[[Has caption::laser cutter periphery| ]]

We have a "CW4000" water chiller that is dedicated to the laser cutter.

Never fire up the laser without proper cooling!

Filling

The unit is filled from the top where you can remove the clear plastic lid. If the temperature may drop below 5°C the laser cutter's manual advises the use of company-approved antifreeze (NOT the stuff for cars, apparently it can break the tubing and seals!). Pending first experiences, we may also need to think about an additional sterilizing agent in case algae or fungi start feeling at home in the water...

1st fill: just distilled water, 2020-3-12
