What makes a generator 'industrial'?
The difference between a commercial and an industrial ozone generator is not just capacity — it's reliability, redundancy and total cost of ownership. Industrial generators run continuously for years between major services, often unattended. They need: high-purity oxygen feed (≥93% from PSA or liquid O₂); high ozone concentration (≥12 wt%) to minimise off-gas and contactor size; precision frequency-controlled power supplies for stable output; closed-loop cooling with chiller redundancy; multi-zone safety detection; ozone destruct sized to handle worst-case off-gas; and full PLC/SCADA integration with the plant's wider control system. Our industrial generators are built to these standards as a baseline, not as upgrade options.
Applications for industrial-scale ozone
Industrial ozone generators serve markets where chemical-free, residue-free disinfection is non-negotiable. Municipal drinking water is the classic application — councils across New Zealand use ozone to inactivate Cryptosporidium and Giardia (which chlorine cannot reliably kill), oxidise manganese and iron, remove taste-and-odour compounds, and reduce disinfection by-product formation downstream. Major bottled-water producers rely on industrial ozone for guaranteed microbial control and bromate-managed bottling. Industrial wastewater treatment uses ozone for tertiary disinfection, BOD/COD reduction, colour removal and refractory organics oxidation. Large RAS aquaculture systems use high-capacity ozone for pathogen control across multi-tank, multi-tonne fish operations. Industrial cooling towers and process loops use ozone to eliminate biofilm and Legionella risk without the corrosion and discharge issues of chlorine.
Design considerations for large systems
Large ozone systems are not just bigger small systems — they bring engineering challenges that demand specialist expertise. CT-value calculations (concentration × contact time) must be done rigorously for regulatory acceptance. Contactor design is critical: bubble-diffuser, side-stream injection, or U-tube depending on flow, concentration and head. Oxygen feed must be sized correctly — typically PSA on-site generation rather than bottled gas. Heat removal becomes significant at high outputs — industrial generators routinely dissipate tens of kilowatts and require dedicated chilled-water loops. Off-gas destruct must be thermally or catalytically rated for the worst-case ozone concentration leaving the contactor. Safety detection coverage of all ozone-wetted spaces is mandatory. Our engineering team handles every one of these elements as a single integrated package.
Compliance, documentation and council acceptance
Industrial installations — especially municipal drinking water — require comprehensive documentation. Our standard project package includes: process flow diagram, P&IDs to ISA-5.1, CT-value design report, hazard and operability (HAZOP) study, instrument list, valve schedule, electrical schematics, control philosophy, factory acceptance test (FAT) report, site acceptance test (SAT) report, operator training records and full O&M manual with parts list. For drinking water installations we work directly with the water-supply assessor and Taumata Arowai compliance pathway. For food and beverage installations we provide HACCP-aligned validation, including microbial challenge testing where required. Every system is delivered with everything needed for handover and audit.
Long-term partnership, not a one-off sale
Industrial ozone systems run for 20+ years. The supplier you choose isn't a one-off purchase — they're a long-term partner. We've supported some of our installations continuously for over two decades, with successive generations of engineers familiar with the original design. We hold OEM-level spares for every generator we have ever shipped. We maintain digital records of every PLC program, instrument calibration and dielectric replacement. We offer life-extension upgrades (e.g. swapping older transformer-based power supplies for modern inverter drives) without replacing the whole plant. When you buy an industrial ozone generator from us, you buy decades of follow-through.
