Reduce operational costs by 15-20% with lightweight yet durable CNG cylinders. Designed for global compliance (DOT, CE, ASME) and engineered for 25+ years of service life.
Trusted by Shell, GE, and 500+ industrial partners across 40 countries
For purchasing managers and technical directors, the weight of CNG cylinders directly impacts:
Heavy cylinders reduce payload capacity by 8-12% in commercial fleets. According to the IEA Gas Market Report 2025, optimizing cylinder weight can improve vehicle range by 10-15%.
Lighter cylinders reduce structural reinforcement needs, cutting installation costs by up to 30%. Composite materials eliminate corrosion, lowering maintenance expenses by 40% over 10 years.
Non-compliant cylinders risk fines up to $50,000 (DOT) or operational shutdowns. Enric’s cylinders meet DOT, CE, ASME, and PED standards, ensuring seamless global deployment.
Poorly designed cylinders risk catastrophic failure. Enric’s Type 1-4 cylinders undergo burst tests at 2.25x working pressure and cycle testing to 15,000+ refills.
“87% of fleet operators cite cylinder weight as a top 3 consideration for CNG adoption.” – Global Gas Report 2025
