cold airwarm air Jet nozzles are used for preference where the supply air from thediffuser has to travel a large distance to the occupied zone.This is the case in large rooms (halls, assembly rooms etc.),particularly when the distribution of air via ceiling diffusers is not possible or not practical. Here jet diffusers are arranged in the side wall areas. When the temperature difference between the supply air and the room air changes, the supply air stream is deflected upwards (warm air) or downwards (cold air). The direction of the supply air flow is also affected by other influences such as local convection effects or draughts withinthe room.The direction of the air stream from the type DUK-V jet nozzlecan be easily adjusted manually to suit particular on site conditions. Also the pivoting movement can be motorised within the rangeof ±30°.The electric actuators for this can be externally or internallymounted.The well-designed, aerodynamically efficient shape of Trox jetnozzles results in low noise characteristics. For this reason, and because of the sophisticated design, they can be used in critical areas such as concert halls, theatres, museums etc.The wide range of designs available, the flexibility in adapting to local conditions and compliance with low noise requirementsmean that Trox jet nozzles can be used in almost any airconditioning system. 2
