gas intake temperature 20°C (+68°F) measured at the inlet port and atmospheric backpressure 1013 mbar (abs.) (29.92 In
Hg).
The ambient temperature, and the conveyed gas intake temperature, is
permissible inside the range -15°C (+5°F) ÷ +40°C (+104°F) with the
following provisions;
•
for ambient temperature +30°C (+86°F) reduce the maximum
pressure differentials given in the "SPECIFICATIONS" by 5%;
•
for ambient temperature +40°C (+104°F) reduce
maximum pressure
"SPECIFICATIONS" by 10%.
The graph to be used to reduce the maximum pressure differentials in
case of ambient temperature between +21°C and +40°C (+70°F and
+104°F) is given below
The unit should not be installed at more than 1000m a.s.l.; if higher, contact the Rico after-sales service.
Danger due to limited visibility in the place where the unit is installed!
Make sure to always have the installed unit under control when carrying out any operation in the installation area.
The control elements must be placed so that the installed unit can be seen.
Danger of serious injury!
If the flow rate has to be reduced, use a bypass valve instead of throttling the suction or delivery.
ATTENTION!
•
in case of suction in the place or on the system, protect the intake pipe using a suitable filter with maximum filtration of 25µm.
For the use of filters with filtration different from 25µm, ask Rico. Check compliance with the maximum pressure / vacuum data
given in the SPECIFICATIONS (max ∆p).
•
for use as a blower deduct the pressure loss (P
P (for T =20°C and P
a ambient
•
for use as an exhauster make sure the maximum vacuum at the inlet port is not exceeded.
10.2 SPECIAL VERSIONS
Rico side channel blowers/exhausters can be manufactured in special or custom versions; the instructions given in this manual still
apply to some of them.
The special versions manufactured, and for which that given above applies, are:
•
BPA version
Machines built to work in harsh environments and/or for conveying aggressive fluids, where aggressive means the presence
of elements that can affect standard machine operation, such as humidity; as specified in point 2, conveying flammable,
explosive or toxic gases, or installation in potentially explosive places, is not permitted.
• TMS version
Machines that ensure mechanical seal between the parts that convey air or fluids, minimising leakage.
•
Special electric motors
On request, blowers/exhausters can be manufactured with motors having one or more of the following characteristics:
Special voltages
-
Higher levels of protection against solid bodies and/or liquids (standard IP55)
-
Higher insulation classes (standard Class F)
-
Protection devices such as thermal switches, PTC, PT100
-
Further customisation must be requested and agreed when ordering, subject to a feasibility appraisal by the Technical Department.
For maintenance of special version machines, contact Rico.
