Zigzag 2AVZD air cooling units with heated air regulation with two fans
Designed for condensation and cooling of vaporous, gaseous and liquid media in technological processes of oil refining, petrochemical and related industries.
The device consists of six tube sections made up of bimetallic finned tubes. The sections are arranged in a zigzag pattern. Sections are mounted on a metal structure.
A drive with a fan wheel is placed on a separate frame.
The device is equipped with a heated air recirculation system, which allows for more accurate technological parameters at a wide range of ambient temperatures, as well as to prevent overcooling of the product at low ambient temperatures.
The recirculation system can be supplied separately.
