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 that holds steam boiler water TDS on target by driving a blowdown valve from a conductivity probe signal. It works with CP10 and CP30 conductivity probes, accepts a Pt100 for
The BC3250 is an advanced Spirax Sarco boiler blowdown controller that monitors boiler water TDS conductivity, regulates continuous or pulsed surface blowdown, and incorporates an integrated bottom blowdown timer with 128x64 graph
The Spirax Sarco CP30 is a cut-to-length conductivity probe for steam boiler conductivity or total dissolved solids (TDS) measurement and blowdown monitoring or control, with 300, 500, 1000 and 1500 mm nominal electrode lengths an
BCR3150 is a 24 Vdc conductivity-based TDS blowdown monitor and limiter for boiler-water control and compatible conductive condensate-contamination monitoring systems.
