Here in the UK Winter is coming and if anyone, like me, has their glass-tube laser located in an outside workshop and lives in a similar seasonal location, it is always wise to take precautions to prevent a cooling system freeze-up.
I have a 5 deg.C ‘frost-stat’ workshop heater but that could fail so my laser tube cooling system comprises Distilled water with 30% vehicle antifreeze added. The system is closed-loop and fully contained but precautions must always be taken to ensure that children or pets cannot possibly gain access to the coolant.
WARNING – If you use antifreeze please be aware that it is a particularly dangerous substance and can, even in extremely small quantities, be deadly to cats as well as extremely toxic to young children.
