Induced Draft Air cooled Heat Exchanger ACHE The second most economical and most common style air cooler is the induced draft ACHE. This design uses axial fans to pull air across the fin tube bundle. The fans are positioned above the bundle thus offering greater control of the process fluid and bundle protection due to the additional structure.
APPLICATIONS:Oil & Gas, Petrochemicals, Chemicals etc. MATERIALS:Carbon Steel, Stainless Steel & other Exotic Alloys. Jord designed & manufactured Air Cooled Heat Exchanger are cooling many critical processes such as Natural Gas, Sour Water, LPG, Naphta, Diesel etc. All our ACHE units are designed as per API 661 & client specifications.

Air Cooled Heat Exchangers Air Cooled Exchanger DesignInduced draft air-cooled heat exchangers Induced draft air-cooled exchangers have fans located above the bundle and air is pulled across the finned tube surface. This arrangement provides a more even distribution of air due to lower air velocity.
An air cooled heat exchanger (air cooler) removes heat from a liquid or gas into ambient air. Chart provides horizontal, vertical and multiple fan coolers with both forced and induced draft. Complete range of options including winterization, maintenance and header walkways, ladders, bugscreens, louvers, heating coils and warm air recirculation. Air-cooled Heat Exchangers:Forced vs. Induced DraftAir-cooled heat exchangers are classified as forced draft when the tube section is located on the discharge side of the fan, or induced draft when the tube section is
There are two main designs of air cooled heat exchanger. Forced draft and induced draft styles. Forced draft heat exchangers are usually less expensive to manufacture to achieve the same amount of cooling power. This is due mainly to the fact that induced draft coolers require more structural support and components per kilowatt of cooling power. Forced and Induced Draft air-cooled heat exchangers - Induced draft air cooled heat exchangers Fans are located above the bundle Air is pulled across the finned tube surface Since air velocity approaching the bundle is relatively low, it provides more even distribution of air across the bundle
The induced draft configuration positions the fans above the exchanger bundle. High velocity hot air exhaust reduces the risk of hot air recirculation, and plenums protect the exchanger bundle from the elements. Induced draft exchangers are well suited for lower process temperatures and for applications where hot air recirculation is a concern. Induced Draft Air Cooled Heat Exchangers - ThomasnetManufacturers rep. of air cooled induced draft heat exchangers made from stainless steel. Specifications of air cooled induced draft heat exchangers include 1,500 degrees F operating temperature, 100 cfm to 10,000 cfm volume range, 12 in., 36 in., 42 in. & 48 in. plate size & 50 in., 74 in. & 98 in. unit length.
Induced draft air cooled heat exchangers pull air from below a fin tube bundle, through and around the fins then past the fan blades, exhausting above the unit. In this design the fans are mounted above the fin tube bundle. The drive motor may be mounted above the fans where the cooling requirement is low and exhaust air will be relatively cool. In most cases the motors and drivetrain are mounted below
