Features
1. Less than 5% purge air without auxiliary equipment, 012KW power consumption
2. Pressure and inlet temperature is digital readout on screen; purge air gauge allows manually
control regeneration air according to the wanted pressure dew point
3. Small desiccant chambers' group, each chamber unit is independent and detachable
4. Replace with factory filled desiccant chamber, ease of maintenance and constant pressure dew
point -40C (-40F) is ensured
5. The lowest operation cost, user could recoup dryer investment in three years by saving huge
air and electricity
6. 1/3 size to traditional dryer
7. The shortest downtime
8. Using Molecular sieve as desiccant
How it works
Drying cycle
The process air enters the dryer through the inlet and is directed into the on-line drying chamber
via the inlet valves and lower manifold.
The air is evenly distributed through the drying units and passes over the desiccant material,
reducing the water vapour content.
The dried process air then combines in the upper manifold and exits the dryer via the outlet
check valves.
Column changeover
Before the on-line (drying) and off-line (regenerating) columns change over, the dryer exhaust valve,
is closed, allowing the purge air to re-pressurise the off-line columns. This ensures a consistent
system pressure and dewpoint when the drying chambers change over.
Regeneration cycle
At the start of the regeneration cycle, the exhaust valve of the dryer is closed and the off-line
chamber is at full line pressure. The air in the off-line chamber has a dewpoint equal to the air
leaving the dryer.
The exhaust valve is then opened and the dry air within the chamber expands rapidly as it
leaves the dryer via the exhaust silencer, forcing water to be removed from the desiccant material.
Once the off-line chamber has de-pressurised, a continuous bleed of dried process air is directed
into the off-line upper manifold. This air is known as purge air.
With the exhaust valve open, the purge air expands from line pressure to atmospheric pressure
and flows downwards through the columns, over the off-line desiccant material.
As the purge air at line pressure contains a fixed amount of water vapour, allowing it to expand
means the purge air becomes even drier, increasing its capacity to remove water from the
saturated desiccant bed.
Details of advantages
Â
Innovative structure with patents, adopts small desiccant chamber unit
Â
1. Air flow equally and evenly pass through each desiccant chamber
2. Avoid channeling effect which more likely happens in traditional desiccant dryer
3. Small chamber allow no pressure vessel annul inspection
4. Molecular sieve capability is much better than Alumina and silicon desiccant in traditional dryer
5. Easy to maintain and replace factory filled desiccant chamber unit, ensure good performance
as beginning
6. PLC controller, Full function touch panel control
