The UBT Cooling Tower product line is an Advanced Technology design with dramatic advancements in structural technology to withstand the greatest forces of nature. Constructed with structural enhancements like heavier gauge steel, increased size and number of fasteners, reinforced mounting flanges and internal cross-bracing, the UBT line can withstand seismic accelerations up to 1.0g horizontal and wind loads of 125 psf. Stone and Webster, using computer modeling and actual proof tests independently certified the seismic and wind load rating of each model. In addition, the counterflow design provides the UBT Cooling Tower with inherently better operational and maintenance features. All of these features are described below.

Pressurized Water Distribution System

The water distribution system is made of schedule 40 PVC pipe and ABS plastic water diffusers for corrosion protection in this key area. The piping is easily removable for cleaning. The water diffusers have a minimum opening of 3/8 by 1 inch (9,5 mm by 25,4 mm) and are practically impossible to clog. They also have an anti-sludge ring extending into the headers to prevent sediment from building up in the diffuser opening .

The spray pressure for all UBT Cooling Towers is between 1 and 6 psig (6,9 and 42 kPa) at the
inlet header. The actual spray pressure will be shown on the certified drawings which are prepared for each unit.
