The Marley MD is a factory-assembled, counterflow cooling tower. For many HVAC and light industrial applications, this design requires less plan area and offers greater site placement flexibility than a comparable crossflow cooling tower. A broader box size selection and more design options have expanded the range of the versatile MD product line. New selections with anti-fouling film-type fill expand the MD’s applications to include process water with high solids content.

Back-to-back installation configurations for all models provide even more site placement adaptability. Optional mechanical access platforms are now available, whether factory assembled or field installed, that allow safe access to the mechanical system, water distribution system, fill and drift eliminators. The Marley MD is a CTI-certified, fully rated cooling tower for a wide range of flow and temperature requirements.

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

Smaller Footprint
Induced-draft counterflow cooling tower design requires less plan area than crossflow cooling towers for many HVAC and light industrial duties. And because the cooling tower’s size typically results in less steel used, its reduced weight requires less support structure.

Low Energy Consumption
Induced-draft counterflow mechanical equipment minimizes the energy consumption by providing a lower fan energy requirement than centrifugal fan counterflow cooling towers.

Ease of Maintenance
SPX Cooling Technologies has worked hard to address the maintenance difficulties long associated with counterflow cooling towers. Our MD cooling tower provides larger access doors, easily removable block fill and other features that simplify maintenance.

Low Sound
The CTI-certified Marley MD cooling tower comes standard with our low-sound fan, suitable for most noise-sensitive situations. Multiple fan and attenuation options are available to meet more stringent sound requirements.

Independently Validated Sound Data
Marley towers are the only package cooling towers tested per CTI ATC-128 test code by third-party CTI-licensed test agents and certified acoustical engineers. MD sound levels are independently verified to meet published sound levels.

Superior Water Management
To address the “splash-out” problem typically found in other manufacturers’ counterflow cooling tower designs, SPX introduces an industry first: a triple-pass inlet louver that conserves water and improves winter operation. 

FM Approval
For applications of two or more cells, the MD tower conforms to the FM Approval Standard for cooling towers, Class Number 4930.
