1. Structure and feature of GSD series
+ Guarantee definite and fast dew point
+ Full-automatic unmanned operation and easy digital operation
+ Apply reliable operating evolve and secure abundant leeway and repayment
+ Cost reduction of operation by dew point operation (PPD-2)
2. Typical design condition
+ Entrance air pressure 7.0kg/cm²(SID) 10-50kg/m²(OPN)
+ Entrance air temperature. max 40°C
+ Exit guaranteed dew point - 40°C(SID), -75°C(OPN)
+ Operating cycle. 10min/cycle
3. Drying and operation principe of GSD series
Compressed air heaved in air compressor passes through adsorption fower adsorbent is
filled within regulated velocity and contact time through 3- Way
Shuttle Valve(2-Way Valve in case of high capacity) that is the entrance
valve of an air dryer and provides compressed air of required dew
point(generally -40°C=75°C)
Drying
and regenerating cycle are progressed by guaranteed dew point for 2-5
minutes when one adsorption tower(A) is in the progress of drying the
other adsorption tower(B) passes a part of the exit side dried air
through reducing valve and orifice and regenerates completely by
discharging water adsorbed in the previous cycle to the air.
The
merit of the GSD-Series air dryer is that control and regenerated air
can be controlled on the spot to reduce regenerated air by condition of
the entrance, indraft side compressed air as it can and it is to
maximize effect or energy reduction with dew point control operation
optionally together.
Furthermore, it is designed to prevent moment pressure drop in advance
by closing the valve when it is lower than regulated pressure, as senses the exit side pressure condition at all times
