Damper actuators with electronic emergency functions are designed for extended functionalities in HVAC systems fan coil and laboratory applications. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS).
NECA and NECM series electronic fail-safe damper actuators are designed for extended functionalities in HVAC systems fan coil and laboratory applications. During normal operation, the actuator motorizes the damper. When the power supply is off, the actuator is back to its original position. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS).

MECA series electronic fail-safe damper actuators are designed for extended functionalities in HVAC systems fan coil and laboratory applications. During normal operation, the actuator motorizes the damper. When the power supply is off the actuator is back to its original position. Electronic Return (ER) can manage short voltage interruptions for max. 4 seconds. In case of longer voltage interruption actuator will move the damper or valve to a predefined emergency position (EPS). These actuators have Modbus communication and could be used for BMS systems.
