What Cotes does

Cotes A/S is a Danish privately-held manufacturer of industrial adsorption dehumidifiers, headquartered in Viby J, Aarhus, with 101–250 employees and operating since 1986. The company's core technology is rotor-based adsorption dehumidification using silica gel wheels, delivered through a broad product portfolio that includes mobile units (CR80B–CR400B), wind-turbine retrofit units, modular industrial systems (C30E through C105E), cold-store units (C30C–C65C), hybrid condensation-adsorption units (CH22, CH26), standard flexible high-capacity systems (C125–C194), and the Cotes Ultradry line for ultra-low dew point applications. Its patented Cotes Exergic Technology is a three-rotor system achieving cumulative 99.9% moisture removal and enabling regeneration using hot water at 80–90°C, reducing energy consumption in lithium-ion battery dry rooms by 30–40% (up to 92% in some scenarios) and allowing integration of sustainable heat sources such as waste heat, district heating, biomass, solar thermal, and CO₂ heat pumps.

Cotes sells directly to Wind Energy and Lithium-Ion Battery Manufacturing customers globally and routes all other verticals through a Global Partner Network covering 20+ countries and 26+ regions across Europe, Asia, and Africa. Revenue is generated primarily through hardware sales of dehumidifier units, modules and accessories (Heat Recovery, Condensation/LK, Window Kits, controllers, hygrostats), and spare parts serviced through the partner network, with pricing provided via quotation rather than public disclosure. The company claims over 85% global market share in offshore wind turbine dehumidification and more than 20 years of wind-industry experience, while also serving food & beverage, waterworks, paper & printing, heritage preservation, hydropower, and water-damage restoration customers.

Operational differentiation rests on proprietary IP (Exergic three-rotor system, Cotes Wind Overpressure solution, Window Kit), long product lifespans (cited around 40,000 operational hours), and vertical specialization with dedicated product families for each major use case. The firm is ISO 9001 and ISO 14001 certified, a member of APQP4wind, and won the Red Dot Award 2025 and German Design Award 2026 for the CL26 lightweight dehumidifier developed in collaboration with Produktdesignerne.
