The essence of Demand Control Ventilation (DCV) is the effectiveness and efficiency of controlling the fans and other components of a ventilation system, by the ability to control in order to provide variable degrees of ventilation that may be required to handle variable occupancy levels.
This is achieved by using different sensors in order to provide an array of different detection modules which identify the level of spatial contaminant within the building (e.g. people, temperature, CO2, humidity etc). These sensors provide an almost infinite amount of possible variation to the ventilation system provided, so that it matches almost identically, the level of occupation within the area to be ventilated.
Furthermore, the intelligent system will interface easily with other enabling sensors such as Passive Infrared
PIR), Building Management Systems (BMS), Building Automation Systems (BAS), which means the customer can be alerted to changes in performance levels, energy levels or maintenance requirements.
Elta offer both Single and Twin fan ranges available in multiple sizes and motor arrangements, all tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance) at Elta Fans own test facility, meaning accurate, up to date information on performance and noise data that can be relied upon.
