Rickard electronic ceiling diffusers are available in 3 distinctive styles: Square, Round and Swirl. The Square and Round style diffusers produce low noise levels and are designed for general building zones where uniform radial discharge is the preferred supply air distribution pattern. The Swirl style diffuser is a more efficient solution for generating high induction between supply and room air.

Room temperature is controlled and maintained by varying the supply air volume in accordance with demand. Air volume control is achieved through the vertical up and down movement of the control disc mechanism within the diffuser. This increases or decreases the aperture size which allows more or less air to enter the occupied space. This effectively maintains constant air movement in the room at discharge volumes from 100% down to approximately 10%. An electric actuator drives the position of the control disc in response to a signal received from the temperature sensor.

All electronic ceiling diffusers are available in the industry’s most popular neck sizes; 150, 200, 250 and 300mm diameters. The square and round style diffusers include an additional 350 diameter neck size. There are 2 overall diffuser sizes available. VSD, VCD and VSW models are offered in a 595 x 595mm finished size, while the VRD and VRW come in a 580 diameter size. All electronic ceiling diffusers are available with an in-built occupancy sensor
