High-Capacity Dry Air Cooler for Innovative Cooling Solutions
NWFL-V series is the V type dry air cooler designed with Free Cooling System. Efficient cooling,especially suitable for HVAC sytem and other facilities, and non- water consumption is compared with evaporative cooling.
Features
· V type design and Free cooling system,
High cooling efficiency with non-water consumption.
· Optimal efficient components, like EC motor,
Maximum system efficiency and energy saving.
· Large redundancy available,
Eliminating thermal performance loss.
· High reliability and Ease maintenance.
Working Principle
When NWFL-V adiabatic cooler is in operation:
The EC fan system draws in the cool dry air, which then enters the tower through the V-shaped finned tube heat exchanger. The large contact surface of the V-shaped design accelerates the cooling process for both the air and hot process fluid, leading to a significant improvement in heat exchange efficiency. After undergoing sufficient partition wall heat exchange with the cool dry air, the hot saturated air is discharged outside of the tower, achieving efficient Free Cooling (non-evaporative cooling).
