- Features & Benefits
Slim CasingThe compact design of the induction motors allow a shorter casing length, which means a lightweight unit that is easier to install, especially within restricted ductwork space.
Ease of installationFans are supplied with an integral IP55 terminal box which allows the fan to be positioned conveniently to incoming electrical inputs.
SafetyAll motors are fitted with integral ‘Thermal overload protection’ preventing the motor from overheating.
Cost effectiveVery efficient for moving high volumes of air at relatively low pressures.
Flexible performanceAdjustable pitch aerodynamic impellers allow easy site adjustment of the impeller from factory set maximum pitch angles if required
Speed controllableEach fan is fully speed controllable with an electronic or transformer controller, which means the airflow can be altered to suit site conditions.
Quality assuranceAll units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
CasingThe all metal fan casing provides a long lasting and robust construction.The units have been constructed from mild steel and suitably treated to ensure full corrosion protection, with both motors and axial impellers mounted within the length of the unit casing. All casing parts shall have a powder coated polyester epoxy paint finish in pastel beige (RAL 7032).
MotorsThree phase multi-voltage motors are wound for either (Delta) 230V/3Ph/50Hz or (Star) 400V/3Ph/50Hz connection, suitable for speed control when used with the Eltadrive VSD range of frequency inverter controls. Fans are suitable for operating temperatures between -20°C and +70°C fixed speed and -20°C and +50°C when used with a speed controller. Electrical connection to the motor is provided by an IP55 terminal box which is fitted onto the outer side of the fan casing.
ImpellersAdjustable pitch aerofoil impellers are provided with blades made from high quality GRP. Impellers are factory set at an angle to provide maximum performance. The hubs are manufactured from die cast aluminium alloy (LM24). Assembled impellers are to be dynamically balanced to ISO 14694 Grade G6.3.
Quality ManagementUnits are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All SCD units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
