Product Description
GESTRA LRR 1-51 Continuous Blowdown Controller
The GESTRA LRR 1-51 is a high-performance continuous blowdown controller designed to automatically monitor and regulate the conductivity of boiler water in steam boiler plants. By continuously measuring the Total Dissolved Solids (TDS) via a connected conductivity electrode (e.g., GESTRA LRG series), the LRR 1-51 precisely controls the blowdown valve. This process ensures optimal boiler operation by preventing scaling, corrosion, and carry-over of solids into the steam system. Its precise control helps to minimize energy and water losses, leading to significant cost savings and improved plant efficiency and safety.
