SQU82 560 EC 3 Qube Centrifugal Box Fan Three Phase EC 560mm

The Elta Qube SQU82/560-EC-3 is a centrifugal box fan with a 560mm backward curved impeller in a 820mm cube casing, for supply or extract air up to +40°C. It moves up to 12330 m³/h at free air on full (10V) speed and 9371 m³/h at 500 Pa, the highest pressure in Elta's performance table for this model.The three phase IE6 EC motor (380-480V 50/60Hz) is IP55, has a built in variable speed drive with protection against overload, over temperature and locked rotor, and takes a 2-10V or potentiometer speed signal, with volt free fault contacts for a BMS. The impeller is EN-AW 5754 aluminium, non-overloading and balanced to G6.3, inside an extruded aluminium frame with 25mm double skinned, mineral wool filled panels that can be moved to give a 90° or straight through airflow. Elta give a 24 month warranty. 3 Phase EC Motor Up to 12330 m³/h Speed Controllable What it is best used forGeneral supply or extract on a ducted system: a factory or warehouse bay, a large sports hall or an industrial unit. Elta list kitchens, schools, colleges, shops, sports halls, factories, industrial units and warehousing among typical uses. It moves 12330 m³/h free air and about 11138 m³/h against 200 Pa; at that 200 Pa figure it gives roughly 10 air changes an hour in a space of about 1110 m³.It is the wrong fan for hot extract: the Qube SQU is for an airstream up to +40°C, and Elta state it is not suitable for corrosive or explosive atmospheres. For hot or grease laden kitchen canopy extract, choose a Qube SQUHT high temperature box fan, which keeps the motor out of the air stream and is rated to +120°C in the duct.Why choose this over alternativesAn EC Qube needs no separate inverter: the drive is built into the motor, so speed is set from a simple potentiometer or a 2-10V BMS signal, and turning it down saves energy. At 7.5V this model gives 9144 m³/h free air and at 5V 5742 m³/h, so one fan can be commissioned to the exact duty. The Elta SQU82/560-4-3 is the AC version in the same box size, which runs at fixed speed or from a separate inverter.For less air, the Elta SQU82/500-EC-3 gives 8996 m³/h free air. For more, the Elta SQU82/630-EC-3 gives 16236 m³/h. For hot or greasy air up to +120°C, the Elta SQUHT82/560-EC-3 is the high temperature version with the same box and impeller size.Installation notes The fan can be mounted at any angle. It arrives set up for 90° airflow; move the panels to make it straight through if your duct runs in line. Make sure it is adequately supported, as it weighs 94 kg. Leave access to the panels: they are fixed with multi thread U nuts and lift off for cleaning and maintenance. Elta recommend an inspection at least every 12 months. Wire to Elta diagram 152-734 with a means of isolation. For external speed control from the 149-POT-10-MI or a BMS, remove the jumper on the control board. Elta give a maximum control cable length of 30m for the 2-10V signal; NC and NO fault contacts are provided for a BMS or alarm. Disconnect the fan before any insulation resistance testing, as the test can damage the EC electronics and that is not covered by warranty. The motor has an auto reset thermal contact, so isolate the supply before working on it because it can restart once cool. Elta rate the Qube for ambient temperatures of -20°C to +50°C and up to 95% relative humidity, with the three phase EC models limited to a 40°C airstream. Site the discharge so it cannot pull flue gases back from any open flued appliance. You'll also need Elta EC Electronic Controller 149-POT-10-MI for manual speed control (Elta's listed controller for this fan). Elta electric heater battery 018-RH100/50-27-3TP or 018-RH100/50-54-3TP, if you need to temper supply air. Available to order, ask us.
