Detail
The VIRA BS4 Automatic TDS Blowdown System is designed for stable steam boiler systems where conductivity is used to control surface blowdown. It monitors boiler-water conductivity and operates the blowdown valve when the measured value exceeds the configured set point.
Controlled Boiler-Water Conductivity
Automatic TDS blowdown helps maintain boiler-water quality by removing a controlled quantity of water when conductivity rises above the required level. This supports efficient steam production and helps reduce unnecessary water, heat and water-treatment chemical losses.
System Components
The BS4 system includes a BK 5000-T conductivity controller, a BD 5400 conductivity probe, a DG 5400 probe body and a BKV 5400 blowdown control valve. The controller displays conductivity and TDS values, supports set-point configuration and provides valve-control and alarm functions.
For Stable Boiler Operating Conditions
The BS4 system is suitable for applications with stable operating temperature and pressure. It measures conductivity without automatic temperature compensation. For boiler systems with variable temperature or pressure, consider the VIRA BS4-T temperature-compensated TDS blowdown system.
Application Benefits
- Automatic control of boiler-water conductivity
- Controlled surface blowdown based on the configured set point
- Clear display of conductivity and TDS values
- Support for more consistent boiler-water quality
- Reduced unnecessary losses of water, heat and treatment chemicals
