What is evaporative cooling? From the perspiration on your skin, to the transpiration from the pores on trees, evaporative cooling is found throughout the world; remember those misting fans everyone loved in the 90’s? That’s evaporative cooling too. Evaporative cooling is the process in which the evaporation of water removes heat from a system. Application in cooling towers Cooling and HVAC units typically use evaporative cooling through either counterflow or crossflow systems, this can be further broken down to direct and indirect evaporative cooling. Counterflow In counterflow systems, water

One of EVAPCO’s greatest innovations, CrossCool is a method of internally enhancing elliptical tubing to increase the capacity of closed circuit coolers, evaporators, and evaporative condensers. The grooves inside the tube increase the fluid turbulence, increasing the rate of heat exchange and thus the capacity of the unit. Giving the edge in ammonia refrigeration CrossCool optimizes performance in evaporators and low-charge ammonia circulators, allowing for equal to greater performance at lower recirculation rates; just another example of EVAPCO reducing customer costs and improving unit

Highlights The most efficient coil design and ONLY fully finned coil available on the market Increases both wet and dry capacity Averages 25% increased efficiency when used in evaporative mode in closed circuit coolers Tightly packed tube design means even greater capacity and efficiency per plan area Product Features EVAPCO’s Most Advanced Coil Design The most advanced cooling coil in the industry, the patent pending Ellipti-fin coil heat transfer technology assures even greater operating efficiency, with studies showing a 20% increase in capacity for closed circuit coolers over the EVAPCO’s
