CLOSED LOOP COOLING TOWER

Energy-Efficient

Closed Circuit Cooling Tower

Our core competency is One stop service for cooling tower while improving the efficiency of existing cooling tower with energy saving

KCN Series

Counter flow Closed Circuit Cooling Tower

More Compact Structure

The counterflow tower has compact design that maximizes coil surface area within a smaller footprint, making it ideal for low-temperature cooling with small temperature differentials.

• Compact structure, space-saving design
• High heat exchange efficiency per unit area
• Easy to install, operate, and maintain

Optional Auxiliary System Integration

Casen offers compact integrated systems for small-scale cooling,

combining a counterflow closed circuit tower, pump, tank, and controls into a convenient plug-and-play unit..

High-Efficiency Coil Heat Exchanger

(Multiple Types/Materials Available)

The large-capacity coil design improves energy efficiency and cooling performance by enabling greater heat

Spacious Maintenance Access

The unit features extra-large maintenance space, along with access doors and wide internal passages, allowing maintenance personnel to easily carry out inspection and servicing inside the unitmaking maintenance safer and more convenient.

KCN Series

ParallelFlowClosed Circuit Cooling Tower

Parallel Air-Water Flow for Superior

Heat Exchange Performance

The KCH Series features a co-current air-water flow design,

combining coil heat exchange with PVC fill for efficient secondary heat transfer. This configuration reduces scale formation by ensuring the coil surface stays fully wetted, minimizing scale

buildup compared to counterflow towers.

Fill Design Minimizes Coil Usage And Reduces Cost

The fill design enhances spray water heat exchange, reducing

 airflow needs and saving energy. As the water passes through PVC fill, it cools while flowing with the air, improving the cooling

 effect and reducing coil surface area, thus lowering

manufacturing costs.

KCN Series

CrossflowClosed Circuit Cooling Tower

Parallel Air-Water Flow for Superior Heat Exchange Performance

The KCF Series features a co-current air-water mixed flow design, combining coil heat exchangers with PVC fill material for efficient secondary heat transfer. This design also reduces scale formation on the coil surface. Air and spray water flow over the coils simultaneously, ensuring full coverage and a wetted coil surface, which minimizes scaling compared to counterflow towers.

Fill Design Minimizes Coil Usage And Reduces Cost

The fill structure improves spray heat exchange efficiency, reducing airflow needs and saving energy. Spray water is cooled by PVC fill and flows horizontally with incoming air, relying on lower water temperatures for better cooling. This minimizes coil surface area, cutting manufacturing costs.

KWN/H Series

Sewage Cooling Tower

Simple structure easy to disassemble

The system features high structural strength and good pressure-bearing capacity, with an allowable working pressure of 1.6MPa. It allows for independent cleaning of each heat exchange tube. The inclined angle of the heat exchange tubes prevents dirt or debris buildup and enables automatic emptying.

Mechanically Cleanable Header Box Design

The sewage cooling tower featuresa mechanically cleanable header structure at the end of the heat exchange tubes, allowing easy access with minimal or no disassembly. This design enables efficient flushing of residues during maintenance, ensures the reuse of heat exchange tubes, and prevents issues like poor heat exchange performance, tube blockages, and complicated cleaning procedures caused by special media.

• Easy maintenance and inspection Timely flushing of
• residues to prevent blockage Reusable heat
• exchange tubes for repeated cycles Effectively
• improves poor heat exchange performance

Inline Heat Exchange Tubes

(Multiple Types/Materials Available)

The sewage cooling tower uses inline heat exchange tubes arranged at a steep angle for natural flow and easy drainage, ensuring good cleanability. Materials like 304, 316L, 2205 duplex stainless steel, and Ti-grade tubes are available based on corrosion resistance needs. The tube inner surface has a rough- ness of Ra 3.2μm, ensuring smooth flow and preventing blockages from excessive flow resistance.
