3–Raise the hub assembly above the fan shaft for installation. Slowly lower the assembly onto the shaft with the keyways aligned. Make certain the key does not slide down during installation. Stake the key in the keyway with a center punch if necessary.

After the hub assembly is installed the bottom end of the key must extend through the bottom of the center hub, and the top end of the key must extend 5/8(16mm) minimum above the top of the fan shaft. Do not force the key down once these criteria are met.

4–Figure 3 illustrates proper retention plate and hardware installa- tion. The retention plate is designed to allow clearance for the fan shaft key, and when properly installed will not extend over or inter- fere with the key in any way. Torque the retention bolts to 70 ft·lbƒ (95 N·m) then turn up the locking strap corners to prevent the bolts from loosening.

HP700 specifications

SPX Cooling Technologies HP700 is a state-of-the-art cooling tower designed to meet the demanding needs of modern industrial and commercial applications. With its robust construction and innovative design, the HP700 offers reliable performance while minimizing energy consumption and operational costs.

One of the main features of the HP700 is its high-efficiency fan design, which significantly enhances air flow and cooling capacity. The use of advanced aerodynamics in the fan blade design reduces energy consumption while maintaining optimal cooling performance. Additionally, the variable frequency drive (VFD) technology allows for adjustable fan speeds, ensuring that the cooling tower can respond effectively to fluctuating thermal loads.

The HP700 also boasts a unique, patented fill design that maximizes water distribution and contact time. This enhanced fill enhances heat transfer efficiency, allowing for more effective cooling in a compact footprint. The fill material is constructed from durable, corrosion-resistant materials, ensuring longevity and reduced maintenance needs.

Energy efficiency is a priority for the HP700, which incorporates the latest technologies in terms of heat exchange and water management. The design includes advanced drift eliminators that reduce water loss, while specially designed nozzles ensure optimal water distribution across the fill. This innovative approach not only preserves water resources but also enhances overall system performance.

In terms of construction, the HP700 is built with high-strength materials, including fiberglass-reinforced plastic and stainless steel. These materials offer superior resistance to corrosion and wear, making the HP700 suitable for a variety of environments, including those with harsh chemical exposure or varying weather conditions.

Another noteworthy characteristic of the HP700 is its modular design, which allows for easy installation and scalability. This feature enables facilities to expand their cooling capabilities as their requirements grow, ensuring long-term operational flexibility. Additionally, SPX Cooling Technologies provides comprehensive support services, including installation assistance and ongoing maintenance, further enhancing the value of the HP700.

In summary, the SPX Cooling Technologies HP700 is a highly efficient, durable, and flexible cooling solution that stands out in the competitive market. Its cutting-edge features, including advanced fan technology, optimized fill design, and energy-efficient operation, make it an excellent choice for a wide range of industrial and commercial cooling applications. With its commitment to quality and performance, SPX Cooling Technologies continues to lead the way in innovative cooling solutions.
