Features and Benefits
All models are designed for direct connection to standard diameter flexible or rigid circular ducting with long spigots. Spigot is on the underside of the unit so can be fitted directly to the main duct.
Integrated commissioning control allows single speed selection and also limits maximum speed if used with an external potentiometer.
External roof mounting outside of the building is ideal where space is a premium. Bird guard fitted as standard to stop damage by wildlife.
High efficiency low tonal noise backward curved centrifugal impellers are directly driven by an EC external rotor motor, provide low specific fan powers and stepless speed control without tonal noise generation.
Integral louvered air discharge provides protection against ingress from the elements and is self draining. No additional outlet duct fittings are required.
EC motors provide precise speed control via potentiometer, BMS or Elta Fans DCV control. Reduced fan speeds can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air.
Each SSDR has a 12 month warranty.
The unit casing shall be manufactured from 1.2mm thick natural finish Aluzinc. The casing shall be designed so as to minimise vibration and shall incorporate a louvred air discharge guarded against bird ingress. Each casing provides an inlet spigot to suit standard circular ducting. Top access panels shall be provided for ease of servicing.
Units shall havean EC external rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size. All motors are suitable for use in ambient air conditions up to +60 ℃.
High efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to ISO 14694 Grade G6.3 and directly driven by the motor to provide a smooth airflow through the unit.
Units shall be supplied with integrated commissioning controlallowing single speed selection and alsolimiting maximum speed if used with anexternal potentiometer.
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Singleflow SSDR units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
