GESTRA Kalorimat return temperature limiter BW 31 manages industrial heating network consumption based on demand, boosting medium flow in the return line as temperature decreases. Flow discharge occurs only when the medium temperature falls below the set closing point. The BW31A model regulates medium flow via a thermovit regulator and spring pressure, primarily for hot oil applications.
