Model CA80SI - Silica Analyzer Liquiline System

From

0

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.
