Precautions For Using Lasers In Winter

Ambient temperature requirements for lasers

The ambient temperature of laser must be between 5°C and 45°C. If this range is exceeded, the laser may not only be unstable, but may even cause damage to the laser, such as freezing of the internal cooling water pipe.



Conditions that may cause the laser (water cooled machine) to freeze

1. The temperature is below 0°C, there is no heating facility, and the laser stops for a long time.

2. The temperature is below 0°C, there are heating facilities, but due to the heating and power supply stop during holidays (such as the Spring Festival), the laser stops for a long time.

3. The water cooler is placed outdoors.



Hazards caused by freezing of lasers (including chillers)

It is well known that the density of ice is less than that of water. Once the cooling water flowing through the inner core components of the laser freezes, the volume will expand, which may cause serious damage to the pipeline, which will seriously affect the safety of the core components and cause significant losses.



Matters needing attention

1. Ensure that the ambient temperature is higher than 0°C.

2. Keep the laser and water cooler on at all times to allow water to flow to prevent freezing

3. Drain water from the laser and water cooler tanks and pipes as much as possible

4. Add Klein antifreeze



After the winter, please pay attention to return to normal cooling water, and return to the original parameters. Before changing the water, thoroughly flush the antifreeze in the entire tank and piping before changing the water normally. Replace the deion cylinder at the same time as the water is replaced. Re-add water, be sure to empty the pump before opening it, otherwise it will damage the pump.
