Air Cooled Heat Exchangers


The principle component of an Air Cooled heat Exchangers is the tube bundle, of which there may be many, normally comprising finned tubes terminating in header boxes.It also known as Fin Fan heat exchangers are typically used in applications where water is not available or the desired process outlet temperature can be achieved given the maximum ambient temperatures. Also, air cooled equipment can be a more simple solution against water cooled because in water cooled systems there is also a need for more pumps, piping, central chiller or cooling towers increasing the operating cost and maintenance of the system.Air Cooled Heat Exchangers are used in a wide variety of applications. Common air to liquid applications include but are not limited to lube oil coolers, water and glycol coolers, jacket water coolers, engine radiators, hydraulic oil coolers (both stationary and mobile), and closed loop cooling systems. Common air to air or air to gas applications include but are not limited to inter/aftercoolers on compressors, belt guard after-coolers, blower coolers, biogas cooling, landfill gas cooling, soil vapor extraction, and a wide variety of condensing applications.With our vast knowledge and expertise in a wide range of industries and markets we can help put you in the most cost effective and efficient option available.Fan Driven units are shipped with electric motors suitable for indoor and outdoor applications although alternate motors are available upon request, i.e. hydraulic, air, and engine driven.We not only provide equipment with copper tubes / aluminum fins or furnace brazed Aluminum surface, we can also provide coils with carbon steel, or stainless construction including the headers, tubes and fins.

An Air Cooled Heat Exchangers is a large piece of equipment compared to other types of heat exchangers, and requires free space around it for the cooling air flow. In refineries and chemical plants Air Cooled Heat Exchangers are usually mounted over a piperack, saving plot space at grade and ensuring free airflow. A further advantage of this elevated mounting is shorter pipe runs for column overheads, saving both cost and pressure drop. In some cases an ACHE may be mounted on top of a column to keep pressure loss to an absolute minimum, but this can make maintenance more difficult.
