SU Group Secures Exclusive Distribution Rights for Portable X-Ray System in Hong Kong and Macau
Second International Distribution Deal of 2026 Gives SU Group a Foothold in the Critical Industrial Inspection Market
HONG KONG, September 15, 2026 – SU Group Holdings Limited (Nasdaq: SUGP) (“SU Group” or the “Company”), an integrated security-related engineering services company in Hong Kong, today announced the award of an exclusive distributorship of TRACELINE™ PX3 Portable X-Ray System (“PX3”) by HDX.
SU Group is now the sole authorized distributor of HDX's flagship portable X-ray system in Hong Kong and Macau, marking SU Group’s second international distribution agreement this year, following its June partnership with Germany's GEZE. The TRACELINE PX3 is built for Explosive Ordnance Disposal (EOD), Technical Surveillance Counter-Measures (TSCM), fire investigation, and industrial Non-Destructive Testing (NDT), all mission-critical fields where reliability commands a premium.
Unlike traditional X-ray systems, which tend to be bulky, power-hungry, and reliant on continuous radiation sources, the TRACELINE PX3 was purpose-built for the mobility and precision that modern inspection work demands. More information on the system is available here: TRACELINE PX3 Portable X-Ray System.
TRACELINE PX3-S is a complete, field-ready inspection kit that combines digital radiography (DR) imaging, a low-dose pulsed X-ray source, and advanced digital image processing in a single lightweight unit. Key advantages include:
- Flash Imaging Speed. A pulsed X-ray source firing microsecond bursts captures sharp, high-energy images in an instant, even in dynamic conditions.
- Built to Take a Hit. A compact, IP54-rated design withstands harsh operating environments without sacrificing portability or performance.
- Safe by Design. Pulsed X-ray technology cuts radiation exposure by more than 70% compared with continuous-source systems, while also reducing power draw.
Dave Chan, Chairman and CEO of SU Group, commented, “This agreement further strengthens our comprehensive solutions portfolio with a dedicated platform to compete in industrial markets. TRACELINE PX3 is exactly the kind of technology our security and engineering customers have been asking for: fast, safe, low power and field-ready. More importantly, it gives us a credible entry into industrial inspection, a market with its own attractive growth trajectory and margin profile. We intend to move quickly to convert this meaningful opportunity into value for shareholders.”
