An automatic blowdown control system optimizes surface blowdown rates by regulating the volume of water discharged from the boiler in relation to the concentration of dissolved solids present.
Automatic boiler blowdown control system.
The model 61 boiler blowdown control system is a rack mount plug and play system which is easy to set up simple to operate and provides cost savings over.

An electronic unit and timer controls the ball valve and boiler.
The bdvs require a downstream isolation valve with a bleed between the two.
Automatic surface blowdown control systems maintain water chemistry within acceptable limits while minimizing blowdown and reducing energy losses.
In the case of remedial work once the pressure has been relieved the downstream isolation valve will be closed.
An automatic blowdown system may be installed on any steam boiler regardless of size or operating duty cycle.
The basic components of an automatic blowdown control system include a measurement assembly a control center and a modulating blowdown control valve.
An automatic blowdown control system continuously monitors the boiler water adjusts the rate of blowdown and maintains the specific conductance of the boiler water at the desired level.
The system can be overridden manually anytime.
Automatic surface blowdown control systems maintain water chemistry within acceptable limits while minimizing blowdown and reducing energy losses.
Blowdown valves bdvs are used to depressurize a system or component in order to carry out maintenance work or if there is an emergency.
