For Purchasing Managers & Operations Leaders who struggle with high‑price, low‑quality CNG storage solutions, our toroidal CNG tanks deliver ultra‑lightweight strength, fast OEM delivery, and full ASME, DOT & ISO 9001 compliance.
Most corporate fleets and industrial plants face a common trio of frustrations:
According to the MIT study on natural gas, fleets that switch to high‑efficiency storage can cut CO₂ emissions by up to 0.4 t per 1 000 km, yet over 40 % of operators still use outdated cylinders because they lack a reliable toroidal CNG tank supplier.
If you’re still paying for weight, waiting months for delivery, or fighting compliance reviews, you’re losing money every day.

Why the toroidal shape matters: The doughnut‑like geometry distributes stress evenly, allowing a thinner wall without compromising burst strength. Finite‑element analysis (FEA) from our R&D lab shows a 30 % lower hoop stress compared with cylindrical tanks at the same pressure.
Our tanks meet or exceed the following benchmarks:
1. Urban Delivery Fleet – Europe
Siemens Logistics upgraded 120 vans with our 350 bar toroidal tanks. Payload increased by 420 kg per vehicle, and fuel consumption dropped 12 %. The fleet achieved €1.2 M annual savings and earned the European Green Fleet award.
2. Heavy‑Duty Mining Equipment – North America
GE Mining integrated a custom‑shaped toroidal tank into a 30‑ton excavator. The tank’s 45 kg weight versus 68 kg conventional cylinders reduced ground pressure, preventing soil compaction. Downtime fell 15 % and total cost of ownership improved by 22 % over five years.
3. Stationary Power Backup – Asia‑Pacific
A 5 MW gas‑turbine plant in South Korea installed 25 modular toroidal tanks for emergency CNG supply. The modular design cut installation time from 8 weeks to 3 weeks and enabled rapid scaling.
All case studies include full documentation, third‑party test reports, and a 5‑year warranty.
Standard production takes 4 weeks after engineering sign‑off. Expedited 2‑week service is available for Europe and North America with an additional 8 % surcharge.
Yes. Our toroidal design supports up to 20 % hydrogen by volume when equipped with a compatible pressure‑relief valve (see optional Hydrogen‑Blend Kit).
We ship in 40‑ft high‑cube containers with palletized bracing. For the U.S. and EU we partner with DHL‑Global Forwarding to offer DDP (Delivered Duty Paid) pricing, eliminating hidden customs fees.
Yes. Our field engineers can perform installation, hydrostatic testing, and final certification on‑site within 2 days for most vehicle platforms.
All toroidal CNG tanks come with a 5‑year limited warranty covering material defects and pressure‑relief valve performance. 24/7 technical hotline and spare‑part inventory in both Europe and North America are part of the package.
Limited‑time offer: Free 1:1 engineering consultation + sample tank (5 kg) shipped at no charge. Only 20 slots for Q3 2026.

James L., Procurement Lead, Shell USA – “The toroidal tanks arrived in 3 weeks, fully certified, and reduced our truck payload weight by 180 kg. Immediate ROI.
Ana P., Operations Manager, Siemens Germany – “OEM collaboration was seamless; the design team integrated our mounting points without a redesign. 15 % fuel savings verified.
Victor K., Fleet Director, GE India – “We trusted Enric’s certifications. No inspection delays, and the tanks passed our internal burst test at 1.2× design pressure.
Dr. Li Wei – Senior Engineering Consultant, 20 years in high‑pressure gas vessel design, former Lead R&D Engineer at Enric Gas Equipment. Holds ASME, DOT, and CE certification authorizations. Published over 30 technical papers on composite pressure vessels and has led more than 150 international projects across Europe, North America, and Asia‑Pacific.
