Product Description

NECH Series Evaporative Condenser/ Closed Cooling Tower

NECH This remarkable NECH model stands as one of the quintessential types of evaporative condensers, uniquely distinctive for its innovative mixed flow heat transfer system. With its vertical cross-flow direction of air and refrigerant steam, this exceptional design ensures that air flows uniformly across the condenser, effectively maximizing the heat exchange efficiency for unparalleled performance.

Advantages

 

· Experience unmatched efficiency with our mixed flow heat transfer design, ensuring an elevated level of condensation efficiency that sets new standards.
Our innovative vertical cross-flow design allows air and refrigerant steam to seamlessly interact, guaranteeing the air flows uniformly through the condenser for optimized and efficient heat transfer.

· Leverage secondary heat transfer to achieve superior cooling efficiency, pushing the boundaries of what is possible in temperature control.

Ingeniously designed, the spray water circulates through the condenser coil, initiating the first heat exchange. It then travels through the lower PVC heat exchange layer for a secondary heat transfer before falling into the water collection basin for recycling. This meticulous process significantly enhances cooling efficiency.

· Our closed circuit system is the epitome of energy efficiency and environmental consciousness, making it an ideal choice for the modern age.

The refrigerant remains in a gaseous state, condensing and circulating within the coil in a closed system. This not only keeps the system clean but also minimizes water consumption and maintenance costs, ensuring a longer service life for the equipment.

· Compact yet powerful, our design offers high strength with unparalleled convenience.

The compact structure minimizes space requirements, facilitating easy shipment, and ensuring straightforward installation and maintenance, making it an effortless addition to any setup.

 

Work Principle

When the NECH evaporative condenser is operational:
The condensing coil serves as the primary pathway for refrigerant steam, which transforms the refrigerant steam into liquid by evaporating and effectively absorbing heat through a sophisticated water spray mechanism. This spray water travels through the coil unit, subsequently flowing into the advanced PVC heat exchange system, continuing the secondary heat transfer process. Simultaneously, the powerful axial flow fan generates a strong force, creating an effective cross flow of air inside the condenser, allowing for comprehensive heat exchange with the refrigerant steam, ultimately achieving exceptional condensation performance.
