ProKiln GAC400 PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
Installing the cooling water hoses
Cooling water tubes or hoses are not supplied together with the system and are to be sourced locally according to local regulations.
Note the following recommendations when sourcing the tubes:
• Preferably use tubes made of galvanized steel or high-pressure, high-temperature flexible hoses. Do not use copper tubes, as this
could lead to galvanic corrosion.
• Install cooling-water tubes to avoid any damage caused by working in the proximity of the probe gas sampling system.
• Install tubes on trays or in tube conduits if possible, for further protection.
• Notice the minimum and maximum operational temperature allowed for the tubes and consult with tube manufacturer in case of
doubt.
• Only use hoses in areas where no heat or mechanical wear occurs.
• 1" hoses between Water panel and Cooling panel are included for install next to each other. If distance is larger than the length of
the hoses 1", tubing as described above is used.

Recommendations
1. The distance between the water system and the cooling unit should be minimized.
Ideal distance: 0,5 - 1 m.
2. The distance between the water system and the probe retractor should be minimized.
Ideal distance: 10 - 20 m.
This distance is ideal in order to avoid dust and hot space close to the kiln.
3. Also take ambient and site conditions into account:
• Avoid direct sunshine
• Prevent cold winter winds
• If ambient temperature gets below 5°C, use antifreeze and / or a tank heater (optional).
