APPENDIX B : COMPRESSOR DRIVEN AIRDRYER
20950 Issue 1 April 98
B--7
DESCRIPTION
Airdryer -- General
The airdryer system is contained in a stainless steel cabinet with a door
fastened by a lock. A flange along the top of the cabinet provides fixing
holes, enabling the dryer to be fitted to the printer stand or to be wall
mounted.
CAUTION
The airdryer must be mounted in the upright
position.
The airdryer is shown in two general views (see Pg. B--8), with the
block diagram below giving a schematic view of its operation.
Air is drawn in by the compressor and supplied at a pressure of
approximately 4bar to the Peltier heatsink assembly. Increasing the air
pressure above atmospheric pressure reduces its dew point and, in the
Peltier heatsink assembly, the temperature of the pressurised air is
reduced to approximately 5
°
C. The moisture in the air condenses and
is trapped in the Peltier heatsink assembly. The dry compressed air
then passes through a filter to a pressure regulator and a needle valve
restrictor. The regulator maintains a fixed pressure of 2bar and the
restrictor valve maintains a fixed flow rate from the airdryer of 2.0 to
2.2 litres/minute to the print head.
