Custom and Predesigned Cooling Towers

Design features of counterflow and crossflow cooling towers include guaranteed thermal performance. Other features include computer analysis for optimum design, custom and predesigned sizes, minimum fan horsepower, low pumping head and aesthetic design. With rugged, heavy-duty construction using wood, concrete, steel or fiberglass, the towers are constructed for easy maintenance and through bolted framing.

Evaporative Cooling Tower Systems

Evaporative systems provide cooling below dry bulb ambient temperature. The systems cool by evaporating a small portion (approximately 1.5 percent of flow) of recirculating water. It maintains temperature to within 3°F of wet bulb ambient. According to the company, it saves approximately 97 percent of water compared to tap water systems. Features include a stainless steel indoor sump for freeze protection; stainless steel or fiberglass cooling tower construction; high temperature fill; backup pumps; isolated plant water systems via heat exchanger or closed circuit evaporative tower; filtration; and cooling tower stands.

Cottonwood Filter Screens

Cottonwood filter screens are designed to keep airborne debris such as cottonwood seed, insects, leaves, pollen, paper, construction debris and more out of cooling towers, air-cooled chillers and HVAC systems. Screens are constructed of an engineered, vinyl-coated polyester mesh with a nonstick surface, heavy-duty reinforced binding and industrial-grade fasteners. Filters are cleaned with a broom, brush, shop vacuum or garden hose - even the rain will rinse them clean.

Closed-Circuit Cooling Towers
Induced-draft FXV product line includes single air inlet cells and larger, higher capacity dual air inlet models. Standard design features satisfy environmental concerns, minimize installation costs, maximize year-round operating reliability and simplify maintenance requirements. Thermal performances of all are independently certified by the Cooling Technology Institute (CTI), eliminating the need for onsite field tests. The company’s Combined Flow Technology employs a combination of coil and wet-deck heat transfer surfaces to increase performance. They are designed to ease access for maintenance and offer low sound levels and low operating weights.

Cooling Towers
FRP cooling towers are energy efficient and simple to maintain and service. Other features include light weight, durability, compact size and installation ease. Evaporative cooling allows a small portion of the water being cooled to evaporate into a moving airstream to provide significant cooling to the rest of the water stream. Towers range in size from 5 to 2,000 tons.
