EKL

What EKL does

EKL AG is a German specialty manufacturer of thermal management solutions for the electronics industry, headquartered in Leutkirch im Allgäu. Founded in 1993, the company designs, develops, and manufactures custom and standard heat sinks, heatpipes, vapor chambers, and liquid cooling systems (cold plates) for industrial customers across sectors including industrial automation, embedded systems, medical technology, renewable energy, EV charging infrastructure, high-power LED lighting, telecommunications, power electronics, and IT/server/desktop computing. Through its Alpenföhn sub-brand, launched in 2008, EKL also serves consumer gaming and enthusiast markets with CPU air coolers and all-in-one water cooling systems.

The company operates or accesses 12 distinct heat-sink manufacturing processes — extrusion, cold forging (pin fin), soldering, bonding, swaging, friction stir welding (FSW), heatpipes, vapor chambers, crimping, skiving, die casting, and liquid cooling (cold plates). The product portfolio spans customer-specific heat sinks, embedded heat sinks, enclosure-integrated heat sinks, heatpipe heat sinks, high-performance heat sinks, LED heat sinks, PCB heat sinks, profile/extruded heat sinks, and pre-assembled modules combining heat sinks with reflectors, housings, and power supplies. EKL uses state-of-the-art thermal simulation software for virtual prototyping before physical production and runs in-house CNC production, quality control, and test laboratories at its Leutkirch headquarters.

EKL's revenue model centers on quote-based hardware sales of custom and standard heat sinks under a B2B contract structure. Sales run through a direct enterprise field-sales team led by Head of Sales Frank Sichler, supported by named account contacts and a network of European distributors including Caseking, Alternate, Reichelt, Rutronik, Bicker, Eve, and Wave Computersysteme. Manufacturing is split between German engineering and CNC production at headquarters and long-standing OEM partnerships in Taiwan and China spanning more than two decades, enabling cost-competitive production. EKL holds DEKRA ISO 9001:2015 quality management certification and AEO Authorized Economic Operator certification, sells in over 50 countries, and operates 1,100+ pallet warehouse spaces in Germany for just-in-time delivery.
