High-Capacity Dry Air Cooler for Innovative Cooling Solutions
NWFL-V The NWFL-V series represents a remarkable leap forward in the realm of high-performance cooling technology, featuring a V-type dry air cooler ingeniously engineered with a state-of-the-art Free Cooling System. This system ensures extraordinary cooling efficiency, making it exceptionally well-suited for HVAC systems and a myriad of other facilities. A standout feature is its non-water consumption, offering a sustainable and cost-effective alternative to traditional evaporative cooling methods.
Features
· Ingenious V-type design coupled with an outstanding Free cooling system,
Ensuring unparalleled cooling efficiency while remarkably conserving water resources with zero consumption.
· Incorporation of optimally efficient components, such as the advanced EC motor,
Guaranteeing maximum system efficiency and significant energy savings.
· Substantial redundancy incorporated,
Effectively eliminating any potential thermal performance losses.
· Exceptional reliability paired with straightforward and hassle-free maintenance.
Working Principle
When the remarkable NWFL-V adiabatic cooler is set into action:
The advanced EC fan system initiates the process by drawing in the refreshingly cool and dry air. This air is then guided into the tower through our meticulously designed V-shaped finned tube heat exchanger. The innovative and large-contact-surface V-shaped construction greatly enhances the cooling dynamics, swiftly accelerating the cooling of both the air and the hot process fluid. This design brilliantly boosts heat exchange efficiency. Once the air has engaged in thorough partition wall heat exchange with the cool, dry air, the now hot and saturated air is efficiently expelled from the tower. The result is the achievement of unparalleled Free Cooling, utilizing non-evaporative cooling methods, to create an exceptionally efficient cooling solution.
