Model CA80SI - Silica Analyzer Liquiline System



Colorimetric system for the monitoring of boiler feedwater, steam, condensate and ion exchangers. Liquiline System CA80SI provides precise online analysis of silica and helps protect plant equipment from glass-like deposits ensuring optimum performance of turbines and ion exchangers. Its unique combination of peristaltic and high-precision dispenser pumps enables extremely reliable operation and low maintenance. The silica analyzer offers advanced diagnostics and can be easily adapted to your process needs by retrofitting up to 6 channels and connecting up to 4 Memosens sensors.

  • Protection of expensive plant equipment in the power industry: The silica analyzer monitors trace levels of silica in water steam cycles helping to avoid glass-like deposits on the equipment surfaces.

  • Early online detection of critical silica levels ensures efficient power plant performance and optimizes maintenance and blowdown cycles by early counter measures.

  • Standard heteropoly blue method allows direct comparability to lab results.

  • Best reliability: Unique combination of peristaltic and high-precisions dispenser pumps ensures stable operation and low maintenance.

  • Optimized investment: The option of up to 6 sample channels meets changing process needs at any time, and connection of Memosens sensors allows an easy upgrade to a complete measuring station.

  • Seamless integration into process control systems thanks to digital field buses such as Modbus, EtherNet/IP or PROFIBUS.

  • Advanced diagnostics and remote access via web server enable fast remedy in case of errors.
