Our 30 kg CNG cylinders are deployed globally in:
Case Study: A U.S. logistics company switched to our 30 kg CNG cylinders for their 500-truck fleet, achieving:
➤ A 30 kg CNG cylinder holds ~50 liters of water volume (≈8-9 m³ of gas at 200 bar), ideal for light-duty vehicles, forklifts, or backup power. A 50 kg cylinder (≈80 liters) is better for heavy-duty trucks or industrial storage but weighs 20-30% more.
➤ Usable capacity = Cylinder Volume (liters) × Pressure (bar) / 10. For our 30 kg cylinder (50L at 200 bar): 50 × 200 / 10 = 1,000 liters (1 m³) of CNG (≈1.2-1.5 kg of natural gas, depending on composition).
➤ Yes! Our 30 kg type cylinders (with 300 bar pressure) are H2-ready and comply with EC 79/2009 for hydrogen storage. We also offer dedicated H2 cylinders with 700 bar ratings.
➤ 30 days for standard orders (100-500 units). For custom specifications (e.g., special coatings, valves), lead time is 45-60 days. We maintain 10,000+ cylinders in stock for urgent shipments.
➤ Yes! We provide:
➤ Per DOT/ASME standards, cylinders must be requalified every 5 years for CNG service. We offer:
Cost: $15-25 per cylinder (bulk discounts available).
