Trusted by fleet operators in 40+ countries | Delivering 10,000+ units monthly | OEM/ODM customization available
As a fleet manager or automotive decision-maker, you're facing:
Skyrocketing Fuel Costs: Diesel and gasoline prices increased by 37% since 2020 (IEA Gas Market Report 2025). Natural gas offers 40-60% savings per km.
Environmental Pressures: Stricter emissions regulations (Euro 7, EPA 2027) are forcing 23% of commercial fleets to seek alternative fuels (IRENA 2022). CNG reduces CO₂ by 25% vs. gasoline.
Supply Chain Uncertainty: Geopolitical instability affects 68% of global fuel imports (IEA Q2-2026). Local CNG stations provide energy independence.
Vehicle Downtime: Gasoline/diesel engines require 3x more maintenance than CNG systems (NGV Global data). Our cylinders have 0.1% failure rate over 15 years.
Infrastructure Gaps: Only 18% of fleets have access to alternative fuel solutions (McKinsey 2024). We provide turnkey CNG conversion kits with cylinder + installation support.
Safety Concerns: Traditional fuel tanks are vulnerable to punctures. Our cylinders undergo 1.5x working pressure tests and have fire-resistant composite materials.
Solution: Our 20 kg CNG cylinders address all these pain points with proven technology and 20+ years of field data.

FAQ: Everything You Need to Know About 20 kg CNG Cylinders
❓ Q: What is the gas storage capacity of a 20 kg CNG cylinder at 200 bar?
✅ A: A 20L water volume cylinder stores approximately 5.6 m³ of CNG (≈5.6 kg) at 200 bar, equivalent to 8-9 liters of gasoline in energy content. This provides a typical sedan with 250-300 km of range.
❓ Q: How does the 20 kg CNG cylinder compare to LPG or diesel in terms of cost savings?
✅ A: Based on 2025 fuel prices:
CNG: $0.80/kg (energy equivalent)
Diesel: $1.20/liter
Gasoline: $1.10/liter
This translates to 30-40% savings vs. gasoline and 40-50% vs. diesel. For a fleet of 100 vehicles driving 50,000 km/year, this means $500,000+ annual savings.
❓ Q: What safety features are included in your 20 kg CNG cylinders?
✅ Risk-Free Guarantee: 100% refund if not satisfied with sample quality | 15-year warranty | 24/7 support

John Smith - Fleet Manager, GreenLogistics USA ⭐⭐⭐⭐⭐
We've been using Shijiazhuang Enric's 20 kg CNG cylinders for our delivery trucks for over 2 years now. The quality is outstanding—no leaks, no pressure issues, and they've held up perfectly in extreme weather. The fuel savings alone paid for the conversion in less than a year. Their team was incredibly helpful with the DOT certification process. Highly recommend!

Maria Garcia - Operations Director, EcoTrans Spain ⭐⭐⭐⭐⭐
As a European company, we were skeptical about sourcing from China, but Enric exceeded all our expectations. Their 20 kg cylinders meet ECE R110 standards and were 30% cheaper than local suppliers. Delivery was on time, and the after-sales support has been excellent. We've since placed 3 additional orders and plan to convert our entire fleet to CNG.

Ahmed Khan - CEO, CityRide India ⭐⭐⭐⭐⭐
In India's challenging conditions, most CNG cylinders fail within 5-7 years. Enric's cylinders have lasted us over 10 years with zero issues. The corrosion resistance is remarkable, and the safety features give us peace of mind. We've equipped 500+ taxis with their 20 kg cylinders, and our drivers love the smooth performance and fuel efficiency.

David Lee - Procurement Specialist, CleanFleet Australia ⭐⭐⭐⭐⭐
We needed AS/NZS 3762 certified cylinders for our Australian fleet, and Enric was one of the few suppliers who could meet our requirements. The 20 kg cylinders arrived fully certified and ready to install. The weight savings compared to steel cylinders improved our vehicle payload capacity, and the durability has been impressive. Will definitely order again.
In the UAE's extreme heat, most CNG cylinders struggle with pressure fluctuations. Enric's cylinders have performed flawlessly in 50°C+ temperatures. The thermal fuse and burst disc give us confidence in their safety. We've saved over $200,000 annually on fuel costs since switching to their 20 kg cylinders.
