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\u2019s applications to include process water with high solids content.<\/p>\n Back-to-back installation configurations for all models<\/strong> provide even more site placement adaptability. Optional mechanical access platforms are now available, whether factory assembled or field installed, that allow safe access<\/strong> to the mechanical system, water distribution system, fill and drift eliminators. The Marley MD is CTI Thermal and Sound certified which ensures a wide range of flow, temperature, and sound requirements.[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.16″

perfect fit. In addition to taking up less site space, counterflow cooling towers may have a lower installed weight. Plus, piping costs can be reduced because a single inlet is usually standard. Triple-pass inlet louvers limit the sunlight entering the collection basin to reduce the potential for algae growth. Counterflow cooling towers offer easy access to the collection basin from all sides. The wet surface is totally enclosed for protection from environmental elements, and the MD cooling tower utilizes a corrosion-resistant spray system.<\/p>\n Unmatched Reliability<\/strong> Smaller Footprint<\/strong> Low Energy Consumption<\/strong> Ease of Maintenance<\/strong> Low Sound<\/strong> Independently Validated Sound Data<\/strong> Superior Water Management<\/strong> FM Approval<\/strong> What is a cooling tower?<\/strong><\/a>[\/et_pb_tab][et_pb_tab title=”Features” _builder_version=”4.16″ body_font=”||||||||” body_font_size=”16px” body_line_height=”1.8em” tab_font=”||||||||” global_colors_info=”{}”]AIR MOVEMENT PACKAGE<\/span><\/strong> Eased inlet fan cylinder <\/strong>ensures full-area, low-turbulent airflow through the cylinder.<\/p>\n Spherical roller bearings<\/strong> are rated at an L10 life of 100,000 hours.<\/p>\n TEFC Fan Motor<\/strong> with a 1.15 service factor, variable torque and special insulation for cooling tower duty extends life cycle.<\/p>\n The MD air movement package<\/strong> including structural support is guaranteed against failure for five years.<\/p>\n WATER DISTRIBUTION SYSTEM<\/span><\/strong> Low-clog<\/strong> polypropylene nozzles deliver precise distribution of water over the fill area.<\/p>\n Marley MC<\/strong> thermoformed PVC film fill assembled into packs for easy removal and cleaning.

\nHeavy-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.<\/p>\n
\nInduced-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\u2019s size typically results in less steel used, its reduced weight requires less support structure.<\/p>\n
\nInduced-draft counterflow mechanical equipment minimizes the energy consumption by providing a lower fan energy requirement than centrifugal fan counterflow cooling towers.<\/p>\n
\nSPX 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.<\/p>\n
\nThe 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.<\/p>\n
\nMarley towers are the\u00a0<\/span>only package cooling towers<\/strong>\u00a0<\/span>tested per CTI ATC-128 test code by third-party CTI-licensed test agents and certified acoustical engineers. MD sound levels are\u00a0<\/span>independently verified<\/strong>\u00a0<\/span>to meet published sound levels.<\/p>\n
\nTo address the \u201csplash-out\u201d problem typically found in other manufacturers\u2019 counterflow cooling tower designs, SPX introduces an industry first: a triple-pass inlet louver that conserves water and improves winter operation.<\/p>\n
\nFor applications of two or more cells, the MD tower conforms to the FM Approval Standard for cooling towers, Class Number 4930.<\/p>\n
\nHigh efficiency fan <\/strong>has wide-chord design for maximum efficiency at low fan tip speeds.<\/p>\n
\nPressurized spray system<\/strong> distributes water evenly over the fill.<\/p>\n
\nInduced-draft counterflow<\/strong> design may require less plan area than crossflow cooling towers typically use.<\/p>\n
\nMarley System 5 Geareducer drive<\/strong> <\/span>\u2013 Requires no oil changes for five full years, the lowest maintenance requirements in the industry. Fewer oil changes reduce waste stream and environmental impact. Independent tests prove Marley Geareducer is up to 12 dBA quieter than gearboxes used by other cooling tower manufacturers.<\/p>\n![\"MD](\"\/wp-content\/uploads\/AMU-MD-21A-pdf-image-300x232.jpg\")
