Product Description

NECH Series Evaporative Condenser/ Closed Cooling Tower
NECH is a widely recognized type of evaporative condenser, celebrated for its innovative mixed flow heat transfer design. With the clever vertical cross-flow direction of air and refrigerant steam, this advanced configuration ensures that air circulates effortlessly and uniformly throughout the condenser. This results in an outstandingly high heat exchange efficiency, setting a new standard in cooling technology.

Advantages

 

· Innovative mixed flow heat transfer technology ensures an elevated condensation efficiency. Experience optimal performance with every use.
With a unique vertical cross-flow direction for both air and refrigerant steam, the design ensures a balanced and even air passage through the condenser, guaranteeing efficient and effective heat transfer.

· Enhanced secondary heat transfer mechanism significantly boosts cooling efficiency, setting a new standard in the industry.

The spray water is ingeniously directed through the condenser coil initially for a primary heat exchange, then cascades through the lower section equipped with a PVC heat exchange layer for secondary transfer, and finally collects in a basin for recycling. This comprehensive process dramatically elevates cooling efficiency.

· Environmentally-friendly closed circuit system for unparalleled energy savings.

The refrigerant in a gaseous state condenses within the sealed coil, maintaining cleanliness, reducing water usage, and slashing maintenance costs. This leads to a prolonged equipment lifespan, embodying energy efficiency and environmental stewardship.

· Robust compact structure design offers exceptional strength and convenience.

Occupying minimal space, our design facilitates easy shipment, seamless installation, and hassle-free maintenance, providing unparalleled convenience and efficiency.

 

Work Principle

When the NECH evaporative condenser is at work:
The condensing coil serves as the primary conduit for refrigerant steam, where it transforms the refrigerant steam into a liquid state through a sophisticated process of heat absorption and evaporation, achieved by a meticulously engineered water spray. This spray flows graciously over the coil unit, subsequently entering the advanced PVC heat exchange system, continuing along a secondary phase of heat transfer. Simultaneously, the robust axial flow fan generates the necessary power, orchestrating a dynamic cross-flow of air within the condenser to facilitate an optimal heat exchange with the refrigerant steam, thereby ensuring superior condensation performance.

Instructions for Selection
1. Begin by confirming both the condensing temperature and the wet bulb temperature. These are crucial starting points for optimal selection.
2. Proceed to calculate the total heat abstraction amount that flows through your system into the condensers. Precision here is key to efficiency.
3. Reference the data in Table 2 or Table 3, and select the most appropriate heat abstraction amount correction index to suit your needs.
4. Multiply the total heat abstraction amount by the heat correction index. This will yield the exact condensing load required under your specific working conditions.
5. Consult the Graph Specification sheet. Choose the heat abstraction amount data that is either greater than or equal to the corrected data for assurance of peak performance.
