Product Overview

Why a Vehicle-Mounted PSA Oxygen Generator

  1. Purpose-Built for Live Haulage

    Delivers a dedicated, continuous oxygen supply to live fish transport trucks of every size.

  2. Oxygen On Demand

    Generates oxygen directly from ambient air — no refilling, no transporting or storing bulk oxygen.

  3. Lower Cost, Same Reliability

    A cost-saving, convenient alternative to liquid oxygen (LOX) and high-pressure cylinders.

  4. Lighter, More Efficient

    Cuts vehicle weight by over 200 kg versus LOX or cylinder systems, reducing fuel costs.

  5. Low Cost of Ownership

    Low maintenance requirements keep day-to-day operating cost to a minimum.

Market Context

A Growing Need for Reliable Live Fish Transport

Market Overview

  • Growing demand for live fish logistics across Asia and India.
  • Increasing transport distances that require stable, dependable oxygen management.
  • Rising costs of liquid oxygen and its refilling logistics.
  • A clear market shift toward smart, safe, and low-maintenance oxygen solutions.

Why It Matters

Getting fish to consumers alive and in top condition is one of the fisheries industry's central challenges — poor quality on arrival makes the whole production effort meaningless.

Supplying live fish is the surest way to guarantee the consumer receives a genuinely fresh product.

Once confined mainly to ornamental fish and fish seed, live table-fish transport is now gaining importance as consumer lifestyles change.

Frozen fish transport remains especially critical, since quality degradation risk is highest during transit — reinforcing the case for reliable live, oxygenated transport instead.

A dependable onboard oxygen source is becoming a baseline requirement — not an optional upgrade — for live fish logistics operators.

The Problem

Challenges in Current Oxygen Supply Systems

Dependence on Liquid Oxygen

Trucks rely on LOX cylinders, tying operations to a continuous refill supply chain.

High Hidden Costs

Refilling, transport, and safety management of cylinders add significant recurring cost.

Safety Risk

Compressed and liquid oxygen carry real risk of leakage, fire, or explosion.

No Real-Time Visibility

Conventional systems offer no real-time oxygen monitoring or control.

Rising Fish Mortality

Mortality increases on long-distance hauls when oxygen supply is inconsistent.

The Solution

The O2MOS PSA Oxygen Generator

O2MOS is a PSA (Pressure Swing Adsorption) oxygen generator that produces high-purity oxygen for immediate, continuous use — in virtually any environment where oxygen is needed, simply by switching on the power.

The system uses a high-performance adsorbent material with a dense network of micropores, enabling it to selectively adsorb large volumes of nitrogen and extract high-purity oxygen from ordinary compressed air.

Wherever oxygen is needed, high-purity oxygen can be supplied stably — simply by switching the power on.

How It Works

PSA Technology Principle

Continuous PSA Cycle

  • Based on Pressure Swing Adsorption (PSA) technology.
  • Nitrogen is selectively removed using zeolite molecular sieves.
  • Generates high-purity oxygen (90–93%) from compressed air.
  • Enables 24-hour continuous operation in mobile applications.

The result: no cylinders to refill, no liquid oxygen to transport — just a self-contained system that produces oxygen for as long as the vehicle is powered.

Product Line

O2MOS PSA System Overview for Trucks

  • Compact 12V or 24V DC PSA oxygen generator, purpose-built for live fish transport vehicles.
  • Generates 7 LPM or 3 LPM of continuous oxygen at 90% purity.
  • Modular structure: separate compressor unit and PSA bed unit.
  • Integrated driver-side controller with emergency LOX backup system.
  • Enables continuous oxygen supply even while the vehicle is in motion.

All configurations share the same driver-side controller and emergency LOX backup architecture — only flow rate, voltage, and enclosure size change.

System Design

Basic System Configuration

  • Driver-side controller gives real-time visibility into system status while underway.
  • The PSA generator's modular compressor and bed unit mount securely within the truck bed housing.
  • Oxygen is distributed through a flowmeter panel that lets crew fine-tune flow to each individual tank.
  • Air stones diffuse oxygen evenly through each holding tank at low, fish-safe pressure.

Failsafe Design

Emergency Liquid Oxygen Backup System

  • Continuously monitors O₂ outlet pressure and controller power status from the PSA generator.
  • If pressure or power falls out of range, the backup controller automatically opens the LOX supply valve.
  • High-purity liquid oxygen instantly restores flow to the tank distribution manifold through a check valve — no manual intervention required.
  • Ensures an uninterrupted oxygen supply even in the rare event of a PSA fault, protecting live cargo on long-distance hauls.

System components: PSA generator · O₂Call backup controller · dual flowmeter regulators · LOX cylinder bank · check valves throughout.
