Air coolers
AVO Zigzag air coolers with two fans 2ABZD TU 26-02-1157-96
Zigzag air coolers with two fans 2AVZD are designed for condensation and cooling of vapor, gaseous and liquid mediums (with outlet viscosity up to 5х10-5 m2/s), used in technological processes of oil-refining, petrochemical and allied chemical industries.
Climatic version type is UHL and T, placement category - I according to GOST 15150.
Air coolers (AVO) are intended for operation at temperatures and under pressure meeting the requirements of OST 26-02-1309. It is allowed to use air coolers with design pressure exceeding 2,5 MPa (25 kgf/cm2) for operation under vacuum with residual pressure up to 666,6 Pa (5mm of mercury column).
Metal carcass is designed to be used in regions with seismicity up to magnitude 7 and wind velocity head meeting the requirements of geographical region IV.
On the Customer’s request the air coolers are supplied with metal carcass designed to be used in regions with sesmicity up to magnitude 9 and wind velocity head meeting the requirements of geographical region V.
