Greenheck’s new remote balancing dampers are ideal for applications where tight spaces make it difficult to access and manually adjust the damper and balance airflow. Instead of using a traditional mechanical cable, which is prone to binding, Greenheck says its remote balancing dampers use a standard RJ11 cable that is run to a phone jack-style plug. Greenheck’s EZ Balance smart controller can then be plugged into the jack to regulate the damper’s blade position and balance the system. Two models of Greenheck remote balancing dampers can be specified. Model RDB-10 is a single-blade rectangular balancing damper with a 9-volt actuator kit; model RBDR-50 is a round balancing damper with a factory mounted 9-volt actuator. Accessories, including cable and mounting plates, are also available.
