• Ions exchangers (R2, U2)
R2 ION EXCHANGER
COLUMN FOR LABORATORY USE
Ion exchanger used to produce very pure demineralised water. The column is made up of mixed bed gel-resins for anionic and cationic deionisation.
It removes all the ionised bodies (anions and cations), including silica and CO2.
Conductivity : 0,3 to 2 µS/cm.
Flow : 20 liters/hour
Pressure : 2,5 bar (at ambient temperature)
pH (at 20°C) : 5,5 à 7
Maximum temperature of using : 60°C.
Saturation : after exchange of 715 Meq (1 Meq = 5°F).
Resin goes from Blue to Ochre when it is saturated.

U2 ION EXCHANGER
COLUMN FOR GENERAL USE
Ion exchanger (anions and cations) characterised by a high exchange capacity, the U2 column is intended for producing demineralised water. The anion exchanger has a sufficiently high basicity to fix a large part of the influent CO2.
Conductivity : 3,5 to 10 µS/cm.
Flow : 20 liters/hour
pH (at 20°C) : 5,5 à 7
Pressure : 2,5 bar (at ambient temperature)
Maximum temperature of using : 70°C.
Saturation : after exchange of 893 Meq (1 Meq = 5°F).
Resin goes from Green to Purple when it is saturated.
