Requirements placed on the anti-corrosion agent
The anti-corrosion agent must fulfill the following requirements:
●
The basis is ethylene glycol (also called ethanediol)
●
The water and anti-corrosion agent do not segregate
●
The freezing point of the water used is reduced to at least -5 °C
●
The anti-corrosion agent used must be compatible with the fittings and cooling system
hoses used as well as the materials of the motor cooler
Check these requirements, especially in regard to material compatibility, with the cooling unit
manufacturer and the manufacturer of the anti-corrosion agent!
Suitable mixture
●
25% - 30% ethylene glycol (= ethanediol)
●
The water used contains a maximum of 2 g/l dissolved mineral salt and is largely free
from nitrates and phosphates
