Serving 40+ countries | ISO 9001 Certified | 50+ Years in Gas Equipment
According to the IEA Gas Market Report 2025, industrial gas leaks cost manufacturers $20B+ annually in lost product. A single undetected hydrogen leak (100 m³/year) can waste $12,000+ at current prices.
Hydrogen leaks at concentrations >4% become explosive. The IRENA Hydrogen Safety Report notes that 60% of industrial hydrogen incidents stem from undetected leaks in storage systems.
Unplanned shutdowns for leak repairs average 8 hours in chemical plants (Source: Fortune Business Insights). Bubble testing reduces inspection time by 70% vs. electronic detectors.
Failure to meet EPA 40 CFR Part 60 (US) or ATEX Directive 2014/34/EU can result in fines up to $100,000/day. Bubble testing provides visual, auditable proof of leak-free systems for compliance documentation.
Did you know? Traditional soap bubble testing can only detect leaks down to 1×10⁻³ mbar·l/s. Our advanced bubble emission testing reaches 1000x higher sensitivity for high-purity gas applications.

Senior Engineer, Shell Global Solutions
"Enric's bubble testing reduced our cylinder rejection rate by 42% at our Houston facility. The EBT-1000 system detected micro-leaks our previous electronic sniffers missed. Their team also provided on-site training that cut our testing time in half."
R&D Director, Siemens Energy
"For our green hydrogen pilot projects in Germany, we needed a testing method that could handle 700 bar pressure while meeting EU 2014/68/EU standards. Enric's EBT-AUTO system delivered 100% reliability with zero false positives over 10,000 tests."
Bubble testing is 5–10x faster and 90% cheaper than helium mass spectrometry for most applications. While helium testing can detect leaks down to 1×10⁻¹⁰ mbar·l/s, our advanced bubble testing achieves 1×10⁻⁶ – sufficient for 95% of industrial applications (per Hydrogen Production Methods Review). Helium is better for ultra-high vacuum systems, but bubble testing is ideal for high-pressure gas storage and pipelines.
Our bubble testing solutions work with:
Note: For trace-level detection in semiconductor applications, we recommend adding a 5% helium tracer to achieve 1×10⁻⁸ mbar·l/s sensitivity.
Yes. Our bubble testing methods are:
We provide full documentation packages for audits, including test reports, calibration certificates, and operator training records.
Absolutely. Our OEM/ODM services include:

Lead time: 8–12 weeks for standard systems; 16–20 weeks for fully customized solutions.

Operations Manager, Air Products (USA)
"We switched from helium leak testing to Enric's EBT-2000 for our hydrogen trailer filling stations. The savings were immediate – $80,000/year in reduced helium costs alone. The visual confirmation also made our quality control audits much smoother."
Facility Engineer, TSMC (Taiwan)
"For semiconductor-grade gas systems, cleanliness is critical. Enric's residue-free bubble solution eliminated our post-test cleaning step, saving 2 hours per test cycle. Their custom formulation also withstood our class 100 cleanroom environment without contamination."
Maintenance Supervisor, BOC (UK)
"The EBT-AUTO system integrated seamlessly with our existing SAP PM system. The automated data logging reduced our paperwork by 70%, and the PLC interface allowed real-time monitoring. Only deduction is that the initial setup took 3 weeks instead of the promised 2."
QA Manager, Reliance Industries (India)
"In India's monsoon climate, humidity was always a problem for electronic leak detectors. Enric's bubble testing worked flawlessly in 95% humidity at our Jamnagar refinery. The local support team was also very responsive – resolved a calibration issue within 4 hours."
