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.
Impellers
A high efficiency backward curved welded steel impeller with a non-overloading power characteristic, suitable for continuous S1 operation up to +120°C, 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 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: 2008. All Slim QUBe SSQU-HT units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
