Redox MiniMAX Ozone Generator | BTAqua
Redox MiniMAX Ozone Generator | BTAqua
Redox Mini
Reliable ozone generation for small tanks, built to aquaculture operational standards. Built-in air pump, air dryer, and dual fan cooling ā plug and play apart from your ORP controller.
The Difference
Most ozone setups require you to buy three separate components and hope they work together. The Redox Minimax is the only hobbyist-grade unit built on aquaculture engineering ā everything you need in one box.
Built-In Air Pump
Delivers ozone under positive pressure ā essential for reactors and protein skimmers. No external pump needed. A skimmer's air draw far exceeds the generator's requirement; the built-in pump handles it.
Integrated Air Dryer
Pre-filled with colour-changing desiccant media. Removes moisture from intake air before it reaches the corona cell ā the single biggest cause of premature ozone generator failure. Replace when the colour changes.
Dual Fan Cooling
Active cooling keeps the corona discharge cell at optimal operating temperature. No overheating, consistent output, longer cell life ā even in warm environments.
Key Features
Variable Output 0ā100%
Fine-tune ozone delivery from zero to full output. Dial it back for sensitive species or small volumes; run full power for heavy bio-loads. Suits all small tank applications.
PLC Circuit Board
Programmable Logic Controller delivers precise, stable output. No flickering, no surges ā just clean, consistent ozone production from a proper control system.
Corona Discharge Technology
The industry-standard method for reliable ozone generation. Produces high-concentration ozone (15ā25 mg/L) from ambient air with consistent, repeatable output.
ABS Construction
Durable, corrosion-resistant housing built for the saltwater environment. Lightweight at under 2 kg, compact enough to sit alongside your skimmer or reactor.
Dual Voltage 110V / 220V
Ships ready for any mains supply worldwide. No voltage selector switch to fumble with ā auto-sensing input handles it.
Oxygen Compatible
Running on bottled oxygen? Simply bypass the air dryer and air pump and feed oxygen straight in. Or keep the dryer as a second line of defence and just bypass the pump. Your call.
Quick Setup Guide
The Redox Minimax is plug and play. All you need is an ORP controller with an internal relay ā and your choice of controller will work.
Connect Power
Plug into mains power (110V or 220V auto-sensing). Position the unit alongside your skimmer or reactor with adequate airflow around the dual cooling fans.
Set Output
Use the output dial to adjust from 0ā100%. Start low for small tanks and sensitive species. Increase as needed based on ORP readings.
Connect ORP Controller
Plug the Redox Minimax into your ORP controller's relay output. The controller will switch the unit on/off to maintain your target ORP setpoint automatically.
Maintain Dryer
Watch the colour-changing desiccant in the dryer tube. When the colour shifts, replace the media. This keeps moisture out of the corona cell and extends generator life.

Both models share the same compact housing. Choose the 1G for smaller bio-loads; step up to the 2G when you need headroom or are running multiple treatment points.
