Hello,
I am Building chiller for cnc water cooled spindle since the cw3000 is more comon on laser engravers i am posting here. for now i am using aquarion pump with bucket.
since machine is in my workshob there is large amount of dust and dirt. so i want to change it to chiller since cw3000 is basic radiator with fan i have buy for 10$ new car heater core sourced two 120mm 220v 25W fans and unstaled them in old pc mini tower now i need some closed reservoar. and my question is is the water reservoar on cw3000 air tight with seal or have small air vent hole on it? And is water circulation pump on cw3000 closed loop pump for circulation or is it just modified aquarium submersible pump that is used as circulation pump....
