Square Closed-Circuit Cooling Tower

Closed-Loop · Cleaner Process Fluid · Reduced Contamination

Noran Square Closed-Circuit Cooling Towers are designed for reliable heat rejection in industrial cooling systems. The closed-loop design keeps the process fluid isolated from the external environment, helping maintain fluid cleanliness and reduce scaling and contamination.

Available in closed-circuit, crossflow/counterflow, and combined-flow configurations, the system can be customized to match different cooling capacities, water flow rates, and installation requirements.

1. Key Features

  1. Stainless Steel Construction– Excellent corrosion resistance and durability for long-term industrial operation.
  2. Closed-Loop Cooling– Keeps process fluid inside the heat-exchange coil, reducing contamination and scaling.
  3. Large Water Capacity– Square tower design supports high circulating water volumes and larger cooling systems.
  4. Flexible Configurations– Closed-circuit, crossflow/counterflow and combined-flow options are available.
  5. Customized Design– Cooling capacity, water flow, dimensions, fan configuration and heat-exchange components can be customized.
  6. Reliable & Low Maintenance– Robust construction helps provide stable performance and extended service life.


2. Working Principle

The closed-circuit cooling tower removes heat from the process fluid through a heat-exchange coil. The process fluid circulates inside the closed coil, while external spray water and airflow remove heat from the coil surface.

This closed-loop design helps reduce contamination and scaling while providing stable and efficient heat rejection for industrial cooling systems.

Process Fluid → Heat-Exchange Coil → Heat Transfer → Cooling Water & Air → Heat Dissipation

Ideal for Large-Scale & Centralized Cooling Systems

Square Closed-Circuit Cooling Towers are particularly suitable for large industrial plants and centralized process cooling systems where high cooling capacity, large circulating water flow and stable long-term operation are required.

They are a good choice for customers who:

  • Operate Large Manufacturing Plants
    Require centralized cooling for multiple production lines, machines or process equipment.
  • Need High Cooling Capacity & Large Water Flow
    Suitable for systems with high heat loads and large volumes of circulating cooling water.
  • Use Centralized Process Cooling Systems
    One cooling tower can serve multiple cooling points across a factory through a centralized cooling water loop.
  • Require Cleaner & More Stable Process Fluid
    The closed-loop design helps reduce contamination, scaling and exposure of process fluid to the external environment.
  • Have Limited Water Quality or Harsh Operating Conditions
    Closed-circuit cooling helps protect the process fluid and reduce the impact of external water quality on the cooling system.
  • Plan to Expand Production Capacity
    Customized tower capacity and configuration can be designed to accommodate current and future cooling requirements.


Typical Applications

Large Manufacturing Plants · Chemical Processing · Pharmaceutical Manufacturing · Food & Beverage · Plastics & Rubber · Metal Processing · Electronics & Photovoltaic · Centralized Industrial Cooling Systems
