ProKiln GAC400 PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
Cooling panel
The probe cooling panel serves to cool the water supply. The
cooling panel contains the air-to-water heat exchanger. The
cooling panel can be installed directly connected to the water
panel or it can be installed within maximum 5 meters to the
water panel.

Emergency stop
Transformer – power supply (optional)
The system is not supplied with a customized transformer. If a
transformer is required to meet the probe gas sampling system
power specifications it should be acquired locally in order to
meet local standards and legislation.
Function
Cools down hot water from probe
Provides cool water to tank/probe
Air-to-water heat exchanger
Turns off fan
Compressed-air system
The compressed-air is used for probe filter blow-back and air
blaster cleaning of the centre and periphery nozzles in the tip of
the probe.
The compressed air system also serves to operate the optional
flange shutter.
Requirements
The compressed-air must meet the following minimum
requirements:
Category
3
Dew point
Pressure
Consumption
Quality
Compressed-air tank
3
A dedicated air tank of minimum 250 l is required with minimum
a 1" connection for air supply and 1" connections to the
retraction unit. The air tank must be placed as close to the
retractor unit as possible, taking site conditions and potential
heat radiation into account.
The air tank must be equipped with oil and water cleaning
devices on the supply side of the tank. The compressed-air
supplied to the tank must be based on above specifications. No
oil and water cleaning devices must be placed between the
compressed-air tank and the compressed-air connection points
on the retractor unit as this will reduce the air delivered for
probe cleaning by the air blasters.
A locally acquired air tank should be installed in order to meet
local standards and legislation.
Requirement
0°C (for temperatures below 0°C make sure that the
compressed-air supply cannot freeze)
