What ElectroAir does

ElectroAir is a privately-held Estonian manufacturer of ground support equipment (GSE) and aircraft power systems, founded in 2006 and headquartered in Rae parish, Estonia, where it operates a >16,000 m² production facility. The company designs, manufactures, and services a comprehensive portfolio of Ground Power Units (GPUs) spanning diesel-driven (APA-65, APA-100, APA-110, APA-150, APA-165), plug-in hybrid (APA-65 EACR-45/600 co-developed with Airbus Helicopters, APA-10), and battery-powered LiFePO4 (APA-ECO 190/320) configurations, all delivering 28.5 VDC and/or 400 Hz AC output. The product range extends beyond GPUs to frequency converters (EAC series), 28.5 VDC rectifiers (EAR series), combined AC+DC power units (EACR series), gas charging systems (nitrogen, oxygen, air servicer), hydraulic power units, air starter units, PIT hatch systems, load banks, cable management, distribution pillars, and adjacent offerings in marine shore power, EV charging (EACharger Gen 4.0), and battery energy storage (EA-BESS).

Underlying technology is anchored in static frequency converter (SFC) architectures with proprietary MPCU microprocessor controllers, automatic line drop compensation on cables up to 50 m, IP55 enclosures operating from -40°C to +55°C, MIL/CIV dual compatibility, and a modular 15-minute mean-time-to-repair design. The company holds AQAP 2110 NATO certification alongside ISO 9001, ISO 14001, and ISO 45001. It employs 100+ professionals and reports serving 500+ customers in 100+ countries across airports, airlines, MROs, ground handlers, and defense operators.

The business model is industrial B2B direct sales supplemented by an international distributor network and industry exhibitions (Inter Airport Europe, Americas GHI Conference, Supply Security & Defence Expo). Revenue is generated primarily through custom-engineered hardware sales with per-project quotations (premium units priced at €500,000+ for high-capacity dual-output diesel GPUs), complemented by commissioning, training, and annual service contracts priced below 10% of equipment cost. Non-dilutive co-financing from Enterprise Estonia under the European Regional Development Fund (approximately €631K across EA-BESS and EA-Charger Gen 4.0 projects) supports product development without equity dilution.
