Zigzag air-cooled heat exchangers with two fans type АВЗ are designed for cooling and condensation of vapor, gaseous and liquid media in the technological processes of oil refining, petrochemil and other industries. The vessel consists of six tube bays made up of finned bimetallic tubes. The tubebays are arranged in the form of a zigzag at an acute angle to each other and to a horizontal support platform. The bays are mounted on a metal structure. There is a driver with a fan impeller on a separate frame. A fan impeller while rotating in the manifold cavity, drifts the air through the tube side of a bay and thus cools the product.
