Your plant needs a roof that eliminates vapor loss, cuts insurance premiums, and speeds up delivery. Enric Group delivers OEM/ODM floating‑roof tanks that meet ASME, ISO 9001, CE, and DOT standards—ready for the U.S., EU, and Asian markets.

2. High Insurance & Compliance Fees – Regulators in the EU and U.S. demand lower emissions and strict fire‑rating; non‑floating roofs trigger premium spikes of 15‑30 %.
3. Slow Delivery & Shipping Costs – Traditional steel tanks ship fully assembled, adding 2‑3 weeks and $1 200‑$1 800 per ton in freight.
4. Quality Inconsistencies – Low‑cost Chinese alternatives often miss ASME‑U‑Stamps, leading to re‑inspection delays and costly retrofits.
5. Limited Customization – Your process may need 0.2 %‑5 % oxygen‑free environments; off‑the‑shelf tanks rarely offer inline nitrogen purge or heat‑trace integration.
See the SolutionEnric Group’s floating‑roof tanks combine high‑strength carbon steel with a low‑profile aluminum‑alloy roof that floats on the liquid surface, automatically adjusting to volume changes. The result is a ≤0.1 % vapor loss, lower fire‑hazard rating, and a design that meets the most stringent global codes.

1. Hydrogen Refueling Hub – Germany
A 1 200 m³ floating‑roof tank supplied to a hydrogen‑fueling network reduced vapor loss from 0.8 % to 0.04 % and cut annual operating cost by €120 k. ROI achieved in 22 months (source: IEA Global Hydrogen Review 2025).
2. LNG Storage for a Port Facility – USA
Enric’s modular floating‑roof tank (3 000 m³) was shipped in two 40‑ft containers, saving $1 450 per ton in freight. The installation time dropped from 45 days to 12 days, enabling the client to meet a 30‑day contract deadline.
3. Specialty Gas Production – South Korea
A 250 m³ tank with nitrogen‑purge and heat‑trace kept oxygen levels <0.02 % for semiconductor‑grade argon, meeting ISO 14644‑1 clean‑room standards.
These results demonstrate how a well‑engineered storage tank floating roof can be a strategic asset, not just a container.
All Enric tanks carry ASME U‑Stamp, CE, DOT, ISO 9001, ISO 14001, and regional certifications (GS, SAA, CB). They also meet API 650/620 and EN 14015 for pressure vessels.
Yes. We offer nitrogen purge, hydrogen‑compatible seals, and low‑temperature steel grades for blue‑hydrogen projects. See our IEA hydrogen review for market relevance.
Standard models ship within 30 days after PO; OEM projects require 45‑60 days for engineering, tooling, and factory acceptance testing.
Our dedicated logistics team prepares all export documents (EXW, FOB, DDP). We hold CB and CE certificates that simplify customs clearance in EU, NA, and Asia.
24/7 technical hotline, on‑site commissioning assistance, spare‑part inventory in Europe & North America, and a 2‑year warranty covering roof mechanisms and pressure‑relief devices.
Limited‑time offer: Free 1:1 design consultation + complimentary 1‑month performance monitoring for orders placed before 31 Oct 2026.

Maria L., Purchasing Manager – Canada – “The floating‑roof design shaved 18 % off our annual vapor‑loss budget. Installation was flawless, and the after‑sales team responded within 2 hours.”
Thomas K., Technical Director – Germany – “We needed a 1 200 m³ hydrogen tank with ≤0.05 % oxygen. Enric delivered a custom‑engineered solution that passed our ISO‑14644 audit on the first try.”
Liang S., Operations Manager – Singapore – “Modular shipping saved us $2 400 in freight. The roof’s self‑leveling feature eliminated manual adjustments during seasonal volume swings.”
Emily R., VP of Supply Chain – USA – “Our compliance audit was a nightmare until we switched to Enric’s CE‑certified floating‑roof tank. Now we have a clean‑sheet audit record for three consecutive years.”
