Cooling water
8.3.1
Quality of cooling water
Distilled water causes immediate corrosion on bare parts, which is often unno-
ticeable at first, but later leads to serious corrosion damage.
Ü
Do not use pure or distilled water.
Deposits in cooling channels due to unsuitable cooling water prevent the dis-
sipation of heat.
Ü
Use cooling water with the following properties:
Drinking water
according to
98/83/EC
Hardness
1-15°dH
PH value
7-9
Additive (corrosion protection)
20% Antifrogen N
8.3.2
Setting the cooling
Ü
Observe the following values for liquid cooling:
Hose diameter (*)
Min. DN 5.5
Feed temperature
Min. 20°C
Volumetric flow
Min. 1.5 l/min
Return temperature
Max. 40°C
(*) Use cooling hoses that are impermeable to UV light.
