Product Description

Introducing the NECN Series: Revolutionary Evaporative Condenser and Closed Cooling Tower

NECN  is a special evaporative condenser, which is characterized by its counter flow heat transfer ( the opposite flow direction of air and refrigerant steam). This design allows for fuller heat exchange between air and refrigerant steam inside the condenser, thereby improving condensation efficiency.

Advantages

· Counter flow heat transfer, Higher condensation efficiency
Efficient condensation performance specially in hot and humid conditions.

· Closed circuit system, Energy saving and Environmental protection
Keep media clean, reduce water consumption and maintenance cost, longer equipment service life.

· Compact structure design, High Strength and Convenient
Small occupation area, Convenient to the shipment, Ease of installation and maintenance.

 

Work Principle

When NECN evaporative condenser is in operation: 
The condensing coil is the main channel of refrigerant steam, which condenses the refrigerant steam into liquid by the way of evaporating and absorbing heat by spraying water. At the same time, the axial flow fan provides forced convection, which causes the air to form a counter flow inside the condenser and exchange heat with the refrigerant steam, so that to achieve efficient condensation performance.
