Overview
A multi-discharge, double skinned fan unit incorporating a high performance backward curved impeller. The motor is situated out of the airstream making the range suitable for more arduous and elevated temperature applications. Units are supplied as either an end inlet discharge unit (Qube SQUHT) or as a side inlet discharge unit (Qube SQUHTS)*.
Features and Benefits
High Temperature
Motors are out of the air stream and are not effected by contaminates in the ventilated air. The range is suitable for a wide range of applications from contaminated air to elevated temperatures up to 120 ℃.
Intelligent Design
Movable panels allow the inlet and outlet position to be altered on site to suit installation. DW172 models for kitchens meet system velocity requirements.
Low Noise
Units are constructed from double insulated panels filled with 25mm fibre glass acoustic insulation giving reduced noise levels.
Easy Maintenance
An easily removable motor/impeller assembly arrangement is ideal for frequent cleaning or maintenance.
Controllability
The Eltadrive range of inverters has 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.
Warranty
Each SQUHT has a 12 month warranty.
Specification
Casing
Constructed from self-supporting corrosion-resistant extruded Aluminium section, assembled with aluminium corners and 25mm thick double skinned removable panels, manufactured from pre-galvanised steel, in-filled with a non-flammable mineral wool, 60kg/m3, 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. Electrical connection is made directly to the IP55 motor terminal box.
Impellers
Impeller shall be high efficiency backward curved welded steel with a non-overloading power characteristic, suitable for continuous S1 operation up to +120 ℃, finished with a powder coating to 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 VSD Eltadrive VSD IP20 or Switched IP66 shall provide precisemotor 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-HT units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
