WELCO INDUSTRIES

What WELCO INDUSTRIES does

WELCO Industries is a French family-owned private manufacturer of custom motor-compressors and electric motors engineered for mission-critical cooling applications. Founded in 1976 with roots in a 1968 U.S. predecessor, the company operates from a 1,000 m² facility in Le Poët, France, and is led by CEO Charlotte Bourgeois, in role since 2011. Its quality system is certified to ISO 9001:2015 and the aerospace-specific EN 9100:2018 standard, and WELCO has filed for PART21G production organization approval in 2025.

The core product portfolio spans hermetic scroll, rotary vane, and piston compressors in the 150 W–25 kW range; AC and DC electric motors from 100 W to 20 kW; supporting fans, blowers, and pumps; and electronic drive and control-command systems. The stated technical differentiator is a proprietary direct-drive motor-compressor architecture claimed to be approximately 30% lighter than conventional alternatives, with build-to-order production accepting no minimum order quantities. This combination enables low-volume, custom-configured series for OEM programs where off-the-shelf units are unsuitable.

WELCO sells directly to global aerospace, naval, and military OEMs and tier-one integrators, with a publicly visible customer set that includes Dassault Aviation, Honeywell Secan, Thales Air Systems, Ipeco, Aerolux, Safran, Airbus Helicopters, Israel Military Industries, Ametek, Noske Kaeser, Tyonek, Tekgard, Aviosystem, Josun Air Conditioning, and CAP II. Revenue is generated via direct custom-manufacturing contracts with these primes rather than through distribution channels, and the company has leveraged French regional and national support programs (Pégase Croissance in 2016; France Relance in 2020) to underwrite product and certification investment.
