How to Prevent Condensation on a Laser Marking Machine in Winter
During the winter, low temperatures and fluctuating humidity can cause condensation on your laser marking machine. This can affect the machine's operation and potentially damage its optical and electronic components. Here are some effective measures to prevent condensation.

Solutions for Condensation
# 1. Adjust the Chiller Temperature
In winter, you should increase the chiller's set temperature to be closer to the room's temperature. A setting of around 25°C is generally recommended. If the indoor temperature is very low, you can raise it to 28-30°C to prevent condensation caused by a large temperature difference.
# 2. Keep the Machine Running
* Warm-up Before Use: Before operating the machine, turn it on to let it warm up for a while. This allows the internal components to reach a stable temperature, reducing the likelihood of condensation.
* Keep It On: If possible, keep the laser marking machine powered on, even overnight. You can turn off just the chiller. This allows the internal fans or dehumidifier to run continuously, maintaining a stable internal environment.
# 3. Use Antifreeze
In extremely cold weather, add a specialized antifreeze to the cooling liquid to prevent the system from freezing. Antifreeze lowers the freezing point of the liquid, protecting the cooling system's pipes from damage.
# 4. Optimize the Work Environment
* Maintain Room Temperature: Keep the laser marking machine in an environment where the temperature is no lower than 5°C. If possible, use an air conditioner or heater to maintain a temperature between 5-35°C.
* Control Humidity: Ensure the humidity in the work environment is below 60%. High humidity can easily lead to condensation, which can degrade performance and damage the machine.
# 5. Regular Inspection and Maintenance
* Check the Cooling System: Regularly check the water level and quality of the cooling system. Ensure the liquid is sufficient and clean, and replace it if it's cloudy or contains impurities.
* Clean the Machine: Regularly clean dust from the machine's surface and interior. Good heat dissipation reduces the temperature difference between the machine's inside and the outside, lowering the risk of condensation.
* Check Optical Components: Before use, check the optical components for cleanliness. If you find any water droplets or frost on the lens surface, wipe them off immediately and take steps to increase the ambient temperature.

Important Considerations
* Avoid Drastic Temperature Changes: When turning the machine on or off, try to avoid large temperature differences between the machine's interior and the outside environment. When starting, turn on the chiller first and wait until the temperature is below 30°C before starting the laser. When shutting down, slowly reduce the current to about 10A and stop the power output before turning off the chiller.
* Handling During Long-Term Storage: If the machine won't be used for a long time or if there's a power outage, be sure to drain the water from the chiller and store the machine in an environment above 5°C. This prevents the internal pipes of the cooling system from freezing and cracking.
By following these measures, you can effectively prevent condensation on your laser marking machine during the winter, ensuring its normal operation and longevity. If condensation has already occurred, immediately shut down the machine, wipe off any moisture on the casing, and wait for it to fully dry before resuming operation.
