Reduce fuel costs by 35% and emissions by 25% with Shijiazhuang Enric’s auto CNG tanks—engineered for safety, durability, and compliance with DOT, CE, and ISO 9001 standards.
Trusted by fleets in 40+ countries, our tanks deliver 20+ years of leak-free performance under extreme conditions.
Fleet managers switching to compressed natural gas (CNG) face critical challenges that directly impact operational costs, safety, and compliance. According to the Global Gas Report 2025, global natural gas demand for transport grew by 1.9% in 2024, but substandard storage systems remain a major barrier to adoption.
Low-quality auto CNG tanks fail under pressure, leading to costly recalls and safety hazards. Poor welding or inferior materials cause micro-fractures over time, especially in high-vibration environments.
Every market has strict CNG tank standards (e.g., DOT in the U.S., ECE R110 in Europe). Non-compliant tanks risk fines, import bans, or legal liability in case of accidents.
Cheap tanks degrade within 5-7 years, requiring frequent replacements that disrupt operations. The MIT Future of Natural Gas Study notes that premature failures erase CNG’s cost advantages.
Off-the-shelf tanks often don’t fit unique vehicle frames or capacity requirements, forcing compromises on range or payload. Custom engineering is essential for optimal weight distribution.
Many suppliers disappear after delivery, leaving you with no warranty coverage or slow spare parts availability. Downtime for a single vehicle can cost $500+/day in lost revenue.
Improperly designed tanks cause uneven pressure distribution, reducing engine efficiency by 10-15%. This defeats the purpose of switching to CNG for fuel savings.
These issues don’t just increase costs—they jeopardize safety and undermine trust in your fleet’s reliability. The solution? Industry-proven auto CNG tanks built to last.
With 50+ years of experience in high-pressure gas storage, Shijiazhuang Enric Gas Equipment Co., Ltd. delivers auto CNG tanks that outperform competitors on safety, durability, and compliance. As a subsidiary of China International Marine Containers (Group), we leverage China’s world-class supply chain to offer unbeatable value without compromising quality.

Our auto CNG tanks are constructed from high-strength steel (Type 1) or lightweight aluminum-lined carbon fiber (Type 2/3/4), ensuring:
According to the IEA Global Hydrogen Review 2024, material fatigue is a leading cause of CNG tank failures. Our proprietary heat-treatment process eliminates this risk by enhancing molecular bonding in the metal.
Navigating international CNG tank regulations is complex. We simplify compliance with certifications for:
DOT (USA)
CE (EU)
ISO 9001
ECE R110
ASME
Note: We also provide local certification support for markets like India (PESO), Russia (TR CU), and Brazil (INMETRO).
No two fleets are alike. Our engineering team collaborates with you to develop bespoke auto CNG tanks tailored to:
💡 Pro Tip: For long-haul trucks, we recommend Type 4 tanks (carbon fiber-wrapped plastic liners) for their superior strength-to-weight ratio. For urban buses, Type 2 tanks (aluminum-lined steel) offer the best balance of durability and cost.

"We’ve been using Shijiazhuang Enric’s Type 2 tanks for our delivery vans for over 3 years. No issues whatsoever. The corrosion resistance is impressive—our previous supplier’s tanks rusted within a year!"
"The custom OEM design was a game-changer. Enric’s team worked with us to integrate the tanks into our waste collection trucks without sacrificing cargo space. Highly recommend!"
"As a first-time CNG adopter, I was nervous about the switch. But Enric’s Type 1 tanks were plug-and-play for our school buses. The savings on fuel paid for the tanks in under 2 years."
