    Coolant laser tube?

    Hi,

    I have Kaitian CO2 laser, 60W tube, and it's at a place which I can't warm every day, and the temperature can go UNDER -10 Celsius degrees (10 F) sometimes. Can I use antifreeze for cars? Do I really need to use destilled water and why? And, one more thing - how much is optimum operating temperature range for coolant?

    Greetings!

    Re: Coolant laser tube?

    I use RV antifreeze. It's a non toxic antifreeze used to replace the water in lines of trailers and houses that have no heat when not used. I circulate this fluid while the container sits in ice water. I'm targeting between 10 and 20 Deg C. I'm using a PC pump with a decent flow. I ales use a radiator that sits in the ice water. Cooling like this is inexpensive but necessary

    Do you use the RV antifreeze only, or mix with water? If mixed what sort of ratio?

    Thank you for your time and assistance.
