3 Ways To Protect Your Chillers This Winter!

As winter approaches, ensuring your chiller systems are well-prepared is crucial to prevent damage and maintain uninterrupted operation during the colder months. Follow these three essential steps to keep your chillers functioning efficiently.

1. Check Your Glycol Levels

Maintaining the correct glycol concentration is essential to protect your system from frost damage. Use a refractometer to measure glycol levels, aiming for a minimum of 22%. This not only prevents freezing but also helps to reduce the risk of contaminants forming in your process water.

2. Ensure Chiller Crankcase Heaters Are Functioning

Most external chillers are equipped with crankcase heaters wrapped around the compressors, preventing the compressor body from dropping below a safe temperature. These heaters are vital for protecting compressors from cold-related damage. Remember, do not turn off the electrical supply to your chillers over the Christmas break, as this will disable the heaters and could lead to costly damage.

3. Maintain Power to Circulatory Pumps

To prevent system failures, keep the electrical supply on even when the chiller is not in use. This ensures circulatory pumps remain operational, avoiding disruptions in water flow and preventing safety circuits from triggering. Maintaining consistent operation helps protect the system from unnecessary strain and breakdowns.
