359 seul

The DAL 359 can be adapted to optimize the ventilation system to meet the spatial requirments. The large number of winglets have good ventilation and acoustic qualities (shaped in the form of an aircraft wing). They allow installation even in spaces with high ceilings and high refrigeration needs.

An adaptation due to a possible change of air flow is possible through a modification of the opening of winglets. It is possible to change the pulse, the penetration or the thickness of the flow.

The efficiency of air diffusion (Ezof the high induction DAL 359 diffuser reaches 1.0
This factor may formally be regarded for the purposes of calculating the amount of fresh air for a vessel making use of heating through the ceiling more than 15˚F (8˚C) that the room temperature and returns on the ceiling. The standard 129 is allowed the use of Table 6.2 rating: 5 of ANSI / ASHRAE 62.1 .

         Benefits

     

       • Optimal airflow guidance.

       • Rapid reduction in speeds and temperature difference.

       • Low acoustic power for large movements of air.

       • Possibility of changing the air flow.

       • Possibility of varying the speed of the exiting air.

       • Approximately 3 times  more induction than a conventional 4-way diffuser.

       • Approximately 3 times less temperature variation in occupied area than a traditionnal diffuser.

       • Possibility of eliminating external heating sources due to the diffuser‘s heating abilities.

       • Fewer diffusers required.

       • Allows a reduction in the total number of units required to circulate a fixed volume of air.

       • Adaptable to systems requiring constant or variable airflows.
