Round VAV Terminal Units
SDR
STEKON SDR adjusts the conditioned air volume supplied to the room based on data received from the thermostat or building automation system, ensuring minimal pressure drop and low noise levels. Thanks to the air flow sensor within the unit, it detects instantaneous air changes and positions the damper to allow the desired air volume, independently of pressure.
The VAV Unit provides good air quality by adjusting the air volume based on signals received from local or central systems, according to changing conditions in the serviced environment, such as the number of occupants or cooling requirements, while also preventing excessive ventilation.
The SDR Circular VAV Terminal Unit ensures precise flow rate adjustment by measuring air flow velocity at accurate points across the entire cross-section and averaging these measurements.
