custom coolant mix for hot operating temperatures
water purity requirements
custom coolant mix for hot operating temperatures (above 38° c / 100° F)
Treated water (with no propylene glycol) can only be used as coolant when ambient temperatures are
never
below 0° C
(32° F). For operations in very warm temperatures, treated water will provide the best cooling properties.
Treated water refers to a mixture of purifi ed water, that meets the specifi cations below, and 1 part benzotriazole (BZT)
to 300 parts of water. BZT (128020) acts as a corrosion inhibitor for the copper based coolant system contained in the
plasma system.
water purity requirements
It is critical to maintain a low level of calcium carbonate in the coolant to avoid reduced performance of the torch or
cooling system.
Always use water that meets the minimum and maximum specifications in the table below when using a custom coolant
mix.
Water that does not meet the minimum purity specifications below can cause excessive deposits on the nozzle that will
alter the water flow and produce an unstable arc.
Water that does not meet the maximum purity specifications below can also cause problems. Deionized water that is too
pure will cause leaching problems with the coolant system plumbing.
Use water purified by any method (deionization, reverse osmosis, sand filters, water softeners, etc.) as long as the water
purity meets the specifications in the table below. Contact a water specialist for advice in choosing a water filtration
system.
