Descripción general

The Marley DT Fluid Cooler is an induced-draft counterflow cooler. Its closed-circuit design keeps the process fluid in a clean closed loop. The fluid is cooled by recirculating water that flows over the outside of the heat transfer coils. Because the DT Fluid Cooler does not contain heat transfer fill media, it offers greater dry operation flexibility in cold weather than fill/coil hybrid coolers. Optional finned coil models expand dry cooling capacity to a wider range of ambient temperatures versus standard bare tube coils. Other advantages include fewer components than open tower and plate heat exchanger (PHE) systems and lower fan energy costs compared to forced-draft coolers.

Broad Product Selection 
Choose from DT models in a wide range of box sizes – from 8.5 x 9 feet to 12 x 18 feet, or 2.6 x 2.9 meers to 3.7 x 5.5 meters – and with bare tube coil or finned coil to meet your specific cooling requirements.

Robust Construction
Strong galvanized steel houses high-quality mechanical and heat transfer systems. Stainless steel component options, including water collection basin and bare tube heat transfer coils, allow customization to address the most demanding environmental conditions and extend service life.

Marley Geareducer® Drive
Genuine Marley mechanical system offers reliability and low maintenance, including a 5-year warranty. Belt drive option is also available.

PVC Louvers
Triple-pass inlet louvers control splash-out and sunlight exposure to the collection basin, limiting potential for algae growth. The PVC louvers also offer easy access to the collection basin from all sides.

Clog-Resistant Water Distribution System
Self-draining spray headers and large 1-7/8” orifice spray nozzles help prevent debris build-up and clogging. Self-draining spray headers deter potential icing.

High Efficiency Axial Fan
Adjustable pitch fan blades permit the maximum utilization of rated horsepower and optimal cooling tower performance.

Premium Efficiency Fan Motor
The TEFC 1.15 service factor motor is designed to Marley specifications and specially insulated for humid cooling tower conditions.

PVC Drift Eliminators
High-efficiency, triple-pass PVC eliminators limit drift losses and are easily removed for inspection.

Large Access Door
Door provides convenient access to mechanical system, drift eliminators, water distribution system and heat transfer coils.

Sound Reduction
The CTI-certified DT Fluid Cooler comes standard with a Marley low-sound fan. Multiple fan and attenuation options are available to meet more stringent sound reduction requirements.

Marley Reliability
Heavy-duty construction, high-performance design and our five-year mechanical warranty ensure consistent cooling over a wide range of flow and temperature requirements.

Operation

Process fluid is pumped internally through the coils.

Recirculating water is pumped from the collection basin to the pressurized distribution system and is evenly distributed over the coils.

Heat is transferred from the process fluid to the recirculating water as it flows over the outside of the heat transfer coils.

Air induced through the fluid cooler evaporates a small portion of the recirculating water, rejecting heat to the atmosphere.
