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 orifice kit.
• 120 VAC, 50/60 HZ, 15 amp.
• Solid state electronics.
• NEMA 4X enclosure.
