All NC Class cooling towers are designed for low sound levels using high blade-count, wide-chord fans for maximum efficiency at low tip speeds. For those extreme, low sound applications, consider the NC Class low sound “L” models. To achieve the very lowest possible sound levels while maintaining efficiency, “L” models are carefully selected with the best available combination of motor, drive ratio, fan blade-count and blade profile.

Q u i e t b y D e s i g n

High Efficiency Axial Fan

Adjustable-pitch fan blades permit maximum utilization of rated horsepower—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.

Marley 2400 Geareducer

SofTork Coupling

Absorbs excessive shock loads at start-up—forgives minor misalignment between the motor and Geareducer.

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.

Marley NC Class specifications

SPX Cooling Technologies is renowned for its innovative and high-performance cooling solutions, with the Marley NC Class cooling towers standing out as a hallmark of engineering excellence. Designed to meet the rigorous demands of diverse industrial applications, the Marley NC Class combines advanced technologies with efficiency and durability.

One of the key features of the Marley NC Class cooling towers is their innovative design. The tower is engineered with a counterflow configuration that maximizes cooling performance while minimizing space requirements. This design allows for efficient airflow and water distribution, leading to optimal thermal performance even under varying load conditions. The ability to operate effectively in tight spaces makes the Marley NC Class an ideal choice for facilities where footprint is a constraint.

Durability is another hallmark of the Marley NC Class. Constructed with high-quality materials, including fiberglass reinforced plastic (FRP) and stainless steel, these cooling towers are built to withstand harsh environments and corrosive conditions. The use of these materials not only enhances longevity but also reduces maintenance costs over time. The Marley NC Class is designed for long-term reliability, ensuring minimal downtime for industrial operations.

The Marley NC Class also integrates advanced technologies that further enhance its efficiency. A notable feature is the use of advanced fill media, which optimizes heat transfer while minimizing pressure drop. The proprietary film fill technology increases surface area for heat exchange, facilitating better cooling performance. Additionally, the towers come with customizable options for fan types, ranging from efficient axial fans to quiet and energy-efficient centrifugal fans, allowing users to select configurations that suit their operational needs.

Energy efficiency is a critical consideration for many industries today. The Marley NC Class addresses this need through its smart design and technology. By optimizing airflow and water distribution, the cooling towers are capable of significant energy savings, which can lead to reduced operational costs. Furthermore, they can be equipped with variable speed drives (VSD) for fans, allowing for real-time adjustments based on cooling load requirements, thus enhancing energy efficiency even further.

In summary, the Marley NC Class cooling towers by SPX Cooling Technologies represent a fusion of advanced engineering, durability, and energy efficiency. With their innovative design, high-quality construction, and state-of-the-art technologies, they are perfectly suited for a range of industrial applications, helping businesses achieve optimal cooling performance while minimizing their environmental footprint. The Marley NC Class stands as a reliable and efficient solution, catering to the evolving needs of industries in a competitive landscape.
