What tht ex does

THT-EX (TOP HI-TECH INC.) is a Taiwan-headquartered, privately-held manufacturer specializing in explosion-proof LED lighting and hazardous-area electrical equipment for industrial environments where flammable gases, vapors, or dusts are present. The company's product portfolio spans hazardous-location LED fixtures rated for Zone 1/2/21/22 environments, heat-resistant luminaires operating between 65°C and 120°C, marine-certified LED lighting, hazloc cable glands and junction boxes, IP cameras, speakers, sensors, and integrated visual safety systems. Its core technology platform is built around proprietary AC IN driverless LED architecture, validated through 2 million power cycle tests and extended heat-resistance qualification testing, and carries comprehensive international certifications including IECEx, ATEX, UL844 (Class I Division 1 and Division 2), ABS marine, and CR Classification Society, alongside IP66/IP67/IP68 ingress protection ratings.

The company sells primarily on a project-based B2B basis to enterprise customers in oil & gas & petrochemical, marine & offshore, chemical & industrial manufacturing, and power & energy sectors. Commercial activity is anchored around direct enterprise field sales supplemented by an international distributor network, with active market coverage in Taiwan, the USA (supported by a Houston office), the UAE, Malaysia, and Japan, and visibility at major industry trade shows (OTC, ADIPEC, OGA, Secutech, INCHEM). Revenue is generated primarily through one-time capital equipment sales, project specifications, and multi-year supply contracts rather than recurring subscription or service revenue. Recent product expansion has moved the portfolio into adjacent categories including UVC LED air disinfection systems, intelligent visual safety systems (L1920), and lighting for AI/semiconductor fabrication facilities, while the Houston office and ongoing trade show activity signal continued internationalization of the customer base.
