Subject to EAR. ECCN EAR99 and related export control restrictions.
Actual air throughput = 75 x 1.07 x 0.93 x 0.65 x 1.25 = 61 scfm (104 m³/h)
61 scfm (104 m³/h) is the maximum flow rate of the dryer under the aforementioned operating conditions.
Selection of the best suitable model in accordance with the operating conditions:
Air throughput acc. to planning =
Requ. air throughput
Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)
Example:
The following operating parameters are known:
Required air mass = 100 scfm (170 m3/h)
Air inlet pressure = 120 psig (8 barg)
Ambient temperature = 105°F (40°C)
Air inlet temperature = 122°F (50°C)
Pressure dew point = 50°F (10°C)

Factor (F1) = 1.07
Factor (F2) = 0.93
Factor (F3) = 0.65
Factor (F4) = 1.25
To find out the correct dryer version, the required air mass must be divided by the correction factors of the parameters
indicated above:

= 124 scfm (211 m³/h)
1.07 x 0.93 x 0.65 x 1.25
The suitable model for these requirements is SR 125 (with a spec. nominal capacity of
125 scfm [212 m³/h]).
8.5 Connection to the compressed-air system
Danger!
Compressed air!
All works must only be carried out by qualified skilled personnel.
Never work on compressed-air systems which are under pressure.
The operator or the user must ensure that the dryer is never operated with a pressure exceeding the
maximum pressure value indicated on the name plate.
Exceeding the maximum operating pressure can be dangerous for the operator but also for the device.
The air temperature and the air flow at the inlet of the dryer must lie within the limit values indicated on the name
plate. The connecting lines must be free from dust, iron rust, shards and other contaminations and correspond to the
flow rate of the dryer. Should air with a very high temperature be treated, the installation of an aftercooler may be
necessary. For the implementation of maintenance works, the installation of a bypass system is recommended.
The dryer was designed in such a manner that vibrations that may occur during operation are limited. Therefore, it is
advisable to employ connecting lines (flexible hoses, vibration-inhibiting fittings etc.) which protect the dryer against
possible vibrations in the pipework.

Note!
Contaminated intake air!
In the event that the intake air is strongly contaminated (ISO 8573.1 class 3.-3) or poorer quality, we
recommend the additional installation of a prefilter (e.g. Sullair STX or SXF), to avoid clogging of the heat
exchanger.
8.6 Electrical connections
Danger!
Supply voltage!
The connection to the electric mains should only be carried out by qualified skilled personnel and must
correspond to the legal provisions in force in your region.
Prior to connecting the device, please check the name plate to avoid exceeding the indicated values. The voltage
tolerance is +/- 10%.
SR 10-480 AC dryers are supplied with a power cord and safety plug (two-pole and earth connection).
Make sure that suitable fuses or circuit breakers in accordance with the indications on the name plate are available.
A residual-current device (RCD) with In =0.03A is suggested. The cross-section of the power supply cable must
correspond to the power consumption of the dryer. In this respect, the ambient temperature, the cable laying
conditions, the length of the cables and the requirements of the local electricity supplier need to be considered.
Danger!
Supply voltage and missing earth connection!
Important: ensure that the plant is connected to earth.
Do not use plug adapters at the power plug.
Possible replacement of the power plug must only be carried out by a qualified electrician.
8.7 Condensate drain
Danger!
Compressed air and condensate under pressure!
The condensate is discharged at system pressure.
The drain pipe needs to be secured.
Never direct the condensate drain pipe at persons.
The dryer is delivered with an already integrated timed condensate drain or an electronically level-controlled Sullimax
condensate drain. Connect the condensate drain with a collection system or container by properly screwing it on.
Do not connect the drain with pressurised plants.
Do not discharge the condensate into the environment.
The condensate accumulating in the dryer contains oil particles which were released into the air by the
compressor.
Dispose of the condensate in accordance with the local provisions.
It is advisable to install a water-oil separator, to which the total amount of condensate from the
compressors, dryers, tanks, filters etc. is supplied.
We recommend SULLIPRO oil-water separators to threat compressor condensate
