Spécifications
Long-reach nozzles are end parts of air handling, air conditioning or heating systems. Nozzles are designed to supply air to the occupied zone for long distance. The temperature difference between the supplied air and the air in the room deflected air stream. This stream could be deflected by internal environment in the room. In heating, ventilation and cooling modes supplied air stream direction has to changed according optimal air distribution requirements in the occupied area. Nozzles could be adjusted manually or by using of actuating mechanism. Fixed nozzles are also manufactured. In this case air stream direction cannot be changed. Adjustable nozzles DDM II/N consist of spherical discharge nozzle placed in the nozzle body and a cylindrical protective ring which cover mounting holes. Adjustable nozzles DDM II/S are equipped by actuating mechanism. For DDM II/N air stream direction can be changed in all directions. For DDM II/S air stream direction can be changed only in one axis. Temperature in the place of installation is permitted to range from -20°C to +70°C. If electrical components are used the temperature range is limited by these components. Nozzles are designed for macroclimatic areas with mild climate according to EN 60 721-3-3. Nozzles are suitable for systems without abrasive, chemical and adhesive particles.
