Mixed Flow Evaporative Fluid Coolers / Closed Cooling Tower
NWF The NWF series closed cooling tower masterfully integrates state-of-the-art composite flow cooling technology to ensure stable operations, remarkable energy efficiency, and environmental harmony. After the spray water completes its task of cooling the heat exchange coil, it gracefully descends into the cold water basin via the efficient PVC heat exchange layer. This sophisticated process significantly lowers the internal tower temperature while cleverly minimizing any noise that might result from the direct descent of spray water into the bottom basin.
High-Efficiency Mixed Flow Closed Circuit System
Operation
Within this advanced system, the cooling medium navigates through the meticulously designed serpentine coil heat exchanger. An uninterrupted external spray system envelops the coil surface with a refreshing mist, facilitating optimal cooling. The cooled medium engages in a seamless exchange of heat with the spray water, orchestrated by a partition wall heat exchanger, culminating in a closed-loop of unparalleled cooling prowess. Invigoratingly cool, dry air enters laterally, converging vertically with the spray water’s trajectory, powered by fans to create an intricate composite heat transfer. Post heat exchange, the high-temperature saturated air exits the tower, while the spray water conducts a sophisticated secondary heat transfer through the PVC layer before being gracefully collected in the basin, ensuring an elite level of cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the medium remains uncontaminated, slashing maintenance costs while preserving invaluable water resources through its superbly efficient cooling process.
> The seamless synergy of a stainless steel coil heat exchanger and a PVC heat exchange layer delivers not only exceptional efficiency but also an element of sophistication. This trailblazing design maximizes the thermal transfer surface, boosts heat exchange performance, and subtly reduces noise levels.
> The innovative single-side air intake design ensures reduced noise emissions, making it perfectly suited for noise-sensitive environments.
> This product boasts a compact and space-efficient structure, facilitating the seamless integration of multiple cooling towers.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
The aluminum alloy axial flow fan showcases remarkable low noise operation, stability, and efficiency. The motor, fortified with an IP55 protection grade and an F insulation grade, guarantees exceptional safety and reliability.
2. External Spray System
This system expertly sprays cool water onto the heat exchange coil, consistently wetting the coil's surface to achieve optimal cooling results.
3. Stainless Steel Heat Exchange Coil
Stainless steel coils offer unmatched heat exchange efficiency, outstanding corrosion resistance, and lightweight design. Their recyclability underscores environmental sustainability, while also extending equipment lifespan.
4. MAH PVC Fill Film (PVC heat exchange layer)
The PVC filler heat exchange layer boasts an integrated design incorporating filler, air inlet grille, and drift eliminator. This ensures consistent air intake, drastically reduces water drift loss, and guarantees superior heat transfer performance. Additionally, the unique texture amplifies heat exchange surface area, enhancing overall efficiency. The filler can be upgraded to high-temperature materials, perfectly tailored to the project's specific working conditions.
5. MBD PVC Drift Eliminator
Specially crafted for closed cooling towers, this exclusive drift eliminator efficiently captures airborne water droplets, featuring minimal wind resistance and an incredibly high capture rate of 99.99%, thereby ensuring superior heat transfer performance.
6. Air Inlet Louver
Designed to evenly draw in cool, dry air, this louver facilitates the airflow through the coil and PVC heat exchange layer, simultaneously limiting exposure to sunlight and preventing microbial growth.
7. Heavy-duty construction
Constructed with a high-quality Z700 galvanized steel frame and shell,this structure offers exceptional corrosion resistance. For the most challenging environments, optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides unparalleled protection.
8. Access Door
Provides entry to the tower's inner maintenance platform through the access door.
The presence of an inspection platform within the cooling tower significantly enhances the ease and convenience of conducting inspections and maintenance activities.
