General Information
Function:
The JUN-AIR Dryer uses the pressure swing adsorption principle
of drying compressed air, utilizing two identical columns each
containing a hygroscopic desiccant bed.
Dryer Operation:
Air at elevated temperatures exiting the compressor is routed
through an after-cooler. After being cooled, the air enters the dryer
through a shuttle valve (a) and is directed into one of the desiccant
columns. Each column contains a unique desiccant cartridge which
incorporates inlet and outlet filtration.
Bulk liquids (water) and particles are removed by the filtration/
separation stage (b) which is located on the inlet to the cartridge.
Water is retained in a "quiet zone" until the column is regenerated
(when it will be vented to atmosphere as the column is depressurized).
Following the filtration stage, air passes through the desiccant bed (c)
where any remaining moisture is adsorbed by the desiccant beads.
After drying, the air passes through another particle filter (d),
which retains any remaining desiccant particles that may have
been carried through the system (<1 µm / ISO 8573.1 class 2 dust).
Simultaneously, a small amount of dry air is counter-flowed down
through the other cartridge and exhausted to atmosphere, removing
the moisture and thus regenerating that desiccant column.
The dryer is controlled by a PLC which periodically switches the
solenoid valves when the compressor is running, reversing the
function of each column and therefore ensuring the continuous
supply of clean and dry air.
WARNING: Do not tamper with outlet tubing from the
exhaust ports on the dryer solenoid.
In order for the dryer to function properly, the exhaust ports on the
dryer must be routed to the collection bottle through included 8mm
tubes.
If the tubing to the collection bottle is restricted or changed, a
reduction in performance will occur. This will void the warranty on
the dryer and system.
PLC Operation:
The iQ-Dryer comes ready to operate. The PLC in the system displays
the total run hours, total number of system cycles, and the individual
dryer column cycle count. This is displayed on the main screen. The
following is a description of the controls, connections and common
displays for the PLC.
