BT - High Pressure Twin Fans

Description

Overview

The New BT Twin units are constructed to the highest manufacturing standards and developed around a rigid anodised aluminium extruded frame. Panels shall be manufactured from prime quality galvanised or plastisol sheet steel, fixed to the frame, ensuring a robust casing, for those tough site conditions.

Fan / Motor Assembly

Units are twin forward curved, double inlet double width centrifugal impellers, driven by totally enclosed fan ventilated motors, wound to suit either 220-240V/1ph/50Hz or 380-415V/3ph/50Hz electrical supply, with special voltage motors available on request.

The fan and motors are assembled on a rigid angle iron framework, fitted with anti-vibration mounts and a flexible connection between the unit casing and frame to ensure vibration free operation.

The motors are protected to IP55, against dust and water jets complying with BS EN 60529. With motor insulation Class F as a minimum, suitable for operating temperatures up to +55°C. All belt driven fans have metric pulleys to ISO 4183 and wedge belts to ISO 4184 and DIN 7753.

Protection of the motor is to be provided by a current overload protection switch such as a D.O.L. starter or equivalent which is required on all installations or the product guarantee will be invalidated.

Twin Fan Controllers

The BT range offers a guaranteed operation in the unlikely event of fan failure. A full range of control packages are available with facilities of Auto Changeover on fan failure, 24hr Duty Share, BMS compatibility, Night Time Setback and sensor connections for Optical Timelocks, Humidity Sensors, Air Quality Sensors and PIR Detectors.
