Field of application
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.
The CA80SI silica analyzer monitors trace levels of silica in the power industry and utilities:
- Indication of the purity of boiler feed water and steam 
- Provision of early warning for condenser leaks 
- Early warning of exhaustion of ion exchangers 
Benefits
- 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.
