Series KU2 KU5 KU6 KU8The KU2 KU5 KU6 KU8 series diffusers are composed of a fixed external cone and central part composed of individually cones that can be adjusted individually and to a millimetre. The different position of the cones allows to vary the direction of the air flow, so as to obtain horizontal air flows (in cooling) or vertical air flows (in heating). These diffusers are installed at a height ranging from 2,6 to 6 meters in height.The diffuser is fixed laterally using screws to the connection piece of the duct or plenum, alternatively they can be fitter to counter ceilings using clips. The air flow regulation is made by rising or lowering each individual cone.

OVERVIEW

ADJUSTABLE CONES CIRCULAR DIFFUSERS

OVERVIEW: The KU 2-5-6-8 series of diffusers are composed from an external containment cone and by a central adjustable section with cones that may be adjusted individually to the nearest millimetre.The different positioning of the round elements allows to vary the direction of the air to obtain combined or single are flows, both vertically or horizontally. For this reason, this supply air diffuser is ideal in all those applications where it is necessary to heat or cool. In the same way it can be used for the extraction of air from the room. The standard height of installation of the diffuser is between 2.6 and 6 metres.

INSTALLATION : The diffuser is fixed laterally using screws directly to the plenum's connection. Various clips are available to fix the diffuser to plaster board counter ceilings and versions with flat or lowered "fineline" panels for use in modular counter ceilings

ADJUSTABLE CONES CIRCULAR DIFFUSERS KU 5 CT

SERIESVERSION WITH AUTOMATIC REGULATION

WITH THERMOSTATIC SPRING

The KU5 CT diffusers allow to automatically regulate the cones in the summer or winter position without the need of a technician. The work without any auxiliary power (e.g.. electrical power supply) and do not require any maintenance. The movement of the intermediate cones is controlled by means of a special shape remembering spring who's cycle of use determines the position of the cones in relations to the temperature. In this way the flow of air is controlled in relation to the temperature, enabling the intermediate cones to be always in the optimal position, both when in the cooling and heating faze.The memory spring varies its extension within a temperature range of 14°C and 40°C.The minimum lasting time of the spring is 100,000 cycles. A cycle is given from an extension followed by a compression of the spring. If, for example, we consider to be in the position to start the system in the morning and to turn it off in the evening, the spring will last o average about 270 years. The drawings shows the two positions at full extension and full compression of the spring, the 0% position in cooling conditions

SELECTION

SELECTION METHODUsing the diagram shown below it is possible to make a first selection of the diffuser on the basis of the air flow. Saying so, it is advised to verify, using the diagrams of the technical data shown in the following pages, the actual compliance of the choice made with the specific use intended for the diffuser.

CONE REGULATIONThe technical data considers two regulation positions for the diffuser cones, "summer" and "winter".

Summer regulationThe summer regulation corresponds to the lowering of the central cones up to almost 15mm below the actual height of the ceiling.This regulation achieves a fresh air horizontal throw which, supported by the coanda effect flows along the ceiling

supported by the coanda effect, flows along the ceiling, gradually mixing with the air in the room therefore avoiding air currents forming with the occupied area.Winter regulationThe winter regulation corresponds to the lifting of the central cones up to almost 15mm above the actual height of the ceiling. This regulation drives the hot air directly towards the occupied area, avoiding any different air temperature layers from forming.
