Two pass design that minimizes splash-out and the potential for algae formation inside the tower.Superior Air Inlet Louver and Screen Design Constructed of an inert polyvinyl chloride (PVC).Reduces water loss during wet operation.Limits the drift rate to less than 0.001% of the recirculating water rate.Available in type 304 SS or type 316 SS construction.CrossCool Internal Tube Enhancement increase fluid turbulence providing additional evaporative capacity.Coil located in airstream increasing dry bulb switchover temperature.Elliptical return bends allows for more circuits per coil bundle increasing the maximum capacity per footprint.A special coil design is utilized to reduce the air pressure drop through the unit while maximizing tube surface area and increasing its heat transfer capabilities. The airflow through the coil is counterflow to the fluid flow, providing the most efficient heat transfer process. EVAPCO's Thermal-Pak II coils patented design assures maximum cooling capacity.
