System Architecture

SPLIT-MODULE DESIGN

A

Separated Compressor & PSA Bed

Unlike integrated units, the O2MOS-7LC physically separates the air compressor from the zeolite adsorption bed. This reduces heat transfer, extends sieve life, and allows independent servicing of each module.

Modular Service Thermal Isolation
B

DC 24V Voltage

Runs directly from vehicle or vessel battery systems. Compatible with standard 24V truck electrics and 24V heavy-duty marine or commercial vehicle systems. No inverter required.

DC 24V 20Ah Rated
C

DC O₂CON Remote Controller

Compact panel-mount controller installed in the driver's cab. Displays real-time O₂ flow rate, output pressure, and DC voltage. Full START / STOP / RESET control without leaving the cab.

Real-Time Monitoring Wired Remote
D

SUS 304 Stainless Steel Cabinet

Marine-grade brushed stainless steel enclosure. Corrosion-resistant, vibration-dampened, and sealed for saltwater spray environments. Far superior to powder-coated steel for marine and fishery applications.

SUS 304 Salt-Spray Resistant
E

Zero Cylinder Dependency

Generates oxygen from atmospheric air. Eliminates high-pressure cylinder logistics, refill schedules, storage requirements, and explosion risks associated with compressed gas cylinders.

No Consumables 24H Auto-Run
Target Applications

WHERE O2MOS-7LC OPERATES

🚚

Live-Fish Transport Trucks

Primary application. Runs on the truck's own 24V battery. Continuous O₂ supply to fish tanks during transit — from loading dock to destination, no port refills needed.

⚡ DC24V
⛵

Small Fishing Vessels

DC power makes it ideal for small vessels without AC generators. Keeps live bait and catch oxygenated throughout extended offshore operations on vessel battery systems.

🔩 SUS Marine Grade
🏭

Aquaculture & Shore Facilities

Land-based hatcheries and fish farms with DC power infrastructure. Cab controller can be remounted as a wall panel for central monitoring of O₂ supply.

Operation Guide

RUN IT IN 3 STEPS

1

Start & Check Status

Press START on the cab controller. The green OPERATE LED lights up and the system starts running.

Each press of SELECT cycles through supply voltage, process pressure, oxygen supply pressure, unit temperature and total running time.

2

Inspect Operation

At the externally installed oxygen generator, check the flow meter and pressure gauge by eye, and listen to the machine:

  • Lower compressor: machine running sound
  • Upper bed: nitrogen exhaust sound (a short “poof”)

Check Alarms & Respond

If the controller raises an alarm, read the alarm message shown on the display.

Respond according to the corrective action for that alarm type.

LED Indicators & Alarms

LINE · PROCESS · OPERATE · POWER

When an alarm sounds

  1. Check the LED and the error code on the display.
  2. Press the RESET button to silence the buzzer.
  3. Respond according to the troubleshooting actions.
POWER
Green LED stays ON whenever power is connected.
OPERATE
Green LED is ON only while the unit is running.

POWER alarm

LOW VOLTAGE
Green LED blinks + buzzer

Low voltage — the supply voltage is below the set threshold.

LINE alarm

P2 ERROR
Red LED blinks + buzzer

Oxygen leak, or pressure below the set threshold.

PROCESS alarm

P1 ERROR
Red LED blinks + buzzer

The oxygen generator is not operating — a fault is expected.
