VAV Variable Air Terminal Unit with Conrtol Box SVT-CB Series

SAFID SVT 500 Series

VAV air terminal units are designed to achieve variable air volume supply of conditioned air to a room in single duct air distribution systems. The SVT air terminals are equipped with air flow sensor in the unit’s inlet to allow pressure-independent control of air flow on the basis of a control signal and fitted with Belimo actuator/ controller. The Belimo actuator/controller is linearized with the SVT 500 Series in order to achieve a high standard performance of the VAV air terminals. They have a wide range of sizes with capacities from 150CFM to 7850CFM. The SVT 500 Series will work equally well in Variable Air Volume (VAV) and Constant Air Volume (CAV) systems. The air volume supplied to the room varies in direct response of actuator to signals from the room thermostat to maintain the room designed temperature while the air flow controller maintain the maximum and minimum amount of designed air flows to be supplied to the room. The SVT air terminals are available with a variety of accessories. They can be specified sound attenuators, electric heaters, hot water coils, multiple outlet plenums and other optional accessories. The accessories (except the multiple outlet plenums) are shipped factory attached to SVT air terminals and have a standard slip and drive connection.

SCVT 500 Series: Model SCVT 500 Series are Constant Air Volume Air Terminal Units which has the same construction as SVT 500 Series but the calibration of SCVT 500 Series will be with constant air volume flow.                                                                    

Standard Construction Casing: Air Terminal casing, Inlet & Damper are built of 22 gauge galvanized steel sheet, conform to ASTM A653, LFQ, G90 zinc coating.

Insulation: 25mm thk. Acoustic lining with a strong and dimensionally stable Woven Glass Fiber Fabric (WGF) facing, 48kg/M3 density, complies with the requirements of NFPA 90A.                                                                                                    

Air Flow Sensor: Aluminum multiple averaging flow probe that offers an excellent air flow sensing capability.

Controls: The SVT air terminals can be specified with electric controls.

Standard Controls are Belimo Actuator/controller modulating type. Standard Connections: S-Slip and Drive Slip connection for discharge side.
