Maziak's tips to winterising your process cooling equipment

Maziak's winterisation tips can help you get your external chillers, free coolers, and adiabatic coolers ready for the winter season! 

Now that winter has arrived, it's time to get your adiabatic coolers, free coolers, and external chillers ready for the upcoming chilly months.

You must winterise them as soon as the temperatures start to fall if you want to keep them from being harmed by the cold.

Here are a few short ways to make sure your chillers and coolers survive the winter safely and are in perfect working order for the next year.

Tip 1: Turn off the mains cold water supply and drain the adiabatic water supply 

To get your adiabatic cooler protected for winter, you’ll need to first turn off the adiabatic pad distribution system and drain the water supply to the cooler, completely draining/flushing out any remaining water in the lines.

Tip 2: Check glycol levels

We recommend the concentration of glycol in your process water system should be at 30%. This concentration will provide you with protection at temperatures down to -15°C – this can be checked with a refractometer. 

Tip 3: Do not leave untreated water in coolers or chillers over winter shutdown

When water turns into ice, it expands by 9%. As a result of this, unprotected copper pipes which contain water without the correct 30% concentration of glycol in them can split, resulting in unnecessary and expensive damage to your chillers and coolers. Also, when the temperature increases and the ice thaws, costly water leaks will follow.
