the requirements stated in chapter 2.3 and repeated underneath.
Compressed air requirements
Pressure : 6-7 bar (90-100 PSI) (on the sorter connection)
Typical consumption : 400/1500 L/min (14/53 cfm) depending on confi guration
Max. consumption : 10000 L/min (177 cfm)
Quality : fi ltered 40 µm oil, water and dust free
Connection : 3/4” (3/4 inch) (Gaz)
Tubing : 2” (2 inch) tubes
Water requirements
Water pressure : between 1 and 3 bar (15 to 45 psi)
Temperature : between 5°C and 12°C (41°F to 54°F)
Max. consumption : +/- 500 l/h (132 gal/h)
Connection cooling water : 14 mm (0.55”) inside, inlet and outlet
Connection bottom clean : 3/4” (3/4 inch) (Gaz) inlet
Quality : lime-free and reusable (add glycol if necessary, see cooling manual).
When using distilled or demineralized water, please pay attention to the
compatibility with the materials and to the minimum conductivity that lever
sensor may relieve (80 µS). See Cooling Manual in Attachments.
Nitrogen specifi cations : N
2
- Grade 5.0
Purity (vol/vol%) : 99.999
Cylinder size-contents : B50 - 10 m³
Outlet nitro bottle must be : G 1/2” (inch) x 14, male
Attention! - It may be necessary for the Purchaser to buy a coupling piece if the
connections of local nitrogen bottles do not match these requirements.
- Take the necessary measures to prevent power surges and fl uctuations in the power supply of the
sorter unit, for this could seriously hinder its performance. The power supply has to be conform with
following requirements:
Electrical requirements
Voltages : 3 phase 400V (+ neutral & earthing)
Electrical power : 8 kVA
Frequency : 50 (or 60 Hz USA)
- Regularly inspect the tubing, the wiring, the valves and all connections on and around the GENIUS
Compact for leaks and breakages. (For more information on the connections see chapter 2)
- A Yearly check up by a certifi ed maintenance engineer from BESTnv or trained by BESTnv.
(It is advisable to plan this a few weeks/months before peak season).
- Replace all ejectors every three years.
Please contact the BESTnv service department if you have
any questions concerning this maintenance program.
