Custom Coolant mix for cold operating temperatures
• Ambient temperature below -12° C / 10° F
• Chiller process temperature below 4° C / 39° F
CAUTION
For operating temperatures colder than the temperature stated above, the percentage of propylene
glycol must be increased. Failure to do so could result in a cracked torch head, hoses, or other damage
to the torch coolant system due to freezing.
Use the chart below to determine what percentage of propylene glycol to use in the mixture.
Mix 100% glycol (028873) with the premixed Hypertherm coolant (028872) to increase the percentage of glycol.
The 100% glycol solution can also be mixed with purifi ed water (see the chart below for water purity requirements) to
achieve the required protection from freezing.
Note: The maximum percentage of glycol should never exceed 50%. Increasing the percentage of glycol reduces
the capacity of the cooling system.
