ERETEC

What ERETEC does

ERETEC (이레테크) is a South Korean provider of Electromagnetic Compatibility (EMC) testing and measurement solutions, headquartered in Gunpo-si, Gyeonggi-do. The company designs, manufactures, and integrates anechoic chambers across military, automotive, commercial, and special-purpose applications, alongside EMC test systems (EMI/EMS/TRS), antenna test systems (OTA, MIMO, RSE), and supporting instrumentation including ESD simulators, RF amplifiers, and CDN/clamp devices. It also distributes the TESEQ product line from AMETEK CTS, indicating a hybrid manufacturer-distributor model with both proprietary hardware and resale revenue streams.

The company's software portfolio includes EMINT, an AI-powered EMI countermeasure assistance platform, and TOYO-branded analysis software. Its customer base spans defense and military, automotive electronics (with stated emphasis on EVs and autonomous driving systems), and commercial/civilian sectors, with a stated partnership with KATECH (Korea Automotive Technology Institute) for next-generation vehicle EMC testing. Revenue is generated through hardware sales (chambers and test equipment), software licensing, and professional EMC testing services. The company has signaled international expansion ambitions through participation in EMC China 2025 and has been recognized by the Korean Ministry of SMEs and Startups as a 2026 Global Strong Company.

The company's strategic positioning is reinforced by a forthcoming spin-off of a DataLabs entity (effective January 1, 2026), suggesting internal restructuring to separate software/data initiatives from the core EMC hardware business. The product launch of EMC Test Automation Solutions in December 2025 indicates a shift toward software-driven, higher-margin offerings within the EMC testing workflow. Headcount is reported at 1–10 employees, indicating a very small operating footprint relative to the technical breadth claimed across chambers, instruments, and AI software.
