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.

KCH Series Forced-flow Closed Cooling Tower
The KCH Series Parallel Flow Closed Circuit Cooling Tower is designed to remove process heat through evaporative cooling, combining spray water, airflow, and heat exchange coils to deliver highly efficient thermal performance.
Unlike conventional counterflow designs, the KCH Series features a parallel flow configuration in which ambient air and spray water move in the same direction across the coil surface. This operating principle maximizes coil wetting, significantly reducing scaling on the coil surface and making the unit especially suitable for high-temperature process fluids and applications with large cooling temperature differentials.
Product Description
Operating Principle
The process fluid — water, oil, or other process liquids — circulates inside the heat exchange coil, while the external coil surface is continuously wetted by recirculated spray water.
Heat is transferred through the coil wall to the spray water and surrounding air. Under fan-induced airflow, heat is discharged to the atmosphere through combined sensible and evaporative heat transfer.
As spray water recirculates, it passes through high-efficiency PVC fill media, where water temperature is reduced before re-entering the spray system. Since airflow and spray water move in the same direction, the coil surface remains uniformly wetted, minimizing dry spots and significantly reducing scaling formation.
This operating principle makes the KCH Series particularly suitable for cooling high-temperature process fluids around 60°C, or applications with relatively large cooling ranges such as 60°C to 35°C.
