I just purchased a 80watt laser so I am new to the laser world. Can someone tell me if it is safe to put an anti-freeze in the water
for the chiller? Winter is coming.

Do not use anti freeze.
Either drain the water or put a heater in the water (aquarium heater) to maintain temp.
I would also recommend putting a block heater in the laser to keep it and the glass tube above freezing.

I have a 400-watt laser that I got last Christmas. Mine requires a chiller rather than a cooler, so I ask the manufacture the same question. Automotive anti-freeze will not cause any problems, at least for my machine. Gary

I have been using the pink RV antifreeze in mine for 4 years now
