There’s nothing you can do about ice buildup on your cooling towers. There’s also nothing you can do to avoid icy cooling towers and chillers. Although you cannot prevent the ice, you can manage it better by choosing the right kind of cooling tower components.
Choosing The Right Components Matters
Certain cooling tower components manage ice better than others. Here are some of the cooling tower components that will help you to manage icy weather better.
Choose Induced Draft Cooling Towers Over Forced Draft
Induced draft cooling towers control ice better than forced draft cooling towers because it has a fairly efficient deicing sequence. If ice does form, it runs the axial fan in reverse at half speed in short bursts to minimize the buildup.
Choose A Counter Flow Over Cross Flow
When you compare cross flow technology and counter flow technology, counter flow has the winter weather advantage. It provides a layer of protection from the winter weather, because the heat transfer media in counter flow towers is totally encased within the unit. Cross flow towers have fewer cooling temperature gradient throughout the heat transfer media, whereas counter flow has more, so the water is cooled at a more even rate, which prevents pockets of water from causing condensation and freezing.
Choose VFD Controls Over Two Speed Fan Motors
It’s important to keep the water at an above freezing temperature of about 42°F. Using variable frequency drive controls or VFD controls is the most efficient and flexible capacity control method. The two-speed motor does work reasonably well, but it’s not as efficient.
Choose A Multiple Cell Over A Single Cell
Many cooling systems are designed to run on reduced water in the winter to accommodate the lower heat load in the winter. Water can be diverted from one cell to another, which can mediate uneven eater distribution. Uneven water distribution is more prone to freezing and ice production.
Does The Winter Weather Make You Worry About Your Cooling Towers?
Does the winter weather make you worry about how you’ll manage the ice and snow on your cooling towers? Just making a few adjustments to the components of your cooling tower can save you so much time in the future.
