How to Prevent Laser Chiller Condensation in Summer
2025-08-21
High heat and high humidity in summer create the perfect conditions for a hidden enemy of laser systems: condensation. Once moisture forms on your laser equipment, it can cause downtime, short circuits, and even irreversible damage. To help you avoid this risk, TEYU S&A chiller engineers share key tips on how to prevent and handle condensation in summer.
1. Laser Chiller: The Key Weapon Against Condensation
A properly set laser chiller is the most effective way to stop dew formation on sensitive laser components.
Correct Water Temperature Settings: Always keep the chiller water temperature above the dew point temperature of your workshop. Since dew point depends on both air temperature and humidity, we recommend referring to a temperature–humidity dew point chart before adjusting settings. This simple step keeps condensation away from your system.
Protecting the Laser Head: Pay special attention to the optics circuit cooling water temperature. Setting it correctly is essential to safeguard the laser head from moisture damage. If you are unsure how to adjust the settings on your chiller thermostat, contact our technical support team at service@teyuchiller.com.
2. What to Do If Condensation Occurs
If you notice condensation forming on your laser equipment, immediate action is critical to minimize damage:
Shut down and power off: This prevents short circuits and electrical failures.
Wipe off condensation: Use a dry cloth to remove moisture from the equipment surface.
Reduce ambient humidity: Run exhaust fans or a dehumidifier to quickly lower humidity levels around the equipment.
Preheat before restarting: Once humidity drops, preheat the machine for 30–40 minutes. This gradually raises the equipment temperature and helps prevent condensation from returning.
Final Thoughts
Summer humidity can be a serious challenge for laser equipment. By setting your chiller correctly and taking quick action if condensation occurs, you can protect your system, extend its lifespan, and ensure stable operation. TEYU S&A industrial chillers are designed with precise temperature control to give your laser equipment the best protection against condensation.
