An induced-draft counterflow unit, the SPX Cooling Technologies Marley DT evaporative fluid cooler has a closed-circuit design that keeps the process fluid in a clean, closed loop. The fluid is cooled as air induced through the unit evaporates a small portion of the recirculating water, and heat is rejected into the atmosphere. The cooler features galvanized steel construction. Stainless steel component options, including heat transfer coils and a water collection basin, are available.
