The CHC type variable throw slot diffuser is designed for ceiling applications to achieve the different throw characteristics required in heating and cooling of spaces automatically. Since cold air tends to go down, and warm air tends to float; it is necessary that air is supplied horizontally when cooling, and vertically downwards when heating. These diffusers are intended for supply air usage, together with the accessories required for various demands. Using CHA type diffusers as extract units, a visual uniformity is achieved on the ceiling.
Specifications
These diffusers have adjustable blades and have one to four slots. Versatile design provides the option of commanding the blades in the same or opposite directions (if more than one slot). It is also possible to manipulate the number of blades to move in parallel or opposingly. There are blades on both sides of each slot, to direct the outgoing air stream. With diffusers having more than one slot, it is possible to throw the air stream either in the same, or in opposing directions. The motion is given to only one of the blades at the sides of the slots, and the other blade remains pointing downwards. These diffusers are recommended for use with ceiling heights up to 4 m, with a supply temperature difference of -10 / +15ºC. With this thermostatic slot diffuser, when the supply air is cool (<22ºC), the air stream is thrown horizontally; and when it is warm (>29ºC), it is thrown vertically downwards, by the moving of the blades. This movement is performed by a thermostatic element inside the diffuser and no manual or electrical power or adjustments are necessary. The diffusers are made up to 1500 mm max. length in a single unit.
