HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY OVERVIEW CHARACTERISTICS APPLICATIONS OVERVIEW : APPLICATIONS : The high induction diffusers with variable geometry series KZ The diffuser is designed for civil and industrial applications are a new type °f air ternmd devices. Their unique regulation with any type of mixing ventilation plant and should be system is suitable for heating and cooling applications. Indeed installed at heights between 3 and 25 meters. The high the throw optim^tkrn can be optained by Ae ^juMram of induction diffuser with variable geometry, which can be finning inclination. The finning regulation can be controlled by servomotor changed during operation, can set flows between 200 and 12.000 m3/h with variable temperature gradients ranging from This characteristic together with the good inductive power 30 d 11 °c and the variety of model enables the diffuser to be used in ventilation system for installation height from 3 to 25 meters, SELECTION PROGRAM: with temperature variation from supplied air and ambient from -12° to +30°C (depend on the model, air flow and temperature MP3 has at its disposal a selection program to identify the most vnri/irinn i t 1 o / ideal product, the best regulation, the number and layout of Within this range, KZ diffusers ensure the correct air speed in the occupied area, thus maintaining a steady temperature and diffusers on the basis of the room characteristics and the heat preventing any irregular unwanted air currents. values required. Any problems installing the diffusers in false ceiling are solved For this selection it is possible to contact the Sales Department. by the models fitted with a 595x595 panel. The multilingual program, is usable in the customer area of the company website www.mp3-italia.it. The required password must be requested from the Sales CHARACTERISTICS AND OPERATION : Department. KZ series ceiling diffusers are equipped with 6 pivoting fins, which enable high induction. In this way, the delivery speed and temperature gradient are quickly reduced to the optimum values for the occupied area. The 6 deflector fins employ a variable horizontal part to subdivide the air flow into radial jets, which are forced to swirl around the main axis. The KZ diffusers are suitable to application on rooms with high ceiling. Furhtermore the finning configuration can be regulated in 4 ways (depending on the KZ model): • manual for each fin during installation • manual with a mechanism that controls all fins simultaneously • automatic by on-off actuator kind • automatic by proportional actuator kind Standard the motor externally , upon request the diffuser can be supplied with motor mounted internally.

HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY INSTALLATION EXAMPLE INSTALLATION INSTRUCTIONS: The diffuser is installed directly in both the channel (side or inferior) and the plenum, as illustrated below. The diffuser is fitted directly onto the channel or the plenum itself with screws at the side. The 595x595 integrated panel is installed as a standard false ceiling panel would be. Figure no.3 Fastening to plenum (diffuser with panel) Figure no.6 Fastening to channel with circular coupling Figure no.5 Fastening to channel with circular coupling Figure no.4 Fastening to plenum (diffuser standard)...

HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY OPERATIONS OPERATIONS: Depending on the installation angle, different types of airflow are given off. When the fixture is fitted into the ceiling and with the blades at an angle of more than 50°, there is coanda effect, in this case the launch is increased by approx. 40%. For cooling, the neck speed must not be less than the speeds given in the table below: Blade angle: 67° Immission angle : 150° Radial launch Blade angle: 45° Immission angle: 95° Radial/axial launch Blade angle: 30° Immission angle: 50° Axial launch Blade angle: 15° Immission angle:...

HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY WITH AUTOMATIC REGULATION WITH THERMOSTATIC SPRING OVERVIEW : The KZ-CT series of high induction diffusers use a thermostatic spring with form memory mechanism for the simultaneous inclination of the blades. this systems allows to better obtain an optimum air flow direction in relation to the temperature, in an automatic way. The injected air temperature, in fact, determines the dilation or contraction of the thermostatic spring, which in turn determines the simultaneous rotation of the distribution blades reaching the ideal angel on inclination....

HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY WITH AUTOMATIC REGULATION WITH THERMOSTATIC SPRING WORKING PRINCIPLE : The angle of the blades is adjusted by rotating the central axis of the diffuser, connected to the adjustable blades with the use of cone shaped grooved wheels. The central axis of the diffuser is connected to two springs, of which one is in thermo sensitive material and the another in steel. T he thermo sensitive spring varies its ow n elasticity in relation of the injected air temperature, where as the steel spring maintains constant its own characteristics. The balance between...

HIGH INDUCTION DIFFUSERS WITH VARIABLE GEOMETRY PERFORMANCE The performances here shown allow for a maximum sizing. MP3 has at its disposal a selection program to identify the most ideal product, the best regulation, the number and layout of diffusers on the basis of the room characteristics and the heat values required.
