The QuadraFlow’s unique, compact design is matched by its performance, maintainability, and reliability. This cooling tower makes use of inert, non-corroding construction materials that operate in all seasons and in a wide variety of environments. The QuadraFlow cooling tower is factory-fabricated and is designed to be assembled at the jobsite.

Supporting steel— simplifies foundation requirements.

Quality Parts
High Efficiency Axial Fan— Adjustable-pitch fan blades permit maximum utilization of rated horsepower and allows field adjustments to optimize tower performance.
System 5 Geareducer— The Geareducer option requires no oil changes for five full years — the lowest maintenance requirements in the industry. Reduced waste stream and environmental impact. Independent testing has proven a Marley Geareducer is up to 4 dBA quieter than the gearboxes used by most other cooling tower manufacturers.
Fan Motor— TEFC 1.15 service factor, horizontal-shaft motor designed to Marley specifications for cooling tower duty. Specially insulated for humid cooling tower service.
Five-Year Mechanical Warranty— Five-year total mechanical equipment warranty including mechanical equipment support, plus our exclusive 5-year maintenance-free System 5 Geareducer.

Popular Options
Inlet Water Bypass— provision for total water bypass directly into the cooling tower collection basin during cold weather operation.
Hoistable Steel Grillage— allows assembling cooling tower at grade on temporary supports and hoisting into final location.
Fire Retardant FRP— flame spread rating of 25 or less per ASTM E-84.
Control Systems— ranging in sophistication from standard fan starters and disconnects to Programmable Logic Controllers that work in conjunction with your building or process system.
Variable Speed Drive— the ultimate in temperature control, energy management, and mechanical equipment longevity.
Electric Basin Heater Package— maintains collection basin water temperatures between 40°F and 45°F during tower shutdown.
Vibration Limit Switch— shuts down the fan motor if excessive vibration occurs.
Solid State Water Level Control Package— monitor basin water level with solenoid-valve water makeup. Configurations include makeup along with high and low water level alarm and cutoff and electric basin heater cutoff.
Magnetrol® Electric Float Switch— monitor basin water level with solenoid-valve water makeup.”


“Long Life Construction
The QuadraFlow cooling tower is built with corrosion-proof materials for reliability in severe operating environments. It is warranted for five full years, which includes the fill, mechanical equipment, and structure.
Low Operating Costs
Marley’s high-efficiency fill and fans, gravity-flow water distribution, and efficient Geareducer® work together to offer maximum cooling with minimum power use.

All Season Performance
Performs as specified in the heat of summer — responds well to energy-management techniques in the spring and autumn — operates virtually ice-free in the dead of winter — and offers simple maintenance all year long.”
