In extreme subfreezing conditions, the coil of your evaporative fluid cooler can freeze up. When this occurs the coil needs to be replaced.
Don't let this happen ! Make sure you take appropriate actions to prevent coil freezing.
How do you prevent the coil from freezing?
- Make sure the glycol concentration in your closed loop system is still adequate for today's extreme outside temperatures.
- If your system doesn't contain glycol, check your control sequence and settings to maintain the minimum recommended flow, so the temperature of the circulating fluid will not be below 7°C.
- If your unit is equipped with closure dampers, control their operation and make sure they are closed when the unit is idle.
- Read more on how to protect evaporative cooling equipment for cold weather operation in Chapter 19 (item 16) of our Application guidelines.
