Air cooled heat exchanger is a finned tube heat exchanger that uses the air for cooling medium.
It is required a wide surface area for heat transfer.
It is applied to finned tube for increasing the heat transfer surface and compact design of construction area.
An ACHE installation includes;
the finned tube heat exchanger header, steel support structure, fan drive equipment, including axial fans, V-belt drivers, bearing shafts and electric motors.
MAXWOR produces industrial air coolers that are designed to meet specific customer requirements. MAXWOR offers air coolers that vary in size, ranging from small vertical air coolers to large horizontal air coolers.
Unit configurations include forced draft, induced draft and v-type designs.
Air coolers are commonly used for cooling, compressed gas, oil and other working fluids. ACHEs are used for many Industrial Applications, such as Power, Chemical, ORC Plant, Oil & Gas, Steel Industry and many other Applications.

Forced Draft
Allows easier maintenance of the fans. Fans deliver air at ambient temperature with consequent higher efficiency. temperature differences in boiler tube.Induced Draft
The plenum chambers are mounted on top of the bundle and protect the finned surface against wind, rain, snow and partially hail. The location of the fans also ensures an optimum air distribution, limits air recirculation and allows lower level at maintenance walkway level. Fans deliver hot air.
