ABB VTR 320/321
Genuine ABB VTR 320/321 turbocharger units and spare parts. Tested, reconditioned, and OEM-grade parts available worldwide.
High-capacity ABB VTR 320 series turbocharger for large 2-stroke engines. The 321 denotes the updated variant with improved blade geometry for better surge margin.
Role in the Vessel
Turbochargers recover energy from exhaust gases to pre-compress intake air, increasing charge air density and enabling the engine to burn more fuel per cycle. A well-maintained turbocharger can improve specific fuel oil consumption by 30-40% compared to a naturally aspirated engine, making it the single most important auxiliary component on a marine diesel engine.
Common Issues Requiring Parts or Overhaul
Compressor and turbine wheel fouling from salt air deposits and combustion residues reducing efficiency, bearing failure from contaminated or degraded lubricating oil, rotor imbalance from deposit build-up causing vibration and bearing overload, surging from fouled charge air coolers or excessive exhaust back-pressure, oil leakage from worn shaft seal labyrinth packings into the air or exhaust stream.
