Product Description

Discover the NECH Series Evaporative Condenser/Closed Cooling Tower, where cutting-edge technology meets unmatched efficiency.
NECH is an innovative and widely used type of evaporative condenser. Distinguished by its unique mixed flow heat transfer, it features a vertical cross flow direction of air and refrigerant steam. This advanced design ensures a uniform air flow throughout the condenser, significantly boosting heat exchange efficiency, setting a new standard in performance.

Advantages

 

· Innovative mixed flow heat transfer technology elevates condensation efficiency to new heights.
The ingenious vertical cross flow of air and refrigerant steam ensures uniform air distribution throughout the condenser, enabling extraordinarily efficient heat transfer.

· Revolutionary secondary heat transfer for enhanced cooling performance.

Spray water gracefully cascades through the condenser coil, initiating the first heat exchange. It then journeys through the lower section, comprised of a PVC heat exchange layer, for a secondary heat transfer before descending into the water collection basin for recycling. This sophisticated process substantially boosts cooling efficacy.

· Closed Circuit System: A Pinnacle of Energy Efficiency and Environmental Stewardship

The refrigerant, in its gaseous state, undergoes condensation and circulates within the coil in a pristine closed circuit. This mechanism ensures cleanliness, significantly reduces water usage and maintenance costs, and extends the equipment's lifespan.

· Ingeniously Compact Design: Strength Meets Convenience

With a minimal footprint, this design ensures effortless shipping, seamless installation, and straightforward maintenance.

 

Work Principle

When NECH evaporative condenser is in operation:
The condensing coil serves as the primary conduit for refrigerant steam, a critical component which transforms the refrigerant steam into liquid. This transformation is achieved through a sophisticated process of evaporating and absorbing heat, enhanced by the strategic spraying of water. As the spray water cascades over the coil unit, it proceeds into the advanced PVC heat exchange system, facilitating a secondary, highly efficient heat transfer mechanism. Concurrently, the powerful axial flow fan generates dynamic airflow, creating a cross flow within the condenser. This induces an intensive heat exchange with the refrigerant steam,successfully achieving superior and efficient condensation performance.
