Air coolers
AVO Modular air coolers AVGB 106.6055.00.000 TU
Modular air coolers of AVGB type are intended for condensation and cooling of vapor, gaseous and liquid mediums used in technological processes of oil-refining, petrochemical, gas and allied industries.
Depending on applied materials air coolers may be used at medium temperatures up to +300ºC and pressure up to 10MPa (100 kgf/cm2), including vacuum up to 655 Pa (5mm of mercury column).
On the Customers request AVGB air coolers may be manufactured for pressure 12,0 MPa (120 kgf/cm2).
The air coolers (AVO) are manufactured single and interlocking. Interlocking air coolers are intended for jointing with single or interlocking air cooler when installed into a series (in a module).
On the Customer’s request the air coolers may be equipped with:
- manually or electrically driven louver;
- heated air inner recirculation system (louver, recirculation box, wind-proof skirt) – only for air coolers with tubes 8 and 12 meters in length ;
- heated air outer recirculation system;
- mobile service platform..
