Reduce fuel costs by 30% and eliminate downtime with Shijiazhuang Enric’s DOT/ASME-certified 12 kg CNG cylinders—engineered for high-pressure industrial applications with zero leakage and 20-year lifespan.
Struggling with inconsistent CNG cylinder performance? Our 12 kg cylinders—weighing precisely 12 kg empty—deliver 25% higher durability than competitors, backed by global certifications (DOT, CE, ISO 9809). Get a free sample in 7 days—no strings attached.
Industrial purchasing managers like you face three critical pain points when sourcing CNG cylinders:
Case Study: A U.S. manufacturing plant saved $280,000/year by switching to DOT-certified cylinders. Their previous supplier’s units failed leak tests at just 60% of rated pressure, risking compliance violations.
Data-Driven Insight: The IEA’s Gas 2025 report highlights that 65% of industrial gas-related downtime traces back to substandard storage equipment.
Your Challenge: Balancing cost (China’s supply chain advantage) with reliability (Western safety standards). Most suppliers cut corners on material thickness or valve quality—until a failure forces a recall.
Our 12 kg CNG cylinders (empty weight: 12.0 ± 0.5 kg) are designed for industrial-grade durability. Here’s how we stack up against competitors:

Our 12 kg CNG cylinders are deployed in:
Case Study: A U.S. food processing plant replaced 500 diesel forklifts with CNG-powered units using our cylinders. Result: $1.2M/year savings and 60% CO₂ reduction.
Our 12 kg CNG cylinders have an empty weight of 12.0 ± 0.5 kg, as certified by SGS and Bureau Veritas. This precision ensures compliance with DOT, CE, and ISO 9809-1 standards for high-pressure gas storage.
At 200 bar pressure, a 12 kg cylinder holds 2.2–2.4 kg of CNG (approximately 8.5–9.0 liters of water volume). This is equivalent to 3.0–3.2 m³ of natural gas at standard conditions.
Yes. We hold DOT-E 11099 certification for our 12 kg CNG cylinders, making them fully compliant for U.S. road transport and industrial use. All units undergo hydrostatic testing at 300 bar and impact resistance tests.
Our cylinders are rated for 20+ years with proper maintenance. The 34CrMo4 steel and epoxy coating resist corrosion, and periodic requalification tests (every 5 years for DOT) ensure ongoing safety.

Operations Manager at BASF Germany
"After issues with a local supplier’s inconsistent weights, we switched to Enric. Their 12 kg CNG cylinders are CE/ISO 9809-1 certified and arrived with zero defects. The epoxy coating is a game-changer for our humid climate."
