Overview
A multi-discharge, double skinned fan unit incorporating a high performance backward curved impeller. Supplied for straight through airflow with the outlet panel positioned directly opposite the inlet panel. The outlet panel can be easily exchanged on-site to provide 90° airflow if required.
Features and Benefits
Intelligent Design
Movable panels allow the outlet position to be altered on site to suit installation.
Low Noise
Unit is constructed from double insulated panels filled with 25mm fibreglass acoustic insulation.
Controllability
The Eltadrive range of inverters has been designed encompassing the latest technology and combine robustness with reliability. Using an inverter to control fans via sensors to reduce fan speed can provide significant cost savings through lower energy consumption.
Warranty
Each SQU has a 12 month warranty.
Specification
Casing
Constructed from self-supporting corrosion-resistant extruded aluminium section. Straight through airflow as supplied. Discharge position can be altered on site. The inlet and outlet panels incorporate circular spigots with integral U-shaped ozone and UV stable EPDM rubber seals to prevent duct leakage. Assembled with shock resistant fibreglass reinforced Polyamide PA6 corners, and 25mm thick double skinned removable panels, manufactured from pre-galvanised steel, in-filled with a non-flammable mineral wool, 60kg/m_, thereby minimising breakout noise.
Motors
Three phase multi-voltage IP55 TEFC Foot / Flange mounted IEC frame motors, wound for either (Delta) 230V/3Ph/50Hz or (Star) at 400V/3Ph/50Hz connection, suitable for speed control when used with the Eltadrive VSD range of frequency inverter controls. Motors are pre-wired to an IP55 terminal box mounted on the side, for easy customer connection.
Impellers
A high efficiency backward curved welded steel impeller with a non-overloading power characteristic, finished with a powder coatingto RAL 5002 for greater surface protection, and dynamically balanced to G2.5 / G6.3 according to ISO1940 part 1.
Control
Speed control shall be via Eltadrive VSDEltadrive VSD IP20 or Switched IP66 shall provide precise motor control and energy savings. The Eltadrive range of inverters have been designed encompassing the latest technology and combining robustness with reliability. Using an inverter to control fans via sensors to reduce fan speed can provide significant cost-savings through lower energy consumption.
Quality Management
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Qube SQU units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
