The subject power plant had a counter-flow cooling
tower located in the Chicago area. We first inspected
the tower in February of 2018 and witnessed excessive
icing which was causing damage to the wood structural
members as well as degrading performance.
The customer attempted to install tarps to keep the heat
in the tower and melt the ice. This was a temporary fix,
not custom fitted and had to be removed and reinstalled
on a yearly basis. In December of 2018, Galebreaker
supplied a permanent solution with their retractable
winterization screens which could be deployed in the
winter and retracted back up in the summer.

The tube that the screen is

quickly and easily.
Galebreaker screens are custom manufactured
to fit the specific openings for the customer.
This is the finished product on the
west side of the tower. This is the
side most susceptible to icing.
Another picture of the west side. The icing
on the inside had been melted due to the
retention of heat just inside the screens.
This is a picture of the east side which had all
of the obstructions. A series of (5) different
screens were installed to miss all obstructions.
The project was a huge success with the customer. The cost to install and remove temporary tarps was
eliminated. With temperatures in the high 20’s F, the ice was removed on the structures at the air inlet and the
following benefits realized:
• Improved performance
• No damage to mechanical equipment
• Complete seasonal protection
• Fully retractable operation – quick and easy
The best practice for ice attenuation is proactive operation of the fans. A combination of proper fan operation
and deployment of Galebreaker Screens will help you operate your tower safely and prolong the life of your
cooling tower structure.
Galebreaker provide both temporary and permanent solutions:
• Up to 64m wide (210ft) and 6m high (20ft)
