Wet SWAS Panel
Complete Steam and Water Analysis Systems for power plant cycle chemistry monitoring — sample extraction, conditioning, online analysers, and data logging in a single integrated panel.
Turnkey Cycle Chemistry Monitoring
Labtech Electronics designs and manufactures complete Wet SWAS (Steam and Water Analysis System) panels for power plant cycle chemistry monitoring. Our systems ensure continuous, accurate measurement of critical water and steam quality parameters — protecting turbines, boilers, and heat exchangers from corrosion and scaling.
System Components
Every Labtech Wet SWAS panel is engineered as a complete, integrated system — from sample extraction to data output.
Sample Extraction Probe
High-temperature, high-pressure sample extraction probes designed for steam and water lines. Constructed from SS316L with isolation valves and pressure-reducing assemblies for safe, representative sampling.
Sample Conditioning Panel
Integrated sample conditioning unit with coolers, pressure regulators, flow controllers, and filtration to deliver conditioned samples at the correct temperature, pressure, and flow rate to each analyser.
pH Analyser
Online pH measurement with high-purity, low-conductivity electrode systems calibrated for boiler feedwater and condensate. Provides continuous pH monitoring to prevent acid or caustic corrosion.
Conductivity Analyser
Cation and specific conductivity analysers for detecting ionic contamination in steam and water. Dual-cell measurement with automatic temperature compensation for accurate, drift-free readings.
Dissolved Oxygen Analyser
Membrane-based or optical dissolved oxygen sensors for ppb-level measurement in boiler feedwater and condensate — critical for preventing oxygen pitting corrosion in boiler tubes.
Silica Analyser
Colorimetric online silica analysers for continuous monitoring of silica carryover in steam — preventing turbine blade deposits and maintaining steam purity within OEM-specified limits.
Sodium Analyser
Ion-selective electrode-based sodium analysers for detecting sodium contamination in steam and condensate — an early indicator of condenser tube leakage and demineraliser breakthrough.
Data Acquisition & Logging
Integrated data acquisition system with local HMI display, trend logging, alarm management, and historical data storage. Generates compliance reports and supports remote access via Ethernet.
SCADA / DCS Integration
Seamless integration with plant SCADA and DCS via Modbus RTU/TCP, HART, or 4–20 mA outputs. All analyser data and alarms are available at the plant control room in real time.
