Freeze glycol protection in closed loop systemsWith another big freeze due this winter, now is the time to start protecting your water systems. You may already have glycol (antifreeze) added to your closed loop systems, however as may found to their peril last year in the freezing conditions in Scotland, it is essential to check that the glycol levels are sufficient within the system to withstand the forecast temperature drops.

At HBE, we recommend that your system has a minimum of 10% glycol which will protect you to a temperature of -5C, however with the freezing conditions forecast, dependent upon your situation, we would suggest you consider protecting your system to -15C.

At HBE, we can help you with the following:

  • Initial surveys of closed loop systems to determine the water chemistry and from that decide on an appropriate plan of action;
  • Supply of both propylene & monoethylene glycol;
  • Dosing the chemical into the system.

If you require any further information or help, please contact your local HBE office or email info@hberm.com
