Shell & Tube Heat Exchangers

Shell & Tube Heat Exchangers Manufacturer In UAE

National Electric Heaters LLC (NEH) is a UAE-based manufacturer and supplier of Shell & Tube Heat Exchangers, providing customized industrial heat transfer solutions for heating, cooling, condensation, and thermal processing applications.

Our shell and tube heat exchangers are designed to deliver efficient thermal performance, reliable operation, and effective heat transfer between two separate fluid circuits. NEH offers customized solutions based on thermal capacity, operating pressure, temperature, flow rate, construction materials, and industrial application requirements.

What Are Shell & Tube Heat Exchangers?

Shell and tube heat exchangers are industrial heat transfer devices consisting of a cylindrical shell containing a bundle of tubes.

One fluid flows through the tubes while another fluid circulates around the outside of the tubes within the shell. Heat transfers through the tube walls, allowing the fluids to exchange thermal energy without directly mixing.

These heat exchangers are widely used in industrial processing, HVAC systems, oil cooling, water heating, and steam applications.

Types of Shell & Tube Heat Exchangers

1. Fixed Tube Sheet Heat Exchangers

Fixed tube sheet heat exchangers feature tubes secured to stationary tube sheets. They offer a practical construction for industrial heating and cooling applications where thermal expansion and cleaning requirements are suitable.

2. U-Tube Heat Exchangers

U-tube heat exchangers use U-shaped tubes to accommodate differential thermal expansion between the shell and tube bundle. They are suitable for selected high-temperature and industrial process applications.

3. Floating Head Heat Exchangers

Floating head heat exchangers incorporate a movable tube sheet arrangement that accommodates thermal expansion and allows tube bundle removal for maintenance and cleaning.

4. Water-to-Water Heat Exchangers

Water-to-water shell and tube heat exchangers transfer thermal energy between separate water circuits. They are commonly used in HVAC systems, commercial hot water systems, and industrial process heating.

5. Oil-to-Water Heat Exchangers

Oil-to-water heat exchangers are used for cooling or heating thermal oil, hydraulic oil, lubrication oil, and other compatible industrial fluids.

6. Steam-to-Water Heat Exchangers

Steam-to-water heat exchangers use steam as a heating medium to transfer heat to water for commercial hot water generation and industrial processes.
