The Challenge

Keeping Fish Alive Costs More Than It Should

Holding tanks and live seafood displays depend on a constant oxygen supply. Today, most operators still rely on high-pressure cylinders or liquid oxygen — a setup with real, ongoing risk.

Sudden Oxygen Shortages

Cylinders run out without warning, causing sudden shortages and mass mortality events.

Heavy & Hazardous Logistics

Refilling and transporting pressurized cylinders is costly, labor-intensive, and carries explosion risk.

Rising, Unpredictable Costs

Ongoing purchase costs climb further in island and remote locations far from suppliers.

No Backup When Power Fails

A blackout can stop aeration entirely — with no cylinder reserve, losses can happen within hours.

The Solution

O2MOS PSA Oxygen Generator

A compact, on-site PSA oxygen solution designed specifically for live fish holding tanks. O2MOS produces high-purity oxygen on demand and supplies it continuously, simply by switching on the power. Using a high-performance zeolite adsorbent with millions of micropores, the system selectively captures nitrogen from ambient air — delivering stable, high-purity oxygen wherever it's needed, day or night.

How It Works

Core Technology — PSA System

Pressure Swing Adsorption (PSA) separates oxygen from ambient air. Zeolite beds selectively adsorb nitrogen while releasing concentrated, high-purity O₂ for immediate use.

Key Advantages

High Purity (90%+)

Consistent, medical-grade-comparable oxygen concentration.

Stable Continuous Output

Reliable pressure and flow for uninterrupted aeration.

Long Service Life

Durable components proven across years of field use.

Compact & Lightweight

Only 32kg — easy to install in tight tank-side spaces.

The Payoff

What This Means for Your Operation

Increasing dissolved oxygen significantly improves the living environment for fish — contributing directly to better overall fish quality and lower losses.

Lower Live Fish Mortality

Stable dissolved oxygen reduces stress-related die-off during holding and display.

Improved Live Fish Quality

Fresher appearance and condition for longer periods, supporting premium pricing.

No Stress at High Density or Heat

Maintains healthy DO levels even in crowded tanks or hot summer conditions.

Lower Long-Term Cost

Eliminates ongoing cylinder purchases — pays for itself over continued use.

“Blowers and pumps alone are often not enough — O2MOS is especially effective in remote and hard-to-access regions.”

Scalability

Built to Scale — From a Single Tank to a Full Facility

Multiple O2MOS units can be racked together with a booster and manifold to serve large-scale holding facilities, wholesale markets, and export operations.

Alarm & Emergency O2 Provide System

Continuously monitors output and alerts staff before oxygen levels become critical.

Booster + Manifold Distribution

Regulates pressure and flow across multiple tank zones simultaneously.

Field-Proven at Scale

Deployed in wholesale markets, processing lines, and mobile live-transport fleets.

Multi-unit rack with integrated alarm & emergency O₂ controller
