ABB VTR Series Turbocharger Gas Inlet Casing 0.5-18 m³/s Flow Range 2.0-4.0 Compression Ratio for Marine Diesel Engines

The VTR series turbocharger is an axial-flow design consisting of single-stage axial-flow turbine and centrifugal compressor. It utilizes outboard support roller bearing and self-supply system with shaft-end centrifugal lube oil pump or gear lube oil pump. The major casing can rotate freely in 15° or 30° intervals according to installation requirements.
