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.

Patented* EVAPAK® Fill

The patented EVAPAK® fill design used in the UBT Cooling Tower is specially designed to induce highly turbulent mixing of the air and water for superior heat transfer. Special drainage tips allow high water loadings without excessive pressure drop. The fill is constructed of inert polyvinyl chloride, (PVC). It will not rot or decay and is formulated to withstand water temperatures of 130ºF (54,4ºC). Because of the unique way in which the crossfluted sheets are bonded together, and the bottom support of the fill section, the structural integrity of the fill is greatly enhanced, making the fill usable as a working platform. The fill selected for the Cooling Tower has excellent fire resistant qualities. Cooling Tower fill has a flame spread rating of 5 per ASTM-E84-81a. A higher temperature fill is available for water temperatures exceeding 130ºF (54,4ºC). Consult your EVAPCO representative for further details. *U.S. Patent No. 5,124,087
