. Install Indoors or Outdoors

    The unit can be located indoors or outdoors thanks to a TEFC pump motor, hot dipped galvanized frame and a NEMA 3R control box.

  3. Get Up and Running Faster

    A large 65-gallon vented reservoir features 10-gallon graduations which can be used for mixing glycol/water solution, helping to reduce labor costs and time. Installation only requires piping to the system, electrical service, and connection. If applicable, tie into the Building Automation Systems (BAS).

Product Information

  • Extends system performance and reduces downtime.
  • Maintains proper amount of coolant to extend life of the system can reduce downtime.
  • A pressure relief valve protects against over-pressurization by the Glycol Management System. (Although it is not to be used in place of a properly sized system pressure relief valve.)
  • A drain valve is located after the pump to allow removing most of the solution from the Glycol Management System reservoir.
  • The check valve is conveniently located between the building system and the Glycol Management System.
  • A service valve can be found conveniently located between the reservoir and the pump.

FAQs

Your questions about glycol management, answered.

A glycol system is a cooling management system that uses a glycol solution (a mixture of glycol and water) as the coolant. The system helps maintain the proper volume of coolant in the building's circulating loop to keep the temperature range within desired limits and maintain operating efficiency. The CALMAC™ Glycol Management System (GMS) is an example of such a system, designed to automatically add fluid from a reservoir to the system when the pressure drops below a set point.

Glycol cooling systems work by circulating a glycol solution through a building’s cooling loop. The glycol solution absorbs heat from the building and transfers it to a cooling unit, which then dissipates the heat. The CALMAC Glycol Management System helps maintain the system pressure by adding glycol solution from a reservoir when the pressure drops below a set point. This keeps the system supplied with the proper amount of coolant to operate efficiently.

Glycol is used in cooling systems for several reasons:

  1. Freeze Protection: Glycol lowers the freezing point of the coolant, preventing the system from freezing in cold temperatures.
  2. Corrosion Inhibition: Glycol solutions often contain inhibitors that protect the system's components from corrosion.
  3. Heat Transfer Efficiency: Glycol has good heat transfer properties, making it effective for cooling applications.
  4. Extended System Life: Properly maintained glycol systems can extend the life of the cooling system by preventing issues related to freezing and corrosion.

A glycol feeder, like the CALMAC Glycol Management System, works by automatically adding glycol solution to the cooling system when the pressure drops below a set point. The system includes a reservoir that holds the glycol solution, and a pump that transfers the solution to the cooling loop. Key features of the CALMAC Glycol Management System include:

  • A 65-gallon reservoir with 10-gallon graduations for easier solution mixing.
  • Enhanced valve placement for easier service.
  • Alerts to keep the facilities team informed about the system status, such as Add Solution Warning, Low Liquid Level, High Liquid Level, Low System Pressure, and Loss of Power - Low Liquid Level Alarm.
  • A pressure relief valve to protect against over-pressurization.
  • A drain valve for removing most of the solution from the reservoir.
  • Check and service valves for convenient maintenance.

The system can be installed indoors or outdoors and is designed for easy monitoring and maintenance, keeping the cooling system operating efficiently and reliably.
