The GESTRA LRR 1-8 a is a digital blowdown controller designed for the precise monitoring and control of boiler water conductivity. It continuously measures the TDS (Total Dissolved Solids) level in ppm and automatically initiates a bottom blowdown when the pre-set limit value is exceeded. This process helps to prevent the formation of scale and deposits, ensuring safe and efficient boiler operation while minimizing energy and water loss. Featuring a clear digital display, easy setpoint (SP) adjustment, and calibration (Cal) functions, the LRR 1-8 a provides reliable, automated control to maintain optimal water quality and protect your steam boiler system.
