“Enric’s CNG cylinders cut our fuel cost by 30 % while the ISO‑9001 audit showed zero non‑conformities. The on‑site monitoring dashboard reduced downtime by 15 %.”
Laura Chen, Operations Manager – Siemens AG
“The custom‑engineered 350 L cylinders fit our electric‑assist trucks perfectly. Certification under CE and ASME U‑St‑1 gave us confidence to roll out fleet‑wide within 3 months.”
CNG = Compressed Natural Gas. It is stored at 200 bar in high‑pressure steel cylinders, whereas LNG (Liquefied Natural Gas) is cooled to –162 °C and stored in cryogenic tanks. CNG is ideal for on‑site refueling and short‑haul transport; LNG is used for long‑distance shipping and large‑scale power generation.
Yes. Most Class 8 diesel engines can be retrofitted with a CNG fuel system (injector, pressure regulator, and ECU mapping). Enric offers OEM‑grade conversion kits that meet DOT‑49 and EPA 2026 emission standards. Typical conversion cost: US $12,000–$18,000 per vehicle, with a payback period of 2–3 years based on a 25 % fuel‑price differential.
Key certifications include ISO 1519 (cylinder design), ASME U‑St‑1 (pressure vessel), DOT‑49 (U.S. transport), CE (EU market), and RoHS (material safety). Enric’s factories hold all these certificates, and each cylinder carries a permanent laser‑etched serial number for traceability.

Our turnkey solution includes a mobile on‑site compressor (up to 1 000 Nm³/h), a bulk storage tank, and a dispenser with RFID‑enabled cylinder tracking. The system complies with ISO 9809 for bulk storage and can be powered by grid electricity or onsite solar, aligning with the IEA Global Hydrogen Review 2025 recommendation for hybrid gas‑hydrogen infrastructure.
Based on the MIT “Future of Natural Gas” study (2011) and the 2025 IEA “Gas 2025” outlook, a 100‑vehicle fleet converting to CNG can achieve a 25‑30 % reduction in fuel spend and a 15‑20 % reduction in CO₂ emissions. With a 5‑year depreciation schedule, the internal rate of return (IRR) typically ranges from 12 % to 18 %.
Limited‑time offer: Free 1‑month trial cylinder (120 L) + money‑back guarantee if fuel savings < 15 % after 90 days.
