3. SUPERIOR FEATURES OF DRYING
1) Speedy Dehumidification
After recycling the drying agent by heat, the interlocked fan inside the electric drying unit starts to
operate for about 2 hours to accelerate the moisture absorption.
2) Exception Recovery Times
The interlocked fan tops operating when the door is open to ensure minimal inflow of outside am-
bient air. Once the doors are closed, this fan starts operating again to accelerate the moisture ab-
sorption inside dry cabinet.
3) Flexible Humidity Setting
Ultra low humidity 1-5%RH or low humidity 1-50%RH can be adjusted flexibly for various applica-
tions.
4) Convenient Digital Control Panel
Precise humidity setting is easily controlled by a front digital control panel without opening the
doors.
5) ESD Safe Design
Equipped with conductive paint, conductive glass doors, chrome steel shelves. Our drying cabinet
is perfectly protected against ESD.
6) Dust Free Design
Urethane casters and chrome steel shelves make the drying cabinet especially suitable for use in
various kinds of clean rooms.

4. DEHUMIDIFICATION PROCESS
Our drying cabinet relies on a drying agent to control humidity lev-
els. This drying agent will be rejuvenated (recycled) for ½ hour in
every 6 hours. Its drying agent is completely recyclable and there is
no required maintenance. During the recycling period, absorbed
moisture will be discharged through the external shutter. After recy-
cling, the shutter will close and moisture inside dry cabinet will once
again be absorbed by the refreshed drying agent. This dehumidifica-
tion cycle will continue until the set humidity point is achieved. Once
the humidity level exceeds the setting level, this dehumidification
cycle will start again.
Every drying cabinet has contact switches installed on each of the doors to control a fan inside the
electric drying unit. The interlocked fan operates for about 2 hours after the drying agent is rejuve-
nated in order to accelerate moisture absorption. The interlock fan stops when the door is opened to
minimize inflow of ambient air into the unit. The interlock fan will operate for 20 minutes when the
doors are closed to speed up moisture absorption inside the drying cabinet.
5. INSTALLATION
Do not operate the drying cabinet near the shutter of air-conditioners, places with high temperature,
smoke and dust or a place with direct sunshine. Please use an extra metal plate, if necessary, to
place the drying cabinet in a stable place to avoid any instability for the glass doors.

8. Calibration
The calibration of a cabinet can be done in two different ways:
Exchanging the sensor. According to the effective ISO specifications it is recommended to
change the sensor every 12 to 24 Months by a new, calibrated sensor (incl. a calibration
report).
Calibrating / adjusting the offset value of the digital display.
Remark: Before calibrating, first a reference value must be determined with an additional calibrated
hygrometer (i.e. the cabinet atmosphere must be measured). Attention: do not measure the humidity
during the recycling mode of the drying unit!
Instruction
1. Unplug the main Power Plug.
2. Press both adjustment buttons (“UP” and “DOWN”), and keep pressed while plugging the
main power plug again. During this time the LED display is blank.
3. Press “ON / OFF”, the current offset value will be shown on the LED display.
4. Press the “SET” button to start the calibration, the current offset value on the LED display will
begin to flash.
(To end the calibration program and start the operation of SUPER DRY, press the “ON/OFF”
twice)
5. Adjust the humidity offset point with the “UP” or “DOWN” button:
“UP” increases, “DOWN” decreases the offset value . After finishing
adjustments press the “SET” button again. The new offset value will
be shown on the LED display.
E.g. the humidity display on the digital control panel is 3%RH, and the actual hu-
midity inside SUPER DRY is 1%RH, so set the offset value to 2 (3-1=2)
6. By pressing the “ON/OFF” button once, SUPER DRY will return to the standby condition.
To operate SUPER DRY, press the “ON/OFF” button a second time.
Press the “SET” button and follow the above instruction from point 3 to restart the calibration.
