Chiller maintenance helps protect the glass laser tube in a Nova series laser machine and keeps the cooling system working reliably for longer. If a laser machine is used in a cold garage, a hot workshop, or an environment where algae may grow in the water tank, the chiller needs regular attention.

This guide explains how to maintain a chiller system, including first-time setup, routine cleaning, heat control, anti-freeze protection, and algae prevention.

1. Why Laser Chiller Maintenance Matters

A laser chiller controls the cooling water that protects the laser tube during operation. Poor maintenance can lead to low water levels, blocked airflow, overheating, freezing damage, or algae buildup inside the tank and tubing.

Regular checks are simple, but they make a major difference to the long-term performance of the laser system. The key is to keep the water level correct, use the right water, clean the chiller regularly, and adjust maintenance steps based on the season.

2. First-Time Chiller Setup

Before using the chiller for the first time, unscrew the lid and fill the empty tank with pure water until the water level reaches the green normal scale. Before each laser task, check that the water level is still within the green range.

If the water level drops to the red alarm scale, add more water. If the water reaches the yellow full scale, open the blowing mouth to release excess water and bring the level back to the proper range.

3. Routine Chiller Maintenance

Routine chiller maintenance should be carried out once or twice a month. The process is straightforward: clean the dust screen, open the water inlet cover, and use the blowing mouth to refresh the water.

After maintenance, check the water volume again in the same way you did during the first-time setup. This helps ensure the chiller is ready before the next laser job.

4. Heat Control for Chiller Maintenance

In hot weather, try to keep the machine’s working environment below 27 degrees Celsius. Avoid direct sunlight and keep air humidity below 70% to help the chiller work in a stable environment.

5. Anti-Freeze Protection in Cold Weather

The ideal operating temperature for the Nova series is 15-25 degrees Celsius. However, low-temperature weather may require special chiller maintenance to protect the laser tube and cooling system.

Damage to the laser tube caused by cold conditions or other natural causes may not be covered by warranty, so winter chiller care should not be overlooked.

6. Preventing Algae Growth

After coolant is added to the tank, nutrients in the system may promote algae growth. Preventing algae is an important part of long-term chiller maintenance.

To protect the tank from algae, add a small amount of suitable algaecide and cleaning additive when maintaining the chiller. Keeping the tank clean helps the cooling water circulate more reliably.
