How to Deal With and Prevent HVAC Coils from Freezing

As the seasons change from fall to winter and cooler weather settles in, many facilities are gearing up for winterizing their facilities. Preparing your facility for winter can mean many things depending on who you ask. Today, we’re talking about preparing your HVAC coils for winter.

When we ask facilities folks and maintenance personnel how they deal with and prevent coils from freezing, some have told us the have a solution: they drain their coils, fill them with glycol, then drain the coil. This “solution” can take several man-hours per coil and is not fool proof – there is a better way!

Some others use a freeze pump, monitoring the leaving water temperature of the coils and circulating water when that water temperature gets too low. This wastes energy and is also not fool proof. There is a better way!

Cooney Freeze Block coils don’t damage from freezing. If a Cooney Freeze Block coil senses low temperature or building pressure inside the coil, a pressure relief valve opens, draining a controlled amount of fluid from the coil. When the temperature goes up or the pressure goes down, the valve reseats. This means you’ll never have to replace another coil due to freeze damage again.

Flow Tech has several resources available, including a video from Cooney and a video showing the splash tank in our Demo Lab. Better yet, come visit us in the Demo Lab to talk about Cooney Freeze Block coils and all our other HVAC equipment. We’ll even buy you lunch!
