Unilite

The Ceramic Unilte counterflow cooling tower has proven itself as one of the most efficient and reliable designs ever. The Unilite is a proven design, making use of pultruded fiberglass shapes as structural members. FM approval available.

Proven through years of successful chemical plant construction, pultruded fiberglass is ideal for the wet, corrosive cooling tower environment. It’s strong like steel but at a fraction of the weight. Yet, it will not corrode from chemical exposure or moisture, and it resists deterioration from sunlight.

reflex rtm fan cylinder

A light RTM (resin transfer molding) closed-molding process lends itself to increased durability for the final product, and ensures laminate thickness and weight consistency. Because the cavities are infused using rigid forms in the ribs, there is no porosity or potential sites for delamination or structural fracture to begin. Therefore, the cylinder load capacity is greatly enhanced.

plume abatement

Let’s Clear the Air… For decades, cooling towers’ cold-weather condensation plumes have been a major problem. At best, they’re unsightly; at worst, they impair visibility and waste water. Which make them a particular worry around airports and other environmentally sensitive areas.

At SPX Cooling Technologies, we’ve made it our mission to eradicate as much of the plume as possible – while conserving significant amounts of water along the way.  And we’ve succeeded.
