Figure 3-10 The percentage of ethylene propylene glycol and freezing point

Note:

the percentage composition of ethylene propylene glycol should not exceed 50%.

) .

The treated water works better when used in warm environment.
The treated water is a mixed water of pure water(which meet the below purity standard)
and benzotriazole with percentage of 300:1. As a corrosion inhibitor, benzotriazole is
suitable for copper cooling system included in plasma system.
