Air-cooled heat exchangers of package type АВГ-МБ are designed for cooling liquid media, as well as condensation of gas and vapor operating products. Cooling of the operating product is carried out with the air which is supplied under the supercharging upwards. The basis of vessel is the finned tubes, through which liquid or gas circulates. Tubes are combined into 4, 6 or 8 rows in a bay. The bays are fixed to a metal structure that can withstand seismic loads up to 9 points.
