The KFCN Series Hybrid Closed Circuit Cooling Tower combines the benefits of dry cooling and evaporative cooling in a single high-efficiency system. Through a finned pre-cooling heat exchanger located above the evaporative section, process fluid is partially cooled before entering the wet cooling stage.

KCN Series Counter-flow Closed Cooling Tower
The KCN Series Counterflow Closed Circuit Cooling Tower removes process heat through evaporative cooling. Heat from the process fluid circulating inside the coil is transferred to the external spray water, while an induced-draft fan discharges heat to the atmosphere through evaporation.
Designed with a bottom air intake configuration, ambient air flows upward in the opposite direction of the falling spray water, creating a counterflow heat exchange pattern. This configuration enables efficient thermal performance and a compact equipment footprint, making it particularly suitable for low approach temperature applications and installations with limited space.
Product Description
Operating Principle
The process fluid circulates inside the heat exchange coil, where heat is transferred through the coil wall to the continuously recirculated spray water on the external surface.
Under the action of the axial fan, ambient air enters from the air inlet and travels upward in the opposite direction of the spray water flow. A portion of the spray water evaporates, removing heat through the latent heat of evaporation. The heated, moisture-laden air is discharged through the top of the unit.
The remaining spray water falls into the cold water basin and is recirculated through the spray system for continuous operation.
