OSMO-DEM Pure Water Producers

 
The Osmo-dem water purifier series represents the simplest and most immediate system for producing demineralized water with very low conductivity.

The Osmo-dem series models include:

• pre-filtration
• reverse osmosis filtration
• ion-exchange mixed resin demineralization cartridge
• They are equipped with an 10-liter pressurized tank (larger capacities are available upon request).

The water exiting the mixed resin cartridge has an average conductivity of 0.5 μs/cm.

Osmo-dems are ideal for scientific applications (laboratory tests, etc.) and offer the option of drawing demineralized water with low conductivity.


FEATURES

The Osmo-dem St is available in different versions depending on the amount of water demineralized per hour.

The Osmo-dem structure is designed for both freestanding and wall-mounted use, and features front access to the pre-filtration cartridge and reverse osmosis membranes.

Standard equipment: 10 litre pure water tank

Models with higher hourly production capacity are available upon request.

Dimensions: WxHxD 55x127x38 cm


CONSTRUCTION FEATURES
Skid Elegant casing in satin stainless steel (aisi304) on a sturdy stainless steel tubular base (aisi 304)
Dechlorination Activated carbon cartridge containing about 3.5 liters of activated carbon
Micrometric filtration 5 micron filter cartridge
Input Solenoid valve and safety pressure switch against dry running
Pressurization Positive displacement pump with single-phase motor
Membrane Polyamide-wrapped spiral membranes
Diameter 2.5", average salt rejection 99.5%
Pressure vessels stainless steel
Final demineralization Cartridge DF0404 containing lt. 4 of Cationic-Anionic resin suitably mixed
Accumulation By means of a pressurized tank type POLI-15 in polypropylene, total volume lt. 15, volume about 10 liters, automatic system for starting/stopping the osmosis unit according to the volume of water contained in the tank
Pressure indicators n° 3 glycerine bath pressure gauges to display:
- Inlet pressure (from the mains)
- Pump pressure (i.e., reverse osmosis membrane pressure)
- Storage pressure (in the collection tank)
Flow rate indicators n° 1 flowmeter (asameter) for permeate outlet flow control
Conductivity control Digital electronic conductivity meter with double probe to check osmosis water and water at the outlet of the DF 04 mixed resin cartridge
Function control Electrical panel in ABS box containing electronic control boards with conductivity meter

DIMENSIONAL PARAMETERS


Optional accessories

- Additional or alternative tanks of equal or greater capacity are available (nominal capacity 10, 25, or 50 liters).
- Ultraviolet sterilizer with a flow rate of 300 liters/h installed at the outlet of the mixed resin cartridge.
