Why Your Current Containment Strategy Is Costing You

Leak‑related incidents have risen 27% in the last three years across North America and Europe, according to the IEA Gas 2025 report. The fallout is three‑fold:

Regulatory fines – Up to USD 500,000 per breach under EU ATEX 2014/34 and US OSHA 29 CFR 1910.119.
Production downtime – Average 4.2 days lost per incident, translating to $1.2 M in lost revenue for a mid‑size plant.
Brand damage – 68% of B2B buyers consider safety records when selecting a supplier (Fortune Business Insights, 2025).

In addition, high‑price, low‑quality secondary containment solutions from “cheap‑China” suppliers often arrive late, requiring costly retrofits. The result? Higher total cost of ownership (TCO) and a fragile supply chain.

Discover a Proven Containment System

The Enric Secondary Containment System – Your Safety Net

Our secondary containment combines a double‑wall pressure vessel, integrated leak‑detection sensors, and a certified spill‑catch basin that meets CE, ISO 9001, ASME, DOT, and FCC standards. Designed for natural gas, hydrogen, and specialty gases, it delivers:

99.999% leak‑tight performance under 150 bar operating pressure.
Modular OEM/ODM design – fits existing pipelines without major shutdowns.
Fast‑track delivery – 2‑week lead time from order to site, thanks to our in‑house CNC and welding lines.
Smart monitoring – real‑time data via MQTT, compatible with SAP PM and SCADA.

Frequently Asked Questions

What exactly is secondary containment for gases?

It is a **redundant, leak‑tight barrier** that surrounds the primary vessel or pipeline, designed to capture any accidental release and direct it to a safe collection system, complying with ATEX, OSHA, and IEC safety codes.

Can the system be customized for different gases?

Yes. We offer **OEM/ODM** options for hydrogen, nitrogen, oxygen, specialty gases, and even blended mixtures. Material selection (e.g., 316L stainless, Hastelloy C‑276) and sensor calibration are tailored per client specifications.

What is the typical lead time and shipping method?

Standard modules ship within **14 days** from PO confirmation via **FOB Shanghai** or **CIF New York**. Expedited air freight is available for critical projects (additional 20% cost).

Compressor Natural Gas

How is after‑sales support handled?

We provide a 24 / 7 technical hotline, on‑site commissioning engineers, and a 5‑year warranty covering material defects and sensor calibration. Spare‑part kits are stocked in both Europe and North America.

Is the system compatible with existing SCADA platforms?

Our sensors support **Modbus TCP**, **OPC-UA**, and **MQTT**, allowing seamless integration with Siemens, ABB, and Rockwell automation suites.
