For Purchasing Managers, Technical Directors & Operations Leaders who need reliable, compliant cylinders for natural gas, hydrogen, specialty & electronic gases.
1. Sky‑rocketing prices. 2025 data shows average cylinder cost up 15 % YoY due to raw‑material shortages.
2. Inconsistent quality. 32 % of global buyers report valve leaks or wall‑thickness deviations, leading to downtime.
3. Delivery delays. Average lead‑time for OEM‑spec cylinders stretches from 2 weeks to 6 weeks, jeopardising project schedules.
4. Regulatory headaches. Each region (EU, US, Asia‑Pacific) demands distinct CE, DOT, ISO & ATEX certifications; non‑compliance can halt shipments.
5. Hidden shipping costs. Heavy cylinders incur freight surcharges of up to $1,200 per TEU for overseas routes.
Imagine a plant shutdown because a key hydrogen cylinder failed the 5‑bar pressure test – that’s a real risk today.
Enric’s factory produces four standardized cylinder families that meet ASME, DOT, EN, ISO 9001, CE & IEC 62233 requirements. Below you will find the exact specifications, performance characteristics and typical application scenarios for each type.

| Typical Gases | Argon, Helium, Nitrogen, Hydrogen (high‑purity) | - | - |
Key Benefits: Ultra‑low out‑gassing, ISO 14644‑1 Class 5 cleanliness, and compatibility with semiconductor fabs, laser‑cutting machines and medical‑grade analyzers.
| Parameter | Value | Unit | Standard |
|---|---|---|---|
| Material | 316L SS (Austenitic) | - | ASTM A351‑F316L |
| Design Pressure | 150 | bar | EN 12279‑1 |
| Capacity | 50 | L | - |
| Operating Temp. | -196 ~ - 150 | °C | ISO 2109 |
| Insulation | Vacuum‑jacketed + 3 mm Poly‑urethane | - | - |
| Valve | Dual‑stage cryogenic valve (Stainless, 1/2” NPT) | - | - |
| Typical Gases | LNG, Liquid Hydrogen, Liquid Nitrogen, Liquid Oxygen | - | - |
Application Scenarios: Hydrogen fueling stations, LNG bunkering, cryogenic research labs, and aerospace propulsion testing. The boil‑off rate is limited to 0.1 %/day thanks to the double‑wall vacuum design.
Why Enric? Our in‑house R&D team (30+ PhDs) continuously refines wall‑thickness calculations using Finite‑Element Analysis, guaranteeing +25 % safety margin over the minimum code requirement.
The decision hinges on pressure level, temperature, purity, and mobility. Type A is best for high‑pressure bulk storage; Type B for lightweight transport; Type C for ultra‑high purity electronic gases; Type D for cryogenic liquids.
Yes. Enric offers OEM/ODM design services. We can adjust water capacity (10‑200 L), wall thickness, and provide DIN, NPT, CGA‑580, or ISO‑228 valve standards. Lead‑time for custom molds is typically 4‑6 weeks.
Each batch undergoes independent third‑party inspection (TÜV, UL, SGS). Certification documents are uploaded to our portal for instant download. We also maintain a compliance matrix updated quarterly to reflect the latest EN 13445, 49 CFR, and ATEX directives.
We ship via sea‑LCL/FCL, air‑cargo, or rail. For a 20‑ft container filled with Type A cylinders (≈ 12 t), freight from Shijiazhuang to Hamburg averages $1,850. Express air freight for 5 t of Type C cylinders is $6,200. All shipments include export‑controlled documentation (CO, SDS, CE‑DoC).
Yes. Our 24/7 technical hotline (global toll‑free) handles valve replacement, pressure‑test re‑certification, and on‑site inspection. Spare‑valve kits are stocked in Europe and North America for same‑day dispatch.
Limited‑time offer: Free 1‑month supply of sample cylinders (up to 10 L) for qualifying orders before 30 June 2026. No‑risk, money‑back guarantee if the cylinders do not pass your internal acceptance test.
