As summer temperatures rise, laser equipment enters one of the most demanding operating seasons of the year. High heat, humidity, and airborne dust significantly increase the risk of overheating, cooling system alerts, and accelerated aging of electrical components. These issues can compromise the stability and efficiency of your laser systems.
To ensure smooth, safe, and high-efficiency operation even during the peak of summer, Han’s Laser presents this all-in-one Summer Laser Equipment Maintenance Guide, covering key systems such as chillers, laser sources, and control cabinets. Let’s explore how to beat the heat and maintain peak performance all season long.
1.Chiller Cleaning and Cooling System Checks
The chiller plays a vital role in maintaining the proper temperature of the laser system. In summer, its performance is put to the test, and proactive care is essential.
Recommended Best Practices:
Maintain ambient temperatures below 40°C.
Set chilled water temperatures to:
- Low-temperature circuit: 23–25°C
- High-temperature circuit: 28–30°C
Ensure proper ventilation.
Keep at least 50 cm of clearance around air inlets and outlets to prevent airflow obstruction.
Replace distilled water regularly.
To prevent contamination and clogging, replace the chiller’s distilled water at least once every three months.
Clean dust buildup weekly.
Clean the water tank, filters, and condenser every week to maintain proper heat exchange and system hygiene.
2.Preventing Laser Source Condensation
Condensation is a major concern during hot, humid weather. When the laser surface temperature drops below the dew point of the surrounding air, moisture can condense on internal or external components. This may result in:
- Electrical short circuits
- Optical damage
- Laser power fluctuations
- Beam quality issues
Preventive Measures:
Install air conditioning in the laser room.
Keep the room temperature close to the chiller’s set temperature (e.g., if chiller water is set to 25°C, maintain room temperature between 23–27°C).
Control humidity.
If the environment is too humid, install a dehumidifier. Keep humidity below 50% to minimize condensation risk.
Reference dew point charts.
Use a temperature-humidity dew point chart to ensure the chiller’s water temperature is set above the local dew point, avoiding internal condensation.
3.Electrical Cabinet Inspection and Maintenance
In hot and humid summer conditions, the electrical control cabinet of a laser cutting machine operates under continuous high load and becomes a critical point of failure. Excessive temperature, moisture intrusion, dust accumulation, or loose wiring can easily lead to malfunctions, directly affecting the machine’s overall stability and operational safety. Therefore, regular inspection and maintenance of the control cabinet during summer is essential.
What to Check:
Inspect ventilation.
Regularly check if fans and vents are unobstructed. Clean dust from inside the cabinet every two weeks—more frequently in dusty environments.
Install dedicated air conditioning.
Keep cabinet temperatures below 35°C to protect sensitive components.
Clean filters regularly.
Replace filter foam and clean mesh filters to prevent airflow blockages.
Check for thermal expansion.
In high temperatures, copper busbars and wires may expand and contract. Check all connections for looseness and correct any issues to avoid electrical hazards.
Conclusion
Proper summer maintenance is not just about protecting your equipment—it’s about maintaining productivity, preventing downtime, and extending the lifespan of your laser systems. With Han’s Laser’s summer care recommendations, your machines can continue to run reliably and efficiently, even during the hottest months.
