Serie VG

Questi package di compressione e trattamento del gas secco sono progettati su uno skid facilmente movimentabile composto da un gruppo di compressione rotativo a vite a iniezione di olio direttamente accoppiato grazie ad un giunto flessibile o magnetico ad un motore elettrico controllato da inverter.
• VG: pressioni operative da 3,0 bar(g) a 25,0 bar(g).

COME FUNZIONA
Il gas secco viene aspirato da un filtro di aspirazione di tipo grossolano per poi passare attraverso una valvola di controllo dell’aspirazione. Durante il processo di compressione del gas, l’olio viene iniettato all’interno del pompante per svolgere tre funzioni principali: lubrificazione, tenuta e assorbimento del calore. Attraverso una valvola di minima pressione/non ritorno, il gas passa in un raffreddatore ad aria o ad acqua. Una valvola meccanica di by-pass ricircola il gas in eccesso in aspirazione per modulare la portata dal valore raggiunto alla minima velocità del motore elettrico, fino allo 0%. A volte è necessario installare una valvola di by-pass pneumatica o elettrica per avere un controllo più accurato. Quando il sistema si ferma, il gas viene depressurizzato immettendolo in un apposito serbatoio di espansione o facendolo disperdere nell’atmosfera.

fino a 40 bar(g)
