Limit switches - Import export

The fire dampers are manufactured in the following nominal sizes DN100, DN125, DN160, DN200. The fire dampers are equipped with a thermal fuse mechanism ensuring the damper switch to the safe position in case of reaching an ambient temperature equal to or higher than 72°C. The fire dampers allow using limit switches signalling closed position of the damper blade (1 limit switch) or blades (in case of using 2 limit switches). The casing is made from galvanised steel sheet; the fire damper blade is made from a silicate cement board.

The FDABURML coupling module is a combination of an air valve and a fire damper, coupled with a single housing. This is an alternative to typeical fire valves. The main advantages of the FDABURML are better fire rating and a smaller size with more product configurations and application options. The main component of the coupling module is the CFDM fire damper. The fire damper is available in Ø 100, 125, 160, and 200 mm. The wing blade of the damper provides a very low resistance to the air flow. The fire damper can be ordered with one or two optional limit switches to feed back the actual blade position. The FDABURML coupling modules match the most popular versions of air supply or exhaust valves which can be replaced with one another, even with the coupling module installed in a partition or already in use. The entire coupling module is compact. As a result, the air valves with the mounting frames cannot exceed 50 mm in height.

People's platforms are designed to enable safe boarding or alighting on or off the conveyor belt while transporting people by belt conveyors. The platforms are adapted to be installed on belt conveyors of any parameters. Additionally, with the platforms, a structure is used to install limit switches, sensors and elements of electrical equipment necessary to maintain safety.
