Aeristech Limited

What Aeristech Limited does

Aeristech (legally RGW Consulting Ltd, trading as Aeristech) is a UK-based engineering firm headquartered in Leamington Spa, Warwickshire, that designs and manufactures patented high-speed permanent magnet variable speed electric motors and oil-free air-bearing compressors. Its core technology spans speeds up to 160 krpm, power ranges of 2.4–40 kW, and voltages from 9 V to 800 V, packaged into products including 12 V and 48 V eSuperchargers for automotive turbo lag mitigation, single- and two-stage oil-free turbo-compressors (AeC818L-9, AeC815L-11), a 3-stage centrifugal industrial compressor system, and the NovA e-compressor platform targeting 150+ kW heavy-duty fuel cell installations. The company serves enterprise automotive OEMs and Tier 1 suppliers (BMW, Volkswagen, Cummins, GKN), industrial air and HVAC customers, and hydrogen fuel cell system integrators in commercial vehicle, aerospace, and public transit applications.

Aeristech earns revenue through a mix of direct B2B hardware sales (eSuperchargers and oil-free compressors sold quote-by-quote to OEM engineering teams), tailored consultancy services (machine design, air-bearing integration, characterisation testing), and prototype/short-run manufacturing (magnet machining, precision grinding, rotor assembly, balancing). Go-to-market is exclusively enterprise field sales, supported by conference exhibitions (CenexExpo, Future Propulsion Conference), a UK Government Pavilion showcase, and co-development partnerships enabled by APC UK government funding. The business maintains engineering and business development offices in China and the USA in addition to its Warwickshire HQ, and its IP estate (formerly held by Aeristech Limited) is now consolidated under RGW Consulting Ltd.

The company is small (11–50 employees), privately held, and operates without disclosed institutional backing beyond a limited set of equity rounds (Midven/Minerva in 2010, Angels/SyndicateRoom in 2014) and ongoing non-dilutive APC UK programme funding. Recognition includes the 2019 Institute of Physics Business Innovation Award, the Queen's Awards for Enterprise, and UKAS ISO 9001 certification for its underlying technology.
