Antifrogen® frost protection is dependent on the mixing ratio with water.
Recommended minimal usage concentration for
Antifrogen® KF is 20 % v/v.
Corrosion protection will be less effective for higher dilutions.
Antifrogen® N has the advantage of a higher frost resistance compared to Antifrogen® L.
On the other hand, Antifrogen® should not be used too highly concentrated because then
the heat transfer is poor and there is pressure drop.
Practical experience has shown frost resistance over the following temperature ranges to be adequate:
|Hot water heating systems
||-10 to -20°C
|Earth-buried collectors combined with heat pumps
||-10 to -15°C
|Other external circuits combined with heat pumps
||-20 to -25°C
||-10 to -40°C
|Leak detection fluid
Due to the mathematical calculation done by this program smaller deviations of individual physical characteristics may be observed.
