Prominent Ozone System OZONFILT® OZMa

Description

Can’t see what you want?

Ozone capacity 70 – 735 g ozone/h

OZONFILT® OZMa represents maximum operational safety with minimal operating costs. The ozone generator is maintenance-free and generates up to 735 g/h of ozone from compressed air or oxygen.

Powerful and yet environmentally-friendly. Disinfect and oxidise ecologically and economically.

The ozone systems OZONFILT® OZMa have been designed as pressurised systems, in which the operating gas – air or oxygen – is fed into the ozonegenerator under pressure.

Air is used as the operating gas in the ozone system Ozonfilt® OZMaA types 1 to 6

The ozone is generated from the oxygen in the ambient air and simultaneously metered. A demand-led, self-optimising pressure swing dryer reduces the consumption of compressed air to a minimum. Ozone can therefore be generated operationally safely and reliably even with a high level of ambient air humidity with ozone concentrations of up to 20 g/Nm3. Ozoneconcentrations of between 3 and 12 ppm can be achieved in the water to be treated with suitable mixing units, depending on the temperature.

Oxygen is used as the operating gas in the ozonesystem Ozonfilt® OZMaO type 1 to 6

Operation with oxygen permits ozone generation with ozone concentrations of up to 150 g/Nm3. Depending on the system type, ozone is produced in 1-3 generators from oxygen provided from special oxygen generators or bottles. Using the suitable mixing equipment, ozone concentrations of up to 90 ppm can be achieved in the water to be treated, depending on the temperature.

Your benefits

  • Economical: maintenance-free generator concept with virtually unlimited service life
  • Up to 30% energy savings for air treatment, thanks to demand-led and self-optimising air drying compared with conventional air treatment.
  • Automatic control of the operating gas depending on the ozone output, therefore reduced consumption of operating gas produced with intensive use of energy.
  • High ozone concentration ensures optimum ozone solubility in water
  • Direct injection without injector system at up to 2 bar back pressure
  • Automatic ozone generation, virtually independent of fluctuations in main voltage and pressure

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 microcontaminants, reduction of sewage sludge
  • Food and beverage industry: Oxidation of iron and manganese, disinfection of potable water and rinser water
  • Swimming pools: Degradation of disinfection by-products, reliable microbiological barrier and production of crystal-clear water thanks to its microflocculating effect
  • Industry: Legionella prevention and disinfection of cooling water

Technical Details

  • Compact mounting, ready-to-use in a painted steel cabinet or optionally in a stainless steel cabinet
  • With integrated filter package for the removal of dust and small amounts of residual oil in the compressed air
  • Special dielectric with excellent cooling: In spite of the low cooling water consumption, heat is quickly and efficiently discharged before the ozone produced can decompose due to excessive heat.
  • PLC with integrated ozone measurement and PID control
  • 7″ touch panel with data logger and screen recorder
  • Multiple communication interfaces (e.g. LAN, PROFIBUS® DP)
  • Excellent efficiency: Over 90% of the ozone is dissolved in the water, thanks to the special construction of the mixing unit.
  • Integration of a dew point sensor to monitor the quality of compressed air
  • Integration of an air conditioning unit to adjust the temperature of the ozone system
  • Pause input for external switching on/off
  • Contact input for locking the system, for example in the absence of flow
  • Digital input for connection of a gas detector
  • Digital input for control of two power stages
  • 0/4-20 mA input for external output control depending on the flow or measured value with a PIC controller
  • Second freely configurable 0/ 4-20 mA input
  • Contact output for operating status
  • Contact output for collective malfunction alert
  • Contact output for limit value transgression, ozone concentration in the water too low
  • One freely configurable 0/ 4-20 mA output
