Purchasing managers and station operators face these daily challenges with subpar CNG cascades:
Traditional cascades take 8-12 minutes to refuel a standard vehicle. Our solution: 4-6 minutes with optimized flow dynamics (validated by IEA Gas 2025 Report).
Leakages, pressure surges, and material fatigue cause 1 in 5 station downtimes (Source: IGU Global Gas Report 2025). Our solution: Triple safety valves + real-time pressure monitoring.
Cheap cascades corrode within 5 years, requiring costly replacements. Our solution: Stainless steel 304/316L construction with anti-corrosion coating for 15+ year lifespan.
Failed certifications delay 60% of international shipments. Our solution: Pre-certified for ASME, DOT, CE, TPED, CCC—no retesting needed.
Standard lead times: 12-16 weeks. Our solution: 15-day express delivery from our 50,000 m² factory in Shijiazhuang.
One-size-fits-all designs force costly workarounds. Our solution: OEM/ODM—custom pressure ratings, port configurations, and branding.
Shijiazhuang Enric Gas Equipment’s CNG cascades are engineered for high-flow, high-pressure natural gas storage and dispensing, optimized for retail, fleet, and industrial refueling stations. With 40+ years of experience and 1,200+ global installations, we deliver:

✅ A CNG cascade is a multi-cylinder storage system that stores compressed natural gas at high pressure (typically 200-300 bar). It uses multiple stages to efficiently transfer gas to vehicles at the required pressure, ensuring fast, consistent refueling.
✅ Our cascades refuel a standard sedan in 4-6 minutes and a bus/truck in 8-10 minutes. This is 30-40% faster than traditional systems due to our patented pressure equalization technology.
✅ Yes. We hold DOT (USA), CE/TPED (EU), CCC (China), PESO (India), and other regional certifications. All units are pre-tested and pre-certified for the target market.
✅ Absolutely. We offer full OEM/ODM services, including:
Minimum order quantity (MOQ): 1 unit for standard models; 5 units for full customization.
✅ 15 days for standard models (in stock). 30-45 days for custom orders. Express shipping available for urgent projects.
