What Heatex does
Heatex AB is a Sweden-based global manufacturer specializing in custom air-to-air heat exchangers for building ventilation and industrial thermal management. The company designs and produces rotary heat exchangers (Models E, ES, EN, O, ER — heat/enthalpy wheels with up to 90% recovery efficiency) and plate heat exchangers (crossflow Models H/H2/P/Z/Z2 and counterflow Model M), all custom-engineered to customer specifications rather than sold off-the-shelf. Underlying technology centers on a proprietary heat-transfer matrix combining flat and corrugated aluminum foils, with differentiated capabilities including molecular sieve coatings for moisture transfer, an AquaSeal polymer-filling process for water/air tightness, a patent-pending wheel tilt function, and a Heatex Clean Blade self-cleaning accessory.
The business model is hardware sales of custom-engineered units plus spare parts (Power Belt, brushes, motor kits), priced by quotation under multi-year supply contracts, with an OEM-oriented GTM combining direct regional sales teams and a distributor network. Primary customers are HVAC/AHU manufacturers, wind turbine OEMs (GE Renewable Energy, Goldwind, CSIC HZ Windpower, Vensys), data center cooling providers, telecom equipment makers (AT&T, Verizon, T-Mobile, Telia, NEC), EV-charger manufacturers, inverter/power-electronics producers, and electric machine builders. Manufacturing is distributed across Sweden, Czech Republic, USA, and China, and the company is owned by Madison Air, within the privately held Madison Industries group. Supporting software — Heatex Select (online configuration tool with ROI and CO2 emissions analysis), a downloadable DLL, a beta API, and an AI-powered support chatbot — extends engineering engagement into customer design workflows.
