ProKiln GAC400
PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
23
Water Panel
The probe is made from high temperature resistant steel but, because of the extreme high temperature of a kiln inlet, it needs a
cooling system to sustain the operation.
The probe water panel serves to provide and monitor the cooling water supply. The water panel contains the water circulation pump,
which circulates the cooling water in a pressure-open system operating at ambient pressure level. A 300 l (approx. 80 gal US) water
tank serves as both a water and temperature buffer for the water-cooling system.
The water panel can be installed directly connected to the cooling panel or it can be installed within a maximum distance of 5 m
(16 ft 5 in) to the cooling panel.
The completely open system monitors the following parameters:
• Water pump operation
• Water tank temperature
• Water tank water levels
• Cooling water flow rate
