Laser Device Winter Anti-Freezing Guide In colder climates, protecting laser equipment from freezing is critical to ensure reliable performance. Important steps include extending the warm-up time after transportation, monitoring water chiller temperatures, and using antifreeze suited to the local climate. Proper antifreeze dilution can help adjust the freezing point when needed. Additionally, draining the cooling liquid before long-term storage or transportation prevents ice-related damage. Following these precautions will safeguard laser devices during winter conditions.
