NCF-EC Series EC-Tech Forced Draft Closed Cooling Tower
NEWIN NCF-EC series is a groundbreaking modular open-type cooling tower. By integrating a centrifugal EC smart fan system, forced draft technology, and Armour anti-corrosion upgrades, it not only innovates upon the classic counter-flow open design but also significantly enhances equipment adaptability and operational reliability under complex working conditions.
ADVANTAGES
> Smart & Energy Efficient: The EC centrifugal fan features built-in automatic frequency conversion, offering high energy efficiency and low-noise operation.
> Highly Efficient Heat Dissipation: Combines forced draft with counter-flow design for stable heat exchange, particularly suitable for large temperature difference scenarios.
> Robust & Durable: Constructed with Armour anti-corrosion steel plate, providing strong corrosion resistance and extended equipment lifespan.
> Compact Structure: Modular design requires a small footprint, allows flexible layout, and features an aesthetically pleasing appearance.
> Strong Adaptability: Effectively handles challenging environments such as poor ventilation and inferior water quality, ensuring high reliability.
EC- GREEN TECH Applicated In Cooling Tower
Multiple EC Centrifugal Fans Design
> Multiple EC centrifugal fans can provide improved and uniform air extraction, ensuring air flow fully through the heat exchange coils, resulting in wider coverage and enhanced thermal efficiency.
> The forced draft fan drive is capable of providing long-distance air supply, making it particularly suitable for poorly ventilated areas.
Operational Redundancy Option
> When multiple fans are operating in parallel, if one fan malfunctions, the remaining fans can compensate for the loss of airflow by increasing their speed. Additionally, the replacement process for a malfunctioning fan can be carried out swiftly while the tower is still in operation.
> Redundancy advantage is one of the advantages of EC fan systems compared with AC fan systems.
Counter Flow Closed Type System
> The forced action of the fan facilitates the easy entry and passage of air flow through the stainless steel heat exchange coil, resulting in a counter-flow to the water flow, thereby maximizing contact and enhancing heat exchange efficiency.
> The closed type system, utilizing the stainless steel heat exchange coil for the circulation of the cooling medium and achieving cooling through wall-type heat exchange between spray water and the coil, ensures media purity, reduces maintenance costs, and conserves valuable water resources while providing efficient cooling.
About Other Main Parts
Perfectly matched components (controller/motor/PP impeller)
> The enhanced impeller technology and new EC motor lead to a substantial increase in efficiency, resulting in energy savings of 30%~40% compared to general centrifugal fans.
> The new motor in GreenTech EC technology with integrated control electronics;
> High power density; Robust design and maintenance-free operation; Easy initial set-up.
> EC Motor: Degree of protection: IP55, Insulation class : F, Super Premium Efficiency is up to IE5.
> The PVC heat exchange layer is composed of the cellular type fill blocks, which are highly resistant to pressure drop. The specially crafted fill sheets create a systematic and compact fluid channel once they are bonded together.
> As multiple layers of filler blocks are stacked, the water spray area expands, facilitating complete contact between water and air in order to enhance heat exchange efficiency.
> Efficiently extracting airborne water droplets, small wind resistance and an impressive capture rate of 99.99%, thus guaranteeing optimal heat transfer performance.
> The strategically positioned ABS Three-splashed-Nozzles, evenly water distribution under low pressure flow; Large caliber and three splashed type design, not easy to block, enhance spray coverage and guarantee continuous effective spraying, ensuring the efficient cooling performance of cooling tower.
