Napier

What Napier does

Napier Turbochargers is a UK-based designer, manufacturer, and aftermarket supporter of industrial turbochargers, operating from its Lincoln headquarters as a wholly-owned subsidiary of Wabtec Corporation (NYSE: WAB) since February 2013. The company produces a comprehensive product portfolio spanning 50kW to 25MW power ratings across four core lines: the NTR Series (small radial turbochargers, 50kW–2,600kW), the 7 Series (large axial turbochargers, 2MW–7MW, introduced 1998), the NT1 Series (single-stage axial turbochargers, 2MW–6MW, introduced 2014), and the NT2 Series (two-stage systems up to 25MW). Napier's technology emphasises high pressure ratios, fuel flexibility (HFO, natural gas, LNG, and future green fuels including ammonia and hydrogen), and compliance with current and future IMO diesel engine emissions requirements.

The company generates revenue through three primary streams: OEM turbocharger sales to engine manufacturers and end-users, genuine spare parts sold direct from Lincoln or through authorized distributors, and a service portfolio comprising 24/7 field service, factory overhaul/remanufacture, retrofits, and aftermarket upgrades. Napier supports a global installed base of more than 60,000 turbochargers via a network of 40+ authorized service centres across six continents, including partnerships with Wärtsilä, Caterpillar Marine, Tru-Marine, Zeppelin, and Bergen Engines. End-markets include power generation (primary), marine, oil & gas, and rail, with the Wabtec parent providing rail-market leverage and corporate-channel access. Napier maintains ISO 9001, ISO 14001, and ISO 45001 certifications, employs specialist engineers, and serves as a multi-decade incumbent in a niche where switching costs, OEM-grade spare parts supply, and a global service footprint form the basis of customer retention.
