What NADA does

NADA Co., Ltd. (주식회사 나다) is a privately held South Korean company founded in 1997 that designs and manufactures AI-based vibration monitoring and diagnostic systems for critical rotating machinery. Its portfolio spans online monitoring systems (V-net7000A/B for turbines, CMS for general industrial assets, QMS for quality control, TSI for API670-compliant turbine protection), portable instruments (VibLow7000 multi-channel analyzer, VibLow CXII Plus, automated calibration and laser shaft alignment systems), and a sensor line (Smart Works wireless accelerometers, eddy current proximity probes, piezoelectric accelerometers). Underpinning these products is a proprietary AI engine and self-evolving Big Data Platform, exposed through the NADA Digital Twin System and an AI-based Smart Factory Solutions cloud platform supporting 24/7 predictive maintenance over 5G/LTE.

NADA monetizes primarily through one-time hardware/system sales and professional services (engineering, acceptance testing, predictive maintenance consulting), with a supplementary training revenue stream from ISO18436-2 certified Categories I-IV courses priced at 700,000–1,200,000 KRW per session. The company serves enterprise customers across power generation (KHNP, Korea East-West Power), nuclear export projects (Turkey Akkuyu, Egypt El-Dabaa), heavy industry (POSCO, Hyundai Motor, Hankook Tire, Samsung SDI), oil & gas (Saudi Aramco, ONGC), shipbuilding (Samsung Heavy Industries), and defense (Republic of Korea Navy). Distribution runs through three wholly-owned subsidiaries (USA, China, India), regional distributors in five additional countries, and direct sales from the Pangyo Innovation Lab headquarters in Seongnam, South Korea.

The business model is enterprise field-sales driven with high regulatory qualification requirements, particularly in nuclear power where NADA holds KHNP Qualified Supplier status, Rosatom Register certification (Russia, 2022), and NDK certification (Turkey, 2022), plus SIL-2 on its VMS. The company has accumulated seven granted patents covering wind turbine diagnostics, naval propulsion monitoring, and spectrum-based fault detection, and has trained approximately 5,000 professionals since 2007 through its ISO18436-2 program.
