GREEN BOX AMERICA, INC.

Fluid Coolers to replace cooling towers for benefit of plant and planet. Technology provides clean water and in closed-loop to your industrial processes, all year long.

The latest generation of Green Box Fluid Coolers are designed with iC3 Technology, and provide benefits beyond other manufacturers. The Fluid Coolers operate as an air-to-water heat exchanger, a very economical and reliable means of cooling your process water. Several fans, variable speed or staged, match your required cooling needs. The process heat load dictates the rpm of the fluid cooler fans.

During the hottest hours of the summer, Adiabatic Cooling increases the relative humidity of the ambient air. This is achieved by nozzles spraying a fine mist of tap water into the air, on both sides of the fluid cooler. This effect decreases the air temperature before entering the heat exchanger. Hence, the leaving water temperature to your process is below the ambient temperature.

The Adiabatic-SSS Option (Super Spray System) increases the Adiabatic efficiency by using nebulizers.
