Engineered Evaporative Fluid Coolers and Vapor Condensers by Niagara

(Buffalo, NY) Niagara Blower Heat Transfer Solutions provides engineered solutions to heat transfer applications using Wet Surface Air Cooler (WSAC(TM)) closed-loop, evaporative coolers and condensers. These WSAC systems combine elements of a tubular heat exchanger and cooling tower in a single structure and are a cost-effective heat transfer technology providing lower outlet temperatures and requiring less space and HP. The WSAC cooler/condenser can also use poor quality water as spray makeup.

Warm process fluids or vapors are cooled in a closed-loop tube bundle. The process fluid being cooled never comes in contact with the environment. Open-loop water is sprayed and air is induced over the tube bundle resulting in the cooling effect.

Each WSAC system is custom designed to fit a specific heat transfer application. Design parameters are based on customer specifications for input and output temperatures as well as average weather conditions. All WSAC units are tailored to meet the unique needs of the most demanding applications in the world. Niagara WSAC coolers and condensers vary in size from smaller packaged skidded to large field-erected units.

Niagara Blower is a design-build manufacturer providing engineered solutions to heat transfer applications at power, process, refinery, food and brewing facilities worldwide since 1904. Niagara's customized product lines include WSAC closed-loop, evaporative coolers and condensers and "No-Frost"® liquid desiccant dehumidification systems.
