SPX Cooling Technologies, designer and manufacturer of evaporative and air-cooled heat exchangers, has released the new Marley LW, an induced-draft counterflow closed-circuit fluid cooler.

The new fluid cooler design incorporates patent-pending heat transfer technology, a lower height to address local code restrictions, and other installation and maintenance advantages.

The Marley LW 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 10.5ft, the Marley LW 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 is well-suited for heating, ventilation and air conditioning (HVAC) applications, including water-source heat pumps for commercial buildings and multi-unit residential high-rises, water-cooled variable refrigerant flow (VRF), and skid-mounted systems.

It is also a good fit for industrial applications such as compressor, machine jacket, and special fluid cooling.

The Marley LW is a viable option for specifications calling out heat rejection duties less than 200 tonnes, counterflow fluid coolers, outdoor forced-draft fluid cooler replacement, lower height or weight requirements, or redundancy restrictions.

Nominal footprints available include 4x12ft and 8x12ft, with cooling capacity ranging from 34 to 107 nominal tonnes and flow ranges from 40 to 1200gpm per cell.

Multiple coil configurations are available, and the thermal performance of the Marley LW is certified by the Cooling Technologies Institute (CTI).
