Stamolys CA71SI
Silicate Analyzer
Compact photometric analysis system for the silicate measurement in
ultrapure water and boiler feedwater
TI00364C/07/EN/14.12
71161856
Application
• Ultrapure water
• Boiler feedwater
• Steam and condensate analysis
• Reversed osmosis
• Demineralizers
Industries:
• Pharmaceutical industry
• Power stations
Your benefits
Stamolys CA71SI measures the silicate content quasi-
continuously to assure a constant optimum water quality. This is
of special advantage in the performance monitoring of ion
exchange and reversed osmosis systems. The analyzer replaces
frequent manual sampling and exactly determines the silicate
break through of the system.
• Stainless steel or glass-fibre reinforced carbon housing
available
• Two channel version available
• Measured value storage using integrated data logger
• Automatic calibration and self-cleaning
• Free selectable measuring, cleaning and calibration intervals

Page 2: Function And System Design
The standard limit for boiler feed water is 0.02 ppm silicic acid (SiO ). For injection and boiler water the standard limits are pressure dependent. For example, at an operational pressure of 68 bar (986 psi), the concentration of silicic acid in boiler water must not exceed 10 ppb.
