What Hitzinger does

Hitzinger Power Solutions GmbH is an Austrian-headquartered, privately-held manufacturer of precision-engineered power generation systems, founded in 1946 and operating from its production facility in Linz, Austria, with regional sales and service offices in the UK (West Malling) and the USA (Jacksonville, Florida). The company designs and manufactures synchronous alternators and frequency converters for marine, rail, military, hydro-power, and industrial customers worldwide.

The product portfolio is organised into two core families. The alternator line includes rail traction alternators (up to 6,000+ kVA), rail auxiliary power supply alternators (up to 1.0 MW), marine/naval alternators for corvettes, frigates, and yachts (up to 6,000 kVA), and horizontal and vertical hydro-power alternators (70–7,200 kVA). The converter line consists of coupled and monoshaft rotary converters for test-bay and marine shore-power applications (10–3,500 kVA) and grid-stabilisation converters with flywheel (50–600 kVA). Engineering differentiators include patented in-house display systems, a microprocessor controller with sunlight-readable glove-operable touchscreen, MTBF exceeding 50,000 hours, and service life exceeding 25 years. Marine products hold register approvals from major classification societies (LRS, GL, DNV, ABS), and the business is ISO 9001 certified.

Revenue is generated through direct enterprise sales of hardware (alternators, converters) augmented by professional services (project management, planning, testing, installation, commissioning) and recurring aftermarket support including a 24/7 service hotline, spare parts, inspection, and repair. Pricing is custom and quote-based, with multi-year contracts tied to project specifications. The customer base includes BAE Systems, Siemens, DHL, MTU (Rolls-Royce), KELAG, and ÖBB, spanning defence, rail, logistics, energy, and industrial verticals. Hitzinger operates as an independent, family-controlled private company with no disclosed institutional investors, funding rounds, or parent entity.
