For Purchasing Managers, Technical Directors, and Operations Leaders who struggle with high‑price, low‑quality acid tanks, we deliver a proven, compliant solution that slashes inventory spend while guaranteeing safety and regulatory approval.
Get Free Quote in 24 h1. Excessive Capital Expenditure – Typical carbon‑steel or stainless‑steel tanks cost $12‑$18 per kg of capacity, pushing ROI beyond 4 years for many plants.
2. Safety & Compliance Gaps – 27 % of acid‑related incidents in Europe (2023 ECHA data) stem from inadequate corrosion‑resistant linings, leading to costly shutdowns.
3. Shipping & Logistics Overruns – International freight for 10 m³ acid containers averages $2,300 per shipment; delays add 5‑10 % extra storage fees.
4. Quality Inconsistencies – Low‑grade liners leach iron, contaminating product batches and forcing re‑processing (average loss $0.8 per kg).
5. Limited Customization – Off‑the‑shelf tanks rarely meet the 0.5 % tolerance for temperature‑drift required by semiconductor fabs.
According to the Industrial Gases Market 2025 report, manufacturers that upgrade to high‑performance acid storage see a 25 % reduction in total cost of ownership within two years.
See How We Solve These Issues →Enric’s patented “AquaGuard™ Acid Tank System” combines a triple‑layer composite (FRP‑inner, HDPE‑middle, stainless‑steel outer) with a proprietary corrosion‑inhibitor coating. The result is a storage vessel that meets ISO 9001, CE, and ASME‑U standards while delivering:
| Parameter | Value | Unit | Compliance |
|---|---|---|---|
| Design Pressure | 2.5 | MPa | ASME U, EN 13445 |
| Operating Temperature | -20 ~ 80 | °C | ISO 9001 |
| Material – Inner Liner | Fiber‑Reinforced Plastic (FRP) with PTFE coating | — | CE, RoHS |
| Material – Outer Shell | AISI 304L Stainless Steel | — | ISO 9001, ASME U |
| Corrosion Rate (H₂SO₄ 95 %) | <0.02 | mm/year | ISO 14001 |
| Maximum Fill Height | 90 | % | — |
| Certifications | ISO 9001, CE, ASME‑U, DOT‑49CFR | — | |

ISO 9001, CE, ASME‑U, DOT‑49CFR, and RoHS – all verified by third‑party labs. See our certificate gallery above.
Yes. Our engineering team offers full OEM/ODM design services, from 0.5 m³ micro‑tanks to 30 m³ bulk units, with optional instrumentation (level gauges, temperature sensors).
Standard production is 4 weeks after design approval. Expedited (express) service can deliver in 2 weeks for an additional 12 % surcharge.
All units are packed in ISO‑compatible wooden frames, equipped with UN 3211 labeling, and loaded on 40‑ft high‑cube containers. We work with DHL, MSC, and Maersk to secure temperature‑controlled routes when needed.
We provide 24 / 7 technical hotline, on‑site inspection within 30 days of installation, and a 5‑year limited warranty covering corrosion and coating defects.
Limited‑time offer: Free 1‑month trial of our corrosion‑monitoring IoT sensor (valued at $1,200) with every order placed before 31 Oct 2026. Risk‑free – if you’re not satisfied, we’ll refund the sensor cost.
