Temperature com-
pensation
Internal temperature compensation 41 to 113°F (5 – 45°C)
Storage temperature 14 to 113°F (-10 – +45 °C) (without electrolyte)
Max. pressure
1.5 bar (21.76 PSI) with suitable flow cell, no pressure surges and/or
vibrations. Observe the back pressure of the flow cell!
Water quality
All types of water, swimming pool,
drinking, service and process
water (limescale deposits can
block the membrane).
All types of water, swimming pool,
drinking, service and process
water (also containing surfac-
tants), (limescale deposits can
block the membrane).
Conductivity > 1 µS/cm to max. 40 mS/cm
Flow 1.6 to 9.2 gal/hr (6 – 35 l/h), as constant as possible
Service life
Service life of the electrolyte in operation approx. 6 months, service
life of the membrane cap typically 1 year (less with poor water qua-
lity, e.g. sand, dirt)
Cross-sensitivity Ozone, peracetic acid Chlorine dioxide, peracetic acid
Selectivity Toward chlorine, bromine, hydrogen peroxide
