Air coolers
AVO Horizontal air coolers AVG TU 3681-003-00220302-96
Air coolers AVG are designed for condensation and cooling of vapor, gaseous and liquid mediums used in technological processes of oil-refining, petrochemical and chemical industries.
Type of air cooler climatic version is UHL and T, placement category - I according to GOST 15150-69.
AVO air coolers 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).
Air coolers are intended for cooling mediums with outlet viscosity up to 5,10-5 m2/s (50 cSt).
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.
