Large Capacity Ozone Generator System

Yes. We manufacture custom capacity ozone generators for any requirement between 2 kg/hr and 150 kg/hr — including non-standard sizes such as 4 kg/hr, 6 kg/hr, 7 kg/hr, 8 kg/hr, 9 kg/hr, 12 kg/hr, 15 kg/hr, 18 kg/hr, 25 kg/hr, 35 kg/hr, 40 kg/hr, 45 kg/hr, 55 kg/hr, 65 kg/hr, 70 kg/hr, 75 kg/hr, 90 kg/hr, 125 kg/hr, and 140 kg/hr.

Dry Air (DA) ozone generators draw ambient air through a built-in desiccant dryer and produce ozone at 22–35 g/Nm³. Available from 2 kg/hr to 60 kg/hr. Pure Oxygen (OX) generators use ≥93% purity oxygen from a VPSA generator or LOX source and produce ozone at 120–148 g/Nm³ — over 4× higher concentration than air feed. OF units consume only 6–8 kWh per kg O₃ vs 14–16 kWh for AF, reducing operating power cost by 50–60%. OF is recommended for continuous 24/7 operation above 2 kg/hr and is the only option available above 60 kg/hr.

Ozone India Technology manufactures pure oxygen (OX) ozone generators up to 150,000 g/hr (150 kg/hr) — model OZUV-150K-OX. For Dry Air (DA) configuration, the maximum single unit is 60,000 g/hr (60 kg/hr — model OZUV-60K-DA). Capacities above 150 kg/hr can be achieved by operating multiple units in parallel with a common manifold. Contact our project team at +91 96500 17943 for requirements above 150 kg/hr.

Required ozone capacity (g/hr) = Flow rate (m³/hr) × Ozone dose (mg/L) ÷ Transfer efficiency. Use transfer efficiency of 0.90 for pure oxygen (OX) with fine bubble diffuser, and 0.85 for air-fed. Standard ozone doses: 1–3 mg/L for municipal drinking water (taste/odour), 2–4 mg/L for Cryptosporidium inactivation (US EPA CT), 5–10 mg/L for STP tertiary polishing, 10–30 mg/L for industrial ETP colour removal, 0.1–0.5 mg/L for pharmaceutical purified water and cooling tower Legionella control.

Yes — mandatory. All contact vessels produce undissolved ozone off-gas from the vent that must pass through a catalytic MnO₂ destructor before reaching the atmosphere or plant room, as required by CE Machinery Directive 2006/42/EC. All Ozone India Technology large capacity systems include an ozone destructor sized at 110% of generator rated output. The destructor reduces off-gas ozone from up to 3,000 ppm inlet to below 0.05 ppm at rated conditions, well below the OSHA PEL of 0.1 ppm.

All Ozone India Technology large capacity systems include a PLC control panel with 7-inch colour HMI touchscreen. SCADA integration is available via Modbus RTU (RS-485), Modbus TCP/IP (Ethernet), Profibus DP, and optionally OPC-UA. The 4–20 mA analog output from the dissolved ozone monitor can be wired directly to the generator modulating input for automatic closed-loop control of dissolved ozone residual. Remote monitoring via GPRS/4G and integration with plant DCS or SCADA is standard for projects above 10 kg/hr.

Standard large capacity generators in the 2–10 kg/hr range are assembled and factory tested within 4–6 weeks of order confirmation and payment. Models from 10–50 kg/hr require 6–10 weeks. Units above 50 kg/hr are custom-engineered with a 10–16 week lead time. Export orders with full CE documentation package (Declaration of Conformity, test reports, Factory Acceptance Test report) add 1–2 weeks. For urgent project requirements, contact our team at +91 96500 17943 — partial deliveries from stock components may be possible in some cases.

All large capacity Ozone India Technology ozone generators require a continuous cooling water supply. Cooling water quality must meet: TDS below 500 ppm, total hardness below 100 ppm as CaCO₃, pH between 7.0 and 8.5, inlet temperature 20–30°C, and no suspended solids or biological contamination. Required flow rates range from 6–8 m³/h (OZUV-2K-DA) up to 255–300 m³/h (OZUV-150K-OX). A dedicated cooling tower or chiller is typically required for units above 10 kg/hr. Soft water or demineralised water must not be used as it causes corrosion.
