Somerset, England, company DeltaSense has introduced a new, ultrafast damper actuator for critical ventilation applications.
DeltaSense’s new HMO 24 is an ultrafast motorised damper actuator, which has been designed for exhaust systems that demand a rapid response. It can take as little as one second to rotate a full 90 degrees and is suitable for smoke extraction and other critical ventilation applications. Response time is adjustable within the 1 – 10 s range by changing the DIP switch settings. The direction of rotation can be adjusted in the same way.
The HMO 24 can be mounted directly on an 8 mm x 8 mm square shaft, or on a round shaft using an adaptor. Operating from a 24 V ac/dc supply, the unit has built-in overload protection and produces a minimum torque of 3 Nm. It is sealed to IP54 and is suitable only for use with dampers without mechanical stops and flexible rubber seals.
