The demineralizer RO 1000 EL  is designed to produce de-ionized water with a very high level of purity for technical uses. The costs of producing the de-ionized water are reduced by up to 50% compared to the normal resin de-ionizers, thanks to the use of reverse osmosis membranes with a high saline rejection, with an over-pressure pump (operating pressure 11-12 bar). All the equipment is mounted on stainless steel (INOX) frames. The water obtained is considered to be of excellent quality, not only with regard to salinity but also with regard to the organic aspect (average elimination 97/98%).

RO 1000 EL is commanded by an electronic panel built with PLC technology interfacing with the PC, capable of directly piloting all the functions of the apparatus: over-pressure pump, solenoid valve, alarm and machine stopping for minimum mains pressure, on-line detection of of the conductivity of the water produced, water quality alarm, possibility of manual functioning or else control of the level in the collecting reservoir by means of 2 floats (minimum and maximum level),o r, lastly, dosing by volume. All the functions of the PLC control panel are protected at inlets and outlets.
The working conditions (flows, pressures) are easily monitored thanks to the three (3) flowmeters (feed water, permeated water, recirculation) and two (2) manometers in glycerine baths (mains pressure and working pressure). 

Finally, RO 1000 EL can be adapted to the user’s purity requirements , since there are 3 versions with different degrees of purity in addition to the possibility of regulating the conductivity of the effluent water at will. 

The electrical control panel is made with IP 65 containers, is completely managed by the PLC interfacing with the PC, both with regard to programming and to auto-diagnosis of the operative stages. In addition there is a conductivity meter with digital reading and functioning, to 2 decimal places, for on-line reading of the quality of the water produced

A visible signal shows the alarm for the quality of the water and consequently the need to change the resins (in the demi and dem i 2 versions) or that the membrane is exhausted (in the basic version).

Working features of the panel.

- Electrical power feed on request : 380 V AC
- Filters on the inlets to avoid malfunctioning caused by
  noise
- Direct command of the inlets: 2 floats (min and max),
  manual starting, and stopping for low pressure
- Direct command of the working elements: inlet solenoid
  valve, over pressure pump and programmable system
  for flushing membrane 
- Protection of the programme through password
- Display of messages and data on the LCD screen
- Clock/calender with command setting daylight saving
  time 
- Programme Timing function to be set by PC (optional)
