1. Equipment Name

Shell and Tube Closed Circuit Cooling Water Heat Exchanger
(CCCW Heat Exchanger)

2. Product Overview

This equipment is a shell and tube type heat exchanger designed specifically for Closed Circuit Cooling Water (CCCW) systems. It is primarily used to cool critical components in industrial systems by transferring heat from the closed-loop cooling water to an external medium such as raw water, seawater, or cooling tower water.

The CCCW heat exchanger maintains a fully enclosed circuit on the cooling water side, preventing contamination, corrosion, and scaling, while ensuring high operational reliability. It is widely used in power plants, petrochemical industries, metallurgy, data centers, and other fields requiring high-efficiency thermal control.

3. Working Principle

• Tube Side: Carries clean, treated closed circuit cooling water, used to cool essential equipment like generators, compressors, and transformers.

• Shell Side: Receives external heat removal medium, typically raw water, cooling tower water, or seawater, to absorb and carry away heat.

• Heat is transferred through the metal tube walls from the high-temperature fluid to the low-temperature one, keeping the system temperature stable.

4. Construction & Configuration

• Type: Fixed tube sheet / Floating head / U-tube design (customizable)

• Tube Material: Stainless steel (304/316L), copper alloy, titanium alloy, carbon steel with internal lining

• Shell Material: Carbon steel or stainless steel

• Design Pressure: 0.6–2.5 MPa (customized on request)

• Design Temperature: Ambient to 150℃

• Heat Exchange Area: Customizable (typical range: 5–500 m²)

• Connection Type: Flanged / Butt weld / Quick connectors

5. Key Features

1. High heat transfer efficiency – Multi-tube design with turbulence-enhancing layout improves thermal performance.

2. Compact and easy to maintain – Simple shell-and-tube structure, easy inspection and maintenance.

3. Corrosion and scaling resistance – Closed loop design helps preserve system integrity.

4. High pressure and temperature resistance – Suitable for continuous operation in harsh industrial environments.
