lindab | we simplify construction Active chilled beam Plexus Adjustment JetCone Plexus is delivered as standard with Lindab’s JetCone air volume adjustment system. JetCone makes Plexus to a very flexible product with possibility of adjusting air diffusion, air volume and air pressure. Adjustment is made by setting the four adjustment regulators into different positions. The adjustment is done without any tools, which makes it very fast and easy. The fast adjustment system gives an opportu- nity within planning, since the product choice can be made in an early stage and the products can be drawn into the plan- ning of the project even though the planner do not have all the required data. To offer the best flexibility concerning the ventilation air volume, Plexus 60 can be ordered in four different types S/SA (standard), L (low), M (medium) and H (high). The different types results in that Plexus receives different operating ranges for minimum and maximum air volume. By limiting the operating ranges in different configurations, you can with our JetCone adjustment system easily obtain a very accurate adjustment to requested air volume. Type S/SA are Lindab's standard types which have a variable air volume capacity covering the most common demands. In configuration L, M and H we have combined the JetCone system with angled nozzles to be able to offer three prede- fined operating ranges. These operating ranges is overlap- ping each other to be able to give a very accurate regulation. Type L is predefined to the same operating range such as S, while M and H have a operating range which gives higher air volumes. The big advantage is that L, M and H easily can be re-configured and replace each other. The difference between type L, M, H and type S/SA is that type S/SA can handle a higher nozzle pressure with low sound levels and gives a little bit higher capacities at those operating circumstances. Diagram 2 and 3 shows the capac- ity for the different types. Diagram 10, 11 and 12 shows the minimum and maximum air volume, and the sound level at the specific operating point. Plexus 120 is only available in standard type S/SA. Example Today one person is sitting in a cell office. The company is making an expansion and employes one more person, who should be placed in the same room. The air volume then needs to be adjusted to cover the fresh air requirement for two persons instead of one person. The air volume is adjust- ed by modifying the position of the adjustment point and the requested result is given. If it is requested to direct the air diffusion in a certain way this is also possible to do. With the JetCone adjustment system it is possible to get an asym- metric air pattern. Picture 9.Lindab's JetCone system. Optimal Diffusion Pattern As the air is not supplied in parallel rays (stream), but in a sun shaped 360° pattern. The air rays (stream) never collide with the result of longer throws. Plexus has 30% shorter throws than similar products. The significant shorter throw makes it possible to place the units closer together and thereby it is possible to supply much more cooling capacity to the room. Picture 10.With Plexus you create all conditions for lower air velocities in the occupied zone which result in a climate without draughts in the most natural way. Picture 8.
