The system has a controller sensor that measures the feed water conductivity and temperature. If the conductivity exceeds a predetermined level, the drain valve is opened and the condensate with a high conductivity is discharged and the water returning from the separator or from the system is became discarged. The blowdown valve closes when the conductivity controller drops below the set value.

Advantages

• It helps to provide clean and dry steam.
• Reduces blowdown and water treatment costs.
• Provides accurate conductivity control.
• The coil extends its life.
• Outputs 0.4-20mA for remote monitoring.
• The controller shows the blowdown status.

Blowdown Control System for Steam Generator:
Sensor Chamber: 1 1/4 ” BSP Conductivity sensor, sampling connection
Blow valve: Solenoid valve (up to 15 bar)
Also recommended: Strainer and shut-off valve, sample cooling vessel
