The BoltGuard system is a state-of-the-art, long-term bolt preload monitoring solution designed for ALK hydrogen electrolyzers. By continuously tracking bolt stress variations, it provides early warnings for critical mechanical and structural issues, such as:

· Gasket creep leading to sealing degradation

· Disc spring lock-up affecting load distribution

· Bolt stress relaxation reducing structural integrity

· Alkaline electrolyte leakage posing operational and safety risks

Key Advantages of BoltGuard

✅ Optimized for Large Bolts – Designed to ensure stable, high-fidelity signal quality, even in demanding industrial environments.

✅ Certified for Hydrogen Electrolyzers – Compliant with Ex II CT6 explosion-proof standards, making it suitable for hazardous hydrogen environments.

✅ Multi-Channel Monitoring – Capable of simultaneously monitoring up to 10 bolts, providing a comprehensive structural assessment in real time.

✅ Ultrasonic Non-Intrusive Technology – Utilizes advanced ultrasonic sensing for bolt preload assessment, ensuring zero impact on existing mechanical structures.

✅ Wireless & Battery-Powered – A fully autonomous system that enables flexible installation without the need for external power sources, reducing wiring complexity and enhancing adaptability.

By implementing BoltGuard, operators of ALK electrolyzers can achieve proactive maintenance, minimize unplanned downtime, and enhance system safety and efficiency.

The company's independently developed domestic electrolytic cell preload monitoring system features long-term continuous online monitoring capabilities, providing accurate early warning of potential problems such as gasket creep, disc spring seizure, bolt stress relaxation, and alkali leakage. Furthermore, the company has pioneered high-standard ALK electrolytic cell plate plating technology, which significantly extends the service life of the plates.

Durability: After rigorous 60-hour salt spray testing, the plated plates exhibit excellent corrosion resistance, with the surface remaining intact and free of signs of corrosion.

Safety: The company has established a rigorous quality assurance system with over ten quality inspection steps throughout the entire process, encompassing raw material inspection, production process monitoring, and finished product testing, ensuring superior product quality.

Advanced: Leveraging superior technology and strict quality control, the company offers a strong guarantee of plate performance: guaranteed to function for at least ten years, providing customers with a long-term, stable user experience.
