Conductivity Controller
Surface Blowdown Solid State
Intermittent Sampling
• Controls boiler total dissolved solids (TDS) using
conductivity measurement and automatic surface
blowdown via intermittent sampling.
• Adjustable interval timer (1/4 – 3 hours)
periodically opens an electric valve to sample
boiler water conductivity.
• If the sample is below the micromhos set point
on the potentiometer, blowdown is not required
and the valve will close. If the sample is above
the micromhos set point on the potentiometer,
blowdown is required, and the valve will
remain open.
• Adjustable sample duration timer (10 – 12 minutes)
again samples to determine if sample is below the
micromhos set point on the potentiometer to
permit the valve to close.
• Complete system includes: enclosure, potentiometer,
two timers and LED lights.
• Valve assemblies purchased separately include:
solenoid or motor-operated factory-piped valve
with probe, tee assembly and orice kit.
• 120 VAC, 50/60 HZ, 15 amp.
• Solid state electronics.
• NEMA 4X enclosure.
