Advanced Testing Solutions for Hydrogen and Low-Flashpoint Fuels
German precision engineering specialist Sonplas has expanded its portfolio with the launch of ATEX-certified explosion-proof thermal test chambers. These units enable rigorous validation of fuel and energy system components under controlled temperature conditions in potentially explosive atmospheres.
The new chambers address growing industry demand for certified testing infrastructure as maritime operators accelerate adoption of alternative fuels, including hydrogen, ammonia, and methanol. Designed for compliance with IECEx and ATEX directives, the equipment supports temperature ranges from -40°C to +180°C while maintaining intrinsic safety in Zone 1 hazardous areas.
Key Technical Features
- ATEX/IECEx certification for Zone 1 environments
- Temperature control accuracy of ±1°C
- Modular design accommodating components up to 1m³
- Integrated data acquisition with Class I Division 2-compliant interfaces
- Nitrogen purging system for oxygen displacement
The chambers incorporate redundant safety systems including pressure relief valves, flame arrestors, and continuous gas monitoring. Sonplas has optimized the units for testing fuel cell stacks, high-pressure injectors, and cryogenic components used in emerging maritime propulsion systems.
“This development reflects our commitment to supporting the energy transition in shipping,” stated Sonplas Managing Director Dr. Markus Weber. “With these chambers, classification societies and equipment manufacturers can now conduct comprehensive performance and safety validation for next-generation fuel systems.”
Initial units have entered service at leading European maritime research facilities, with commercial availability confirmed for Q3 2024. The company reports strong pre-launch interest from LNG carrier operators and offshore wind farm maintenance providers.
