SENTRY SWAS Steam and Water Analysis System

SWAS is an application-specific engineered sample panel that delivers steam and water samples to analyzers at the right temperature while keeping them representative. The aim is to reliably access real-time data to control and optimize water chemistry. Samples taken from boiler, turbine and condensate lines pass through compatible parts such as a cooler, resin column and temperature control unit.

• Each system is designed separately according to the customer's number of lines, pressure and instrument list.
• Easy access to resin columns shortens filling time.
• Temperature control units bring the sample to 25 °C.
• Retrofit compatible with existing water/steam equipment is possible.
• A special shelter option protects the sample equipment.

The same manufacturer's single-line sample systems, helical coolers, self-filling cation resin columns, thermal shut-off valve and high-pressure reducing valve can be added to the panel.

When selecting sample lines, the pressures and temperatures of boiler, superheated steam and condensate points are assessed separately, and the right cooler type and resin column are determined for each line. Analyzers thus receive only samples conditioned for measurement.

For plant operators, Tetra carries out project engineering from listing sample points to panel layout. After shipment to site, connection, initial commissioning and spare parts tracking for resin and cooler components are handled by the same team.
