Spirax Sarco boiler TDS blowdown controls monitor dissolved solids and regulate blowdown to protect steam quality and reduce water and energy loss.
Automatic TDS management depends on both measurement and downstream handling. Pair the controller package with conductivity meters when the measurement scope is widening, and use blowdown vessels when the discharged hot water must be handled more safely.
If the project also wants to reclaim energy from the controlled blowdown stream, continue into boiler blowdown heat recovery systems.
The BC3150 is a Spirax Sarco boiler blowdown controller for steam boilers. It uses conductivity probe input to control the blowdown valve and supports Pt100 temperature compensation, 4-20 mA output, infrared communication and puls
The BC3250 is a Spirax Sarco boiler blowdown controller for steam boilers that monitors boiler water TDS and drives blowdown action automatically while also handling bottom blowdown timing, retransmission, trend display and Modbus
The CP30 is a Spirax Sarco conductivity probe for steam boiler TDS monitoring and blowdown control systems. The probe can be cut to the required insertion length and installed in a probe elbow, threaded flange or boiler connection
BCR3150 is a 24 Vdc conductivity-based TDS blowdown monitor and limiter for boiler-water control and compatible conductive condensate-contamination monitoring systems.
