Product Description

NECH Series Evaporative Condenser/ Closed Cooling Tower - Where Innovation Meets Efficiency
NECH - Cutting-edge Performance, Timeless Reliability is a renowned type of evaporative condenser, celebrated for its innovative mixed flow heat transfer design. This unique feature, characterized by the vertical cross flow direction of air and refrigerant steam, ensures that air flows seamlessly and uniformly through the condenser, resulting in superior heat exchange efficiency. Experience the pinnacle of cooling technology with every application.

Advantages

 

· Innovative Mixed Flow Heat Transfer: Elevating condensation efficiency to new heights.
Experience superior performance with our vertical cross-flow system, ensuring air and refrigerant steam journey seamlessly for optimal condenser efficiency and robust heat transfer.

· Dual-Stage Heat Exchange: Unlocking unparalleled cooling prowess.

Our spray water meticulously traverses the condenser coil, initiating a primary exchange, then elegantly moves through the lower PVC heat exchange layer for a secondary transfer, culminating in a recycling process in the water collection basin, thereby amplifying cooling efficiency.

· Environmentally Conscious Closed Circuit System: A promise of sustainability and energy conservation.

The refrigerant, in its gaseous state, undergoes a seamless closed-loop condensation within the coil, promoting cleanliness and drastically reducing water usage and maintenance costs, while extending the longevity of the equipment.

· Ingenious Compact Design: Where Strength Meets Convenience

Occupying minimal space, our design ensures effortless shipping, installation, and maintenance, offering high strength and unparalleled ease of use.

 

Work Principle

When the NECH evaporative condenser is set in motion:
The condensing coil serves as the primary pathway for refrigerant steam, a vital component that meticulously transforms refrigerant steam into a liquid state. This transformation is achieved through the evaporative cooling process, where heat is absorbed efficiently by spray water. The spray water cascades through the coil unit and is directed into a sophisticated PVC heat exchange system,continuing the journey with secondary heat transfer. Simultaneously, an axial flow fan delivers powerful momentum, creating a dynamic cross-flow of air within the condenser. This movement facilitates a robust heat exchange with the refrigerant steam,culminating in outstanding condensation performance.
