Zigzag air cooling units 2AVZ-D
These units are designed for cooling and condensation of vaporous, gaseous and liquid media in the oil refining, petrochemical and related industries. The unit consists of six pipe sections made up of bimetallic finned pipes. The sections are arranged in a zigzag shape at an acute angle to each other and to the horizontal support platform. The sections are mounted on a metal structure. A drive with a fan wheel is placed on a separate frame. The fan wheel, rotating in the collector cavity, drives air through the inter-tube space of the sections, cooling the product.
