All Echion-model pumps
Environmental conditions
Hydraulic fluid
A laboratory analysis of hydraulic fluid can tell you if replacement is recommended.
The maximum contamination from particulates that is permitted is19/17/14 when tested according
toISO 4406. The maximum recommended contamination from water is300 ppm when tested
according to ASTM D6304c-04. If it is not practical to analyze a sample of your hydraulic fluid,
Hypertherm recommends replacing it every3,000 hours.
Refer to Replace the hydraulic fluid on page 86.
Glycol can be added to the cooling circuit to prevent freezing, but glycol is less efficient for
cooling than water.
Hypertherm recommends using a solution of not more than25% glycol in chillers for this
system.
