The fire dampers mcr WIP/S with thermal trip are designed for embedding in general ventilation systems, in a place where these systems pass through building partitions which separate fire zones. During fire, these fire dampers unable the transfer of smoke and heat using air conditioning and ventilation ducts. During normal operation, the fire damper blades are in the open position. In the case of fire, dampers close automatically or after ignition of thermal release mechanism.The fire dampers mcr WIP/V do not have thermal trips and are used in fire ventilation installations for smoke exhaustion as well as in fire ventilation installations for fresh air inlet providing constantly fresh air for smoke exhaustion purposes. During normal operation, the fire damper blades are in the closed position. In case of fire, dampers automatically open and, depending on type of installation, enable exhausting and transferring smoke and hot gases through the damper or transferring fresh air for smoke exhaustion purposes.
