Hi Guys,
I have a 8HP liquid cooled spindle in a early 2000's vintage German CNC router. I bought the machine inoperative and I am getting it back online after a 8 year nap. The manuals say to use 20% glycol. But despite mentioning 20% glycol multiple times, it never says ethylene or propylene.
There is a little bit of green in the chiller tank. So my guess is that the proverbial last guy was running automotive coolant. The system is closed loop and it has a covered tank in the cooler. It is not pressurized beyond the pressure from the 1/2 HP circulation pump.
Should I just do 1 part automotive coolant concentrate to 4 parts de-ionized water and call it a day?
Thanks
