Product Description

Introducing the NECH Series Evaporative Condenser/Closed Cooling Tower, a marvel of advanced engineering that redefines efficiency and reliability in thermal management. Designed with precision, this series promises unmatched performance and durability.
NECH: The Pinnacle of Cutting-edge Condenser Technology The NECH Series represents one of the most sought-after types of evaporative condensers, renowned for its innovative mixed flow heat transfer system. This strategic design capitalizes on the vertical cross-flow direction between air and refrigerant steam, ensuring that air circulates uniformly through the condenser. The result is a significant boost in heat exchange efficiency, making it an ideal choice for optimizing cooling performance in various industrial applications.

Advantages

 

· Innovative mixed flow heat transfer for unparalleled condensation efficiency, ensuring top-tier performance.
With its advanced vertical cross flow, air and refrigerant steam are perfectly aligned, ensuring an even airflow through the condenser for optimal and efficient heat transfer.

· Leverage our secondary heat transfer system for superior cooling performance and efficiency.

Experience enhanced cooling efficiency with our system: Spray water passes through the condenser coil for initial heat exchange, then continues to the lower PVC heat exchange layer for secondary transfer, culminating in recycling at the water collection basin.

· Closed circuit system: The epitome of energy efficiency and environmental responsibility.

Gaseous refrigerants condense within a closed loop, maintaining cleanliness, drastically cutting water consumption and reducing maintenance costs, thereby extending the equipment's service life.

· Ingenious compact structure design ensures robust strength and exceptional convenience.

Its small footprint facilitates easy shipment, installation, and maintenance, making it an ideal solution for space-conscious applications.

 

Work Principle

When the NECH evaporative condenser swings into action, marvel at its seamless operation:
The condensing coil serves as the primary artery for the refrigerant steam, ingeniously transforming this steam into liquid. This transformation occurs through the masterful process of evaporation and heat absorption, facilitated by the precise spraying of water. The spray water elegantly flows over the coil unit, cascading into the PVC heat exchangesystem, where it continues its secondary heat transfer. Concurrently, the powerful axial flow fan injects energy into the process, creating a dynamic cross flow of air within the condenser. This airflow engages in a critical heat exchange with the refrigerant steam,culminating in an extraordinary level of condensation performance that is both efficient and reliable.

Instructions for Selection
1. Begin by confirming the condensing temperature alongside the wet bulb temperature, essential for optimal selection.
2. Proceed to calculate the total heat abstraction amount, which is essential for the system as it passes through to the condensers.
3. Use Table 2 or Table 3 as your trusted reference to select the correct heat abstraction amount correction index, ensuring precision.
4. Multiply the total amount of heat abstraction by the heat correction index to determine the condensing load under the specified working conditions.
5. Refer to the Graph Specification sheet to choose the heat abstraction amount data that is greater than or equal to the corrected data value, ensuring the best fit.
