Product Description

NECH Series: Evaporative Condenser / Closed Cooling Tower
NECH The NECH model stands as one of the quintessential types of evaporative condensers, renowned for its innovative mixed flow heat transfer system. This advanced design ensures a harmonious vertical cross flow of air and refrigerant steam, facilitating an even distribution of airflow throughout the condenser. The result? Enhanced heat exchange efficiency that sets a benchmark in cooling performance.

Advantages

 

· Experience the power of mixed flow heat transfer, where superior condensation efficiency is achieved effortlessly.
The ingenious vertical cross flow direction ensures that air and refrigerant steam blend harmoniously, guaranteeing that the airflow evenly permeates the condenser for optimal heat transfer efficiency.

· Harness the power of secondary heat transfer to significantly enhance cooling efficiency.

Our innovative design allows spray water to cascade through the condenser coil, engaging in a primary heat exchange, before continuing on through the lower PVC heat exchange layer for a secondary interaction. This well-orchestrated flow culminates in the water collection basin, ready for recycling. This meticulous process dramatically improves cooling efficiency.

· Revolutionary closed circuit system that champions energy savings and environmental protection.

Our system's gaseous refrigerant condenses within a closed coil circuit, preserving cleanliness while significantly reducing water consumption and maintenance expenses. This not only extends the equipment's service life but also ensures an eco-friendly operation.

· Impressive compact structure design, embodying high strength and unmatched convenience.

Its minimal footprint makes it ideal for shipping, installation, and maintenance, offering an effortless experience from start to finish.

 

Work Principle

When the NECH evaporative condenser is in operation, a sophisticated process unfolds:
The condensing coil acts as the primary conduit for refrigerant steam, serving as the essential channel through which the refrigerant steam is transformed into liquid. This transformation occurs by harnessing the power of evaporation and heat absorption, masterfully utilizing the spray of waterto facilitate this process. Spray water flows gracefully through the coil unit, making its way into the innovatively designed PVC heat exchange,where it continues its journey through an additional stage of secondary heat transfer,ensuring optimal cooling. Simultaneously, the highly efficient axial flow fan generates power, creating a dynamic cross flow of air within the condenser. This airflow interacts seamlessly with the refrigerant steam,culminating in unparalleled condensation performance and efficiency.
