Air Cooled Heat Exchanger / Air Cooler Applications
ELEGANT air coolers, also called air fin coolers, are typically used in refineries, often operated together with our shell & tube heat exchangers and distillation columns. Other areas of application include the steel industry and power stations, as long as the outlet temperature is higher than the ambient air temperature.
Simple and Elegant Design
Process fluid passes through one or more tubing bundles. Heat is transferred away from the fluid through means of large fans that are either installed below (forced draft) or above (induced draft) the tubing. Aluminum fins attached to each tube enlarge the surface area of the air cooler bundle, significantly increasing the effectiveness of the heat transfer.
Benefits of Forced Draft Air Coolers
Lower energy consumption
Suitable for higher inlet temperatures
Benefits of Induced Draft Air Coolers
More even air flow across the tube bundles
No recirculation of hot air
This simple and elegant design makes ELEGANT air coolers very easy to maintain and ensures a long service life.
Why We Build Great Air Coolers
Refinery equipment is what we are good, and with many years of experience, we able to design and build every component of your refinery system, including shell and tube heat exchangers and distillation towers.
We know what is important and where the pitfalls are. This enables us to tailor each air cooled heat exchanger to your specific requirements and make sure it is delivered in full compliance with the specifications.

All Applications Covered
ELEGANT heat exchangers are used in a wide variety of applications, but we especially excel at manufacturing cooling systems for the oil processing industry.
With many years of experience in the field and our ability to design and manufacture to TEMA R, ELEGANT shell and tube heat exchangers are frequently used in refineries.
In fact, we construct and provide complete cooling systems for refineries such as finned tube air coolers.
Simple and Rigid Design
ELEGANT shell and tube heat exchangers comprise of a pressure vessel (shell) containing a bundle of tubes. The ends of the tubes are secured on a mounting plate (tube sheet) that can be either fixed to the shell or movable.
Exhaust fluid passes through the tube bundle. Heat is transferred away from the fluid by circulating a cooling medium inside the shell over the tubes. Using finned instead of bare tubes increases heat transfer by providing a larger surface area.
More than one heat exchanger may be combined to form a large single cooling unit, especially when skid-mounted.
Key Design Advantages
ELEGANT shell & tube heat exchangers combine the following key advantages:
Suitable for use in systems with high pressures and operating temperatures
Space-saving due to compact design and the ability to vertically stack several heat exchanger units.
Cost-effective, especially for large flow volumes
Shell & Tube Heat Exchanger Tube Bundle Designs
The performance of a shell and tube heat exchanger is mainly determined by the design of its tube bundle. Each design comes with a different set of advantages and limitations.
Fixed Tube Sheet
Design feature: Both tube sheets welded to the shell.
Advantages
Simple and economical design
The inside of the tubes can be cleaned
Limitation: No room for expansion of the tubes at high temperatures
U-Tube Bundle
Design Feature: Tubes bend on the shell site and fixed on a movable tube sheet on the tube side.
Advantages
Full thermal expansion of tubes possible
Tube bundle can be removed for cleaning on the outside
Limitations
Only even tube passes possible
More expensive than using a fixed tube sheet
Removable Bundle
Design Feature: The tube sheet of the rear header is not welded to the shell.
Advantages
Full thermal expansion of tubes possible
Tube bundle can be removed for cleaning on both the outside
Limitation: More expensive than using a fixed tube sheet and U-tube.
Why We Build Great Shell & Tube Heat Exchangers
We manufacture shell and heat exchangers of all TEMA types, such as BEM, CFU, and AES.
To save valuable floor space, ELEGANT S&T heat exchangers have a compact design and aim for a skid-mounted layout where possible.
With many years of experience, we know what is important and where the pitfalls are. This enables us to tailor each s&t heat exchanger to your specific requirements and make sure it is delivered in full compliance with the specifications.
