From Hot Condenser Water to Cooled Return

01
Hot Water Enters Condenser water from the chiller enters the top of the cooling tower.
02
Water Distribution The water is evenly distributed over the fill media.
03
Airflow The axial fan draws air through the tower.
04
Heat Transfer A small portion of the water evaporates, removing heat from the remaining water.
05
Cooled Water Returns The cooled water collects in the basin and returns to the chiller condenser.

This evaporative cooling process allows the water temperature to approach the ambient wet-bulb temperature, significantly improving system efficiency.

How to Select the Right Cooling Tower

01

Determine Water Flow

Select the tower based on the required condenser water flow rate (m³/h).

02

Confirm Temperature Range

Standard design conditions:

  • Inlet: 37°C
  • Outlet: 32°C
  • Range: 5°C
03

Check Available Space

Verify installation area, height restrictions, and service access requirements.

04

Consider Future Expansion

For growing facilities, select a model with additional capacity margin or allow space for parallel towers.

Common Questions

What is the difference between open and closed circuit cooling towers?

The KT Series is an open circuit cooling tower, where condenser water is directly exposed to the airflow for maximum heat rejection efficiency.

How do I choose the correct cooling tower size?

The most important parameter is the required water flow rate (m³/h), followed by the entering and leaving water temperatures and the local wet-bulb temperature.

Can the cooling tower be installed outdoors?

Yes. The FRP structure is designed for outdoor installation and long-term exposure to weather and industrial environments.

What maintenance is required?

Routine maintenance includes checking water quality, cleaning the fill media, inspecting the fan and motor, and verifying water distribution performance.

Can multiple towers operate in parallel?

Yes. Multiple KT Series towers can be installed in parallel for larger cooling capacities or future system expansion.
