Fiber Laser Equipment Chiller Maintenance Guide by Xianming Laser

To ensure the stable operation and long-term performance of your laser cutting machine, regular maintenance of the chiller is essential. Xianming Laser has compiled detailed guidelines to help you maintain your equipment scientifically and ensure your fiber laser equipment operates efficiently and reliably.

Summer Maintenance

It is recommended to clean the condenser and dust filter of the chiller approximately every 15 days.

Use an air gun or soft brush for cleaning to avoid damaging the cooling fins.

Winter Anti-Freeze and Long-Term Storage

When transporting the equipment or leaving it unused for a long period, drain the water in the tank through the drain valve.

Loosen the drain plug under the pump to remove residual water inside the pump.

If nighttime temperatures drop below 2℃, it is recommended to keep the chiller running or add antifreeze to prevent damage.

Cleaning the Outlet Filter

Open the left-side panel near the control panel and locate the Y-type filter.

Use a wrench to turn the nut counterclockwise and remove the filter mesh.

Clean the filter thoroughly with an air gun or water to remove debris.

After cleaning, tighten the nut clockwise with a wrench.

Replacing with Pure Water or Deionized Water

Open the drain valve to remove the antifreeze from the chiller.

Close the drain valve, add pure water or deionized water from the filling port, and run the chiller to dilute any remaining antifreeze.

Drain the diluted antifreeze again through the drain valve. Repeat this step 2–3 times.

Finally, add pure water or deionized water until the water level reaches the green zone on the display.

Daily Maintenance Notes

During routine maintenance, any damaged parts should be replaced immediately.

This not only protects the chiller but also ensures the laser cutting machine continues to deliver optimal cutting performance.

Maintaining the chiller is not only a protection for the equipment itself but also a foundation for the continuous and efficient operation of fiber laser equipment. Whether it is a fiber laser welding machine or a fiber laser cutting system, regularly cleaning the filters, draining antifreeze, and replenishing pure water can extend equipment life and improve processing quality. Consistent, scientific maintenance allows laser technology to deliver maximum value in your production.
