What Wesper does
Wesper Air Thermik is a privately held French industrial manufacturer of air treatment, heating, cooling, and refrigeration systems, headquartered in Pons, France (Nouvelle-Aquitaine). The company has manufactured centrales de traitement d'air (air handling units) since its founding in 1948 and has grown through two strategic acquisitions: Géothermik (including Multiclima) in 2005 and Climasol (from the Wavin group) in 2013, which added air-to-water monobloc heat pump manufacturing capabilities for residential, industrial, and public-sector customers.
Wesper's core product portfolio comprises air handling units (its foundational line), industrial and residential dehumidifiers, air-to-water heat pumps produced by the sister companies Géothermik and Climasol, and custom-manufactured batteries à ailettes (finned coils). The company also recently entered the dehumidification market as a consolidated offering, leveraging the combined expertise of its acquired sister companies. All products are developed, assembled, and manufactured in France through Wesper's own R&D service.
The business operates a B2B go-to-market targeting industrial clients, businesses, and public institutions, with a dedicated "Espace Pro" (professional access) portal on its website. Pricing is quote-based and not publicly disclosed, consistent with project-driven industrial HVAC sales. The company is constituted of private shareholders, has 11-50 employees, and maintains a domestic-only operating footprint centered on Nouvelle-Aquitaine, with no disclosed international expansion. Marketing is conducted through corporate websites (wesper.com, wesper.net), LinkedIn and Facebook pages, and downloadable PDF product catalogs (e.g., Gamme Wesper 2026).
