Lube oil air-cooled heat exchangers oil type АВО-М are designed for cooling and condensation of gaseous, vapor and liquid products in the technological processes of oil refining, petrochemical, gas and related industries. The field of application is the cooling of low-pressure oil at compressor stations of main gas pipelines. Heat exchangers are designed to replace ones of Hungarian origin with horizontal arrangement of heat-exchangingbays installed on supporting metal structures.
