RO controller OS3030

RO controller for reverse osmosis plants with conductivity meter

ro controller OS3030 with conductivity meter for water treatment systems


The OS3030 (wall-mounted) ro controller is used for the fully automatic monitoring and control of water treatment plants, which operate on the basis of the process of reverse osmosis. The unit type OS3030 is universal applicable for automatic monitoring and control of reverse osmosis plants. Thia ro controller is equipped with an conductivity meter without temperature meter. There are six possible stages : "Stand by", "Production", "Rinse after production", "Rinse during standby", "Rinse during production" and "Maintenance". Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.


  • User operated programming using double row of illuminated LCD display
  • Display text in English, French, German, Italian, Spanish, Czech or Dutch
  • Simple control utilizing easy to follow symbols
  • Built-in audio signal for 12 programmable signal indicators
  • Adaption to user specific requirements by means of options programmable on site
  • Simple operation by means of a few clear operating symbols
  • Can be used for various sizes of plant
  • 10 programmable stages with several steps in some cases: production, stand-by, rinse after production, rinse during extraction, rinse during stand-by, stop when producing, stop when rising, stop when breakdown, maintenance and stop for maintenance
  • Desalinated water production controlled manually or using level switch
  • Locking of maintenance setting and programming possible by use of code number
  • Input of service telephone number
