Spirax bcs 3 automatic blowdown control system offered by forbes marshall blown down boiler only when, and for as long as required thus protecting your boiler and money from being blown down the drain. The bcs3 controller periodically opens the blowdown valve to start a flow of boiler water past the system`s conductivity sensor. The measured value is then compared with the desired tds set point in the controller if the measured value is lower than the set point, the blowdown valve is closed. If it has reached the set point, the blowdown valve remains open until the measured value drops below the set point. The time between blowdown tests is automatically related to your boiler`s steam load by monitoring the boiler firing. The spirax bcs3 controllers incorporate state of the art features to optimise your blowdown cycle, protect your steam system and save you money. With microprocessor based electronics, a 4 digit led continuous display of tds and system status and simple push button interface for easy commissioning, calibration, and operation. Other features include high tds alarm relay output for remote indication, an advanced probe conditioning circuit that automatically descales the conductivity probe and automatic temperature compensation.
