What Aircalo does

Aircalo (legal entity MEHITS AIRCALO FRANCE S.A.S.) is a French designer and manufacturer of climate treatment (HVAC) equipment, founded in 1958 and headquartered in Saint-Médard-en-Jalles, France. The company operates as part of the AIRCALO GROUP and reported €24 million in turnover with 8% of sales allocated to R&D. Its product portfolio spans four categories: terminal units (ducted fan-coils, fan convectors, cassettes, and electric variants), air handling units (mini AHU Mistral, compact dual-flow Fidji, modular Fidji and Lagon systems with Termibloc controls), unit heaters (hot water Onyx, gas Opal, electric Armagnac, destratifier Spot, ceiling fan Elis), and industrial generators (Aquitaine industrial condensing cabinet heaters, Make-Up direct-fired units). Energy efficiency is the central technical pillar, anchored by EC brushless motor technology with claimed savings up to 80%, the patented Sunpac and Eolis dual-energy systems that reportedly cut energy bills by 2-3x with 2-3 year ROI, Coanda-effect air diffusion in cassette units, and EUROVENT-certified performance. The company's reach extends across Europe and North Africa.

The business model is B2B enterprise equipment sales supported by an after-sales and commissioning services layer. Hardware revenue streams cover terminal units, AHUs, unit heaters, industrial generators, and replacement parts; a separate professional services stream provides on-site commissioning, performance testing, and validation for AHU, generators, and unit heaters. Commercial execution is anchored by direct regional consultant field visits combined with a network of commercial agencies across Europe, using quote-based pricing with no public list. Customer concentration spans French institutional and industrial end-markets, with named installations at marquee accounts including Airbus, Renault, Dassault Aviation, PSA Group, Thales, Galeries Lafayette, Carrefour, IKEA Bordeaux, Assemblée Nationale, Société Générale, Institut Pasteur, and luxury Paris hotels (Shangri-La, Bristol, Hyatt Vendôme), as well as healthcare institutions such as CHU Dijon and Hôpital Américain Neuilly-sur-Seine. Régis Ruelle serves as Directeur Général.

The company dedicates 8% of sales to R&D and invests in flow modeling software, production automation, digitized test facilities, and acoustic chambers. Recent activity includes a 2024-04-02 strategic investor relationship with Mitsubishi Electric Europe and continued product line extensions in the modular AHU category (s-AIRME / Lagon family).
