Product Description

NECH Series Evaporative Condenser/ Closed Cooling Tower
NECH is a prominent and widely used type of evaporative condenser, renowned for its exceptional mixed flow heat transfer mechanism. The design ingeniously combines the vertical cross-flow direction of both air and refrigerant steam. This strategic configuration ensures that air flows uniformly across the condenser, significantly boosting the heat exchange efficiency for optimal performance.

Advantages

 

· Our cutting-edge mixed flow heat transfer technology ensures significantly higher condensation efficiency, setting a new benchmark in cooling performance.
With a meticulously designed vertical cross flow direction for air and refrigerant steam, our system guarantees that airflow is evenly distributed throughout the condenser, optimizing efficient heat transfer like never before.

· Experience enhanced cooling efficiency through secondary heat transfer.

In our process, spray water traverses the condenser coil for an initial heat exchange, then descends through the lower PVC heat exchange layer for a secondary transfer, before finally collecting in the water basin for recycling. This innovative process maximizes cooling efficiency.

· Embrace sustainability with our Closed Circuit System, designed for Energy Saving and Environmental Protection.

Our system features a closed-loop gaseous state refrigerant, offering a clean operation that reduces water consumption and maintenance costs, while extending the service life of the equipment.

· Featuring a Compact Structure Design, our system boasts High Strength and Convenience.

The design requires minimal space, facilitating easy shipment and ensuring ease of installation and maintenance.

 

Work Principle

When the NECH evaporative condenser by Newin (Guangdong) Machinery Co., Ltd. is in operation, a harmonious symphony of advanced technology takes place:
The robust condensing coil serves as the primary conduit for refrigerant steam, which is expertly condensed into liquid through the innovative process of evaporative cooling and heat absorption, facilitated by a continuous spray of water. This spray water elegantly cascades through the coil unit, flowing seamlessly into the sophisticated PVC heat exchange system, thereby progressing to a secondary heat transfer stage. Concurrently, the high-performance axial flow fan delivers the necessary power, inducing the air to create a cross-flow within the condenser, efficiently exchanging heat with the refrigerant steam, thus achieving superior condensation performance.

Instructions for Selection
1. Begin by confirming the condensing temperature and wet bulb temperature, ensuring you have precise environmental parameters.
2. Proceed to calculate the total heat abstraction amount that flows through the system to reach the condensers, a crucial step for optimizing efficiency.
3. Reference either Table 2 or Table 3 to select the appropriate heat abstraction amount correction index, a key determinant in system performance.
4. Multiply the total heat abstraction amount by the heat correction index to determine the condensing load required under the specified working conditions.
5. Finally, consult the Graph Specification sheet to select the heat abstraction amount data that is larger or equivalent to the corrected data, ensuring the system operates within optimal parameters.
