CKD GX8200 Series User manual

Refrigerating Type Air Dryer
GX8200 Series
CC-994A 6

GX8200
Stainless steel heat exchanger
compatible with oil-free air.
Dust can be prevented with heat exchanger
that adopts new stainless steel vessel.

Highly reliable snap drain is installed
With installation of a highly reliable snap drain, condensate
can be drained completely. Manual drainage can be made
without stopping the dryer.

Increased weathering performance
Corrosion resistance has been improved significantly with
application of nickel plating refrigerant piping by
the copper inside the heat exchanger unit.
High quality and high reliability
Point 1

Adoption of drain system that has less air loss 
Although the previous solenoid valve type suffered air loss
when the loads were lower, air loss is minimized by the
adoption of the float type. There is no air loss since the
condensate is drained from time to time when collected from
the dryer. 

Low pressure loss
Low pressure loss of less than 0.02MPa during rated
operation was realized.
Energy Saving
Point 2

Only look at the
operation panel for
checking.
Operating status can be
checked at a glance of
the refrigerant pressure gauge and
operating light.

External drain discharger
Drain discharger requires a daily check.
Easy maintenance without stopping the
dryer by the adoption of an external drain
discharger that requires adailycheck.

Dust filter equipped as standard
Dirt adhering to the dust filter can be
cleaned as that of an air conditioner.
Easy care and cleaning.

Enables central control in the factory
Easy maintenance
Point 4

※ Use corrosion resistant piping materials such as galvanized steel lining applied or stainless steel pipes. Install an air filter
just before the dryer depending on piping material if abnormal objects such as rust or peeling may arise inside thepiping.
※ Install an filter that removes contaminating substances inside piping just before installed equipment.
※ Note for oil Grade 1 : If the inlet oil paper exceeds 0.005mg/m3, install an X type filter additionally.

Please select model that has value of used air content calculation result below.
Processing air ow of dryer= Standard air ow × [ Correction coefcient for each model × Temperature correction coefcient (In air
temperature •Pressure dew point • Ambient temperature)] × Pressure correction coefcient
Note: ( Correction coefcient for each model × Temperature correction coefcient)’s maximum value is Maximum
coefcient.
In case ( Correction coefcient for each model × Temperature correction coefcient) exceeds this value, please
calculate by Maximum coefcient.
<Calculation example>
For GX8215D with Inlet temperature 35°C • Ambient temperature 32°C • Outlet pressure dew point 10°C • Air pressure 0.7MPa,
calculate process amount:
( Correction coefcient for each model × Temperature correction coefcient) = 0.9 × 1.38 = 1.242
Since it does not surpass GX8215D’s maximum coefcient of 1.53, dryer processing air ow is:
2.80 (Standard processing air ow) × 1.242 × 1.0 = 3.47 m3/min

Manufacturer's Liability
Illegal modications or repairs using nonstandard parts
by user.
WARNING
Design & Selection
AppIications
Use for applications other than dehumidifying compressed
air is prohibited.
This product must not be used for medical devices
for caisson shields or breathing devices.
CAUTION
Do not mount and use this device onto transportation
equipment such as vehicles or ships.
In case of using the air dryer in the compressed air
line with rapid compressor fluctuation, be sure to
install the air tank after the air dryer so that the
pressure uctuation becomes 0.34MPa/min or less.
If the pressure uctuation is rapid, it may result in
malfunction.
S udden burden changes may results in dew point’s
specification value changes. Hence, in case that
dew point efficiency must be strictly controlled,
please select model that has exibility on ability.
CAUTION

maximum working temperature.
If maximum working pressure is exceeded, install a
ventilation fan or air inlet, etc.
Do not install the product where it is subjected to
radiated heat.
Do not use this product where the temperature is
lower than the minimum working temperature.
Install the product in a well-ventilated place free of
dirt and dust.

CAUTION
Air pipe method
Pipe the dryer as the following diagram.
24 hour operation:
A parallel installation
for emergencies is
recommended.
Use a unit for normal
operation and the
other as a spare.
Galvanized steel pipes (white pipes) are recommended
for pipe materials. Use stainless steel pipes according
to specications and applications.
Intermittent operation:
Install the bypass
pipe for maintenance.
Install the lter if necessary to prevent dirt in piping
from entering the dryer.
Design piping so that pipe weight is not applied on
the product.
Use piping that sufficiently withstands working
pressure. Check that air does not leak from
connections.
CAUTION
Drain piping method
Insert the nylon drain tube piping of 5.7 to 6.0mm
inner diameter directly into the drain cock of the
drain discharger.
Keep the tube length within 5m, and leave the
discharge end open to the atmosphere.
If the drain piping slopes upward or if piping is too
long, drainage may not be discharged. Pipe with a
downward slope so that drainage is ows naturally.
If oil enters drainage, it must be drained and treated.
Contact an industrial waste specialist for treatment.
Securely x the drain discharge tube, etc., so that it
does not sway during drain discharge.
Fully open the ball valve installed before the drain
discharger during normal operation. Operate the
ball valve during maintenance.
