Apparatus for air cooling oil
Apparatuses for air cooling of oil type АACO are designed for cooling low-pressure oil at compressor stations of main gas pipelines, as well as for condensation and cooling of vapor, gaseous and liquid media used in the technological processes of the oil and gas processing industry. Apparatuses are operated outdoors in a temperate climate with an average temperature of the coldest five-day period of at least minus 40 °С.
The device consists of one heat exchange section with chambers, blown by a stream of air, which is pumped by fans. The section is located horizontally and is mounted on a metal supporting structure along with axial fans, actuators, jalousie, diffusers, ducts.
The device is delivered in one unit in full factory readiness and does not require any assembling at the installation site.
The design of the device allows you to change the intensity of cooling by adjusting the supply of air, working fluid or stopping the fans.
