Holset HX80 Series
In production from the 1990s to 2020 for engines from 375 kW up to 840 kW and beyond, with pressure ratios up to 4.5:1, HX80 was Holset's maximum-scale fixed-geometry architecture for high-flow heavy commercial setups, still sought after by technicians servicing older ocean-going tugs and coastal cargo engines.
