The KEMA R-BLE24 is a reversible electric actuator for smoke control dampers — the drive unit that opens and closes smoke ventilation valves in building fire safety systems. The actuator delivers 15 Nm torque through a 12 x 12 transmission link with a turning time under 30 seconds, selectable left or right rotation, and two auxiliary switches for position signaling to the fire control panel.
Protection class III with an IP54 enclosure suits installation in ventilation shafts and ceiling spaces. Smoke control is the life-safety layer of building ventilation: in fire, dampers must move reliably to extract smoke from escape routes, so the actuators that drive them are certified, specified-by-project hardware consumed by every significant commercial and residential building.
With a 20-unit minimum order at strong component pricing, the R-BLE24 targets fire safety integrators, ventilation contractors and HVAC equipment distributors equipping smoke extraction projects from Russian production.
