Air Cooled Heat Exchanger / Fin Fan Cooler
Process cooling with air as cooling medium is used successfully in many industry branches and becomes more important with steadily increasing costs for cooling water. At locations where cooling water is not available it is often the only possibility for the cooling of process streams. For the design and construction of complete air cooled heat exchanger units our engineering departments focus on the specific needs of our customers. Design and construction are carried out according to national and international standards as well as customer specifications. Through all stages of engineering we are using professional software applications. The fabrication of all FEPL ā heat exchangers is solely carried out in our workshop in Ahmedabad Gujarat which makes fabrication quality and progress traceable for our customers at all times.

Air Cooled Heat Exchanger Assembly
Air cooled heat exchangers are generally composed of the heat exchanger bundles for process cooling, the fans for the cooling air and the steel construction. Heating coils, louvers and maintenance platforms with access ladders are commonly used supplementary equipment.
Headers
Air cooled heat exchanger bundles can be equipped with different types of headers. Selection is based on the process requirements. Main criteria are the design pressure, cleaning requirements on the tube side and the requirement for access to the tube-to-tube sheet connection. Apart from the shown header types other solutions are also possible. For special applications FEPL can manufacture bundles with manifold headers, u-tubes or serpentine-coils.
Finned Tubes
Fans
The cooling air that is required for the cooling process is moved through the heat exchanger bundles by axial fans. The design of the fans and the selection of the fan type is based on the particular design point given by the heat exchanger design. Main criteria are the required volume flow of air, the pressure loss and the individual requirements regarding noise emissions.
General Assembly
The main components of an axial cooling fan are the fan ring, the fan impeller and the v-belt drive unit. Depending on the particular design requirements different blade profiles made of aluminium or glass fiber reinforced plastic (GRP) are used for the fan impellers. For the fan rings we are using a construction with an ellipsoid shape at the inlet side. This shape minimizes turbulence resulting in high energy efficiency and therefore reduced required power. Additionally noise emissions are optimized. The material for the fan rings is steel. For corrosion protection all parts are hot-dip galvanized. Alternatively painting or a combination of galvanizing and painting are possible
