Ozone capacity 10 – 70 g ozone/h

OZONFILT® OZVb is powerful and compact and is ideal for efficient ozone generation from compressed air in the output range of up to 70 g/h. The turnkey ozone system including mixing equipment offers everything you need for safe and seamless operation.

Powerful and environmentally-friendly disinfection and oxidation

Ozone systems OZONFILT® OZVb are pressurised systems in which compressed air is fed into the ozone generator.

Ozone is generated from the oxygen content of the surrounding air, via a compressor and is inducted into the process based on demand. Ozone can now be generated in values of up to 20 g/Nm3, safely and reliably in the many demanding environments and plant room locations globally. Ozoneconcentrations within the water to be treated with values of between 3 and 12 ppm can be achieved using our coordinated mixing equipment with an efficiency of up to 95%.

Your benefits

  • Safe and seamless operation through continuous monitoring of all relevant operating data
  • Simple, safe and reliable operation with process visualisation, thanks to large, colour and clear 4.3" touch panel
  • Compact system with integral air treatment
  • Turnkey complete system with perfectly coordinated mixing device including back pressure valve, vacuum breaker and static mixer
  • Direct injection without injector system for up to 4 bar back pressure
  • Low maintenance and operating costs, thanks to maintenance-free generator concept and virtually infinite service life

Field of application

  • Potable water supply: Oxidation of iron, manganese and arsenic, refinement and taste enhancement and disinfection
  • Waste water treatment: Degradation / reduction of COD and micro-contaminants, reduction of sewage sludge
  • Food and beverage industry: Oxidation of iron and manganese, disinfection of table water and rinser water
  • Swimming pools: Degradation of disinfection by-products, reliable microbiological barrier and production of crystal-clear water, thanks to its micro-flocculating effect
  • Industry: Legionella prevention and disinfection of cooling water

Technical Details

  • 4 different sizes depending on the capacity range
  • Compact mounting in a painted steel cabinet
  • Special dielectric with outstanding cooling performance: in spite of the low cooling water consumption, heat is quickly and efficiently discharged before the ozone produced can decompose due to excessive heat
  • Integrated air treatment based on a pressure swing dryer with adjustable throttle valve and analogue flow measurement and pressure monitoring
  • Continuous analogue pressure measurement in the ozone generator with automatic capacity adjustment to compensate for pressure fluctuations
  • Cooling water system with automatic shut-off valve, adjustment valve and monitoring device via flow and temperature sensor
  • Gas-tight diaphragm valve at the ozone outlet
  • PLC (Programmable Logic Controller) control with operating data recorded on an SD card
  • Simple, safe and reliable operation with process visualisation, thanks to large, colour and clear 4.3" touch panel
  • Contact inputs for external On/Off switching, gas detector connector, external fault alert, flow control
  • Analogue input 4-20 mA for power control depending on the measured value combined with external measuring and control technology
  • Contact outputs for collective malfunction alert, warning and operation
  • Wide range of communication interfaces for connection to higher-level controls or for remote monitoring (LAN web server, PROFIBUS® DP, PROFINET®, Modbus TCP or RTU)
  • Evaluation and analysis program for the simple and fast visualisation of operating data on a PC


  • Stainless steel control cabinet
  • Pressure controller with filter unit at the compressed air input
  • Different designs of ready-wired installed mixing unit up to complete equipment including back pressure valve, vacuum breaker and integral static mixer
  • Air conditioning: The system can be equipped with integral air conditioning with ambient temperatures above 40 °C
  • Control of a cooling water heat exchanger
  • Integration of a dew point sensor to monitor the quality of compressed air
