NST series Cross Flow Open Type Cooling Tower  
The NST series cooling tower features a cross-flow open design and is widely utilized in small and medium-sized industries, HVAC systems, and locations with lower water quality requirements. Additionally, a multi-cells design could be provided based on specific working conditions.

FEATURES
CTI Certified, Performance Ensurance
 

• The cross flow open-loop system design allows for a large filler heat exchange area, ensuring ample contact with air and enabling fast heat transfer, ultimately resulting in high efficiency.

• Maximize the utilization of water resources and minimize wastage, while implementing the principle of natural ventilation to decrease energy consumption.

• The internal structure of the fill packing layer and tower body is robust and stable, exhibiting exceptional impact resistance, ensuring that the packing remains undamaged and unobstructed.

• Simple construction and internal maintenance platform designed for making operation and maintenance convenient.

MAIN PARTS

300x200

> Axial Fan Drive System

The design of the forward blade structure and streamlined high-strength axial flow fan, along with the belt reduction drive, ensures smooth transmission, high efficiency, low noise, and simple maintenance. The motor boasts a protection grade of IP55 and an insulation grade of F, providing enhanced safety and reliability.* Gearbox reducer ，Two-speed or variable frequency, anti-explosion motor or permanent magnet motor is optional. The system can also be enhanced to utilize a permanent magnet motor direct drive fan, resulting in additional power savings.

300x200

> PVC Filler Integrated Drift Eliminator & Air Inlet Grille

Significantly minimize water drift loss, and ensure optimal heat transfer performance. The unique surface texture provides ample heat exchange surface area, enhancing overall efficiency. *High-temp resistant filler is optional to meet the requirement of special working conditions.






 

300x200

> Water Distribution

The hot water basin is equipped with densely spaced anti-clogging PP nozzles, ensuring the uniform distribution of gravity-fed water for an optimal spray coverage.* Optional High- Low Varied Flow Nozzles guarantee uniform water distribution even in low flow conditions.








 

300x200

> Internal Maintenance Platform

The dual-tiered maintenance platform is utilized for the internal upkeep of the cooling tower, particularly for the maintenance of the fan system, providing a safe and convenient solution.










 

 

Optional Various Additional Functions

Two-speed& VFD variable frequency motor/ Permanent magnet motor direct fan drive system/ Vibration Cut-off Switch/ Electronic descaler/ Water treatment equipment/ Anti-freeze automatic heating system/ Noise reduction upgrade/ External maintenance platform and guardrail/Installation and maintenance boom etc.
 

Other Upgraded Type NST series FRP Cooling Tower Solutions To Meet Different Working Conditions
 

300x200

ANTI-FREEZING
- Equipped With Air Inlet Grille

> During the colder seasons, optional air inlet grilles are installed on both sides to prevent the PVC heat exchange filler from freezing.



 

300x200

NOISE REDUCTION& ANTI-CORROSION UPGRADED

> A tailor-made noise reduction system is employed above the fan stack, effectively absorbing and diminishing the sound emanating from the air outlet.
> The cooling tower frame is constructed with a all-stainless steel structure, enhancing its stability and further elevating its anti-corrosion properties，prolong equipment lifespan.

300x200

FULL FRP COOLING TOWER SOLUTION
- For plants with poor water quality 

> Full FRP structure, excellent corrosion resistant, design lifespan is up to 30 years.
> Non-clogging "L" type splash fills are utilized for heat exchange, high efficiency and low maintenance cost.
