SPX Cooling Technologies, Inc. has introduced its new Marley LW Fluid Cooler, an induced-draft counterflow closed-circuit fluid cooler. The company said the new fluid cooler design incorporates patent-pending heat transfer technology, a lower height to address local code restrictions, and other significant installation and maintenance advantages.

The Marley LW Fluid Cooler is a closed-circuit design which keeps the process fluid in a clean closed loop. Copper heat transfer coils offer corrosion resistance and greater thermal efficiency which contribute to the LW’s compact equipment size, lower weight, and long service life. The copper coils are also bacteriostatic, recyclable, and require less process fluid volume.

With standard unit heights less than 10.5 ft, the Marley LW Fluid Cooler meets many code height requirements and offers advantages for rooftop installations where low visibility is important. Other significant installation advantages include single-piece installation, single-point power connection, factory-installed controls, and factory wiring and testing. Operational benefits include electronically commutated (EC) direct drive fans requiring no routine maintenance, a low-clog spray system, and multiple doors that allow access to interior components without tools.

The Marley LW Fluid Cooler is well-suited for HVAC applications, including water-source heat pumps for commercial buildings and multi-unit residential high-rises, water-cooled VRF, and skid-mounted systems. It is also a fit for industrial applications such as compressor, machine jacket, and special fluid cooling. The Marley LW Fluid Cooler is a viable option for specifications calling out heat rejection duties less than 200 tons, counterflow fluid coolers, outdoor forced-draft fluid cooler replacement, lower height or weight requirements, or redundancy restrictions.

Nominal footprints available include 4-ft by 12-ft and 8-ft by 12-ft, with cooling capacity ranging from 34 to 107 nominal tons and flow ranges from 40 to 1,200 gpm per cell. Multiple coil configurations are available.
