Evaporative cooling towers are one of the best long-term solutions for industrial cooling challenges. They offer advantages when compared to a dry cooler, notes one manufacturer. In a white paper, Gary Dicker, the director of DHD Cooling, offers his view on the two cooling technologies.

Evaporative cooling has been around for centuries. Also called adiabatic cooling (particularly in Europe), evaporative cooling is the earliest form of air-side cooling known to man. In spite of that, it also is probably the least understood — and sometimes maligned — solution to cooling.

The evaporative cooling industry delivers savings in terms of CO₂ emissions — now and in the future — an advantage over dry cooling alternatives.

Several global trends are contributing to the desire for cooling system solutions that can help companies use less energy and water for cooling. Heavy flooding in some regions, drought conditions in others, and extreme temperatures and weather events help drive the demand for such solutions.

Hot oil refineries and other industrial facilities can present hazards for process cooling equipment and personnel, creating hazardous working conditions. 

When treating wastewater, sludge and digestate, it often can be beneficial to reduce the volume of material or increase the solids content as well. Mechanical dewatering via a centrifuge or belt press — to separate solids and liquids — is standard for the water treatment and anaerobic digestion sectors. 

Water Saver utilizes capacitive deionization technology to reduce dissolved ion concentration, thus lowering the makeup water conductivity prior to use in an evaporative cooling system. 

Industrial buildings are good candidates for evaporative cooling. The facilities are typically quite large — with tens of thousands of square feet — and often have high roof structures (more than 30 feet) to provide crane clearance, manufacturing equipment clearance and racking systems.

Evapoway is designed to help companies with the evaporation of frost and condensate where no drain is available or practical. The electric condensate evaporators have passed rigorous testing and are UL recognized.
