An induced-draft, coil only closed-circuit cooling tower, the Marley® DT Fluid Cooler with Aero-X™ coil technology provides dry operation flexibility that fill/coil hybrid coolers cannot.

​

Aero-X Coil Technology Maximizes Thermal Capacity Per Footprint*
The lowest air-side pressure drop (up to 10% more airflow at the same fan HP) and highest nominal heat rejection capacity per footprint – benefits realized with the DT Fluid Cooler’s Aero-X coil technology – provide opportunities to reduce equipment size and/or lower energy consumption, while maintaining the dry operation flexibility that coil-only closed circuit coolers are known for.

​

Higher Dry Switch Point – Up To 10F+ Higher*
Whether the motivation for seasonal dry operation is to reduce site water usage, minimize water treatment costs or simplify operation in freezing conditions, higher dry switch point temperatures enable achievement of those objectives a larger portion of the year. With up to 10°F + higher dry switch point, the DT Fluid Cooler may enable up to 15-20% incremental annual hours in dry mode. Annual water savings per cooling ton of 3,000 gallons/ton and $40/ton are achievable in many areas, depending on climate conditions. Optional finned coils further enhance dry operation capability at higher ambient temperatures.

​

Lower Fluid Pressure Drop – Up To 30%
Reduced pumping energy requirements compared to the previous generation positively impact system operating cost and energy consumption.

​

Finned Coil Option – Now with Aero-X Coil Technology!
Optional Aero-X finned coil further enhances dry operation capability at higher ambient temperatures and boosts evaporative performance. Offers up to 20°F higher dry bulb switch point and up to 30% evaporative performance increase compared to similar bare-tube coil models.
