Product Description

Introducing the NECH Series Evaporative Condenser / Closed Cooling Tower: a cutting-edge solution tailored for optimal cooling performance.
NECH The NECH is a distinguished model in the realm of evaporative condensers, celebrated for its innovative mixed flow heat transfer mechanism. By seamlessly integrating the vertical cross-flow direction of both air and refrigerant steam, this advanced design ensures a uniform air distribution throughout the condenser, significantly elevating the overall heat exchange efficiency.

Advantages

 

· Revolutionary mixed flow heat transfer ensures superior condensation efficiency, setting new standards in performance.
Ingeniously designed with a vertical cross flow of air and refrigerant steam, our system guarantees uniform airflow through the condenser, optimizing heat transfer for unparalleled efficiency.

· Enhanced through secondary heat transfer, our system takes cooling efficiency to the next level.

Our expertly engineered spray water system flows seamlessly through the condenser coil for initial heat exchange, then cascades through the lower PVC heat exchange layer for secondary heat transfer. Finally, the water gathers in the collection basin ready for recycling, optimizing cooling efficiency every step of the way.

· Innovative closed circuit system for ultimate energy savings and environmental conservation.

By keeping the refrigerant in a gaseous state within a closed coil circulation, our system remains pristine, significantly cutting down on water usage and maintenance costs, while extending the equipment's lifespan.

· Sleek compact structure design, built for high strength and unmatched convenience.

With a minimal footprint, our system is designed for easy shipment, swift installation, and hassle-free maintenance, making it the perfect choice for modern needs.

 

Work Principle

When the NECH evaporative condenser is in operation, a fascinating process unfolds:
The condensing coil serves as the primary channel for refrigerant steam, which transforms the refrigerant steam into liquid form by evaporating and efficiently absorbing heat through a fine mist of spraying water. This spray water flows seamlessly through the coil unit and then cascades into a PVC heat exchange system, continuing its secondary heat transfer process. Simultaneously, the powerful axial flow fan generates a forceful current, creating a dynamic cross flow of air within the condenser that interacts and exchanges heat with the refrigerant steam, ultimately achieving superior and efficient condensation performance.
