Dryer section
The dryer section contains the following
main parts:
• Water separator 1
• Thermoelectric cooler
• Water separator 2
• Filter/solenoid valves
• Drainage bottle
• Standby solenoid valve
• Low pressure switch
• Standby pressure switch
• Pressure regulator
• Electric power supply
• Electrical interconnection
• Fuses
• Dust filters
• Fan.
Compressed air, supplied from the cooling
section, passes through water separator 1.
In this "water trap", some amount of water is
separated from the compressed air.
The air flow then passes through the
thermoelectric cooler where the air
temperature is further lowered. Moisture that
remains in the compressed air is then partly
transformed into water by condensation. This
water is separated from the air in water
separator 2.
The dried, compressed air from the air outlet
of water separator 2 is collected in the
compressed air reservoir.
Fan
A pressure regulator is connected to the
compressed air tubing. Air pressure in excess
of the preset level on this pressure regulator,
Low
normally approx. 400 kPa (4.0 bar), will
cause a flow which is fed back to the inlet of
the compressor via the air inlet silencer.
