With the sharp drop in winter temperatures, laser equipment is prone to malfunctions in low-temperature environments. In particular, laser water chillers are susceptible to freezing if the temperature drops too low. Since ice is less dense than water, freezing can cause the volume inside the water chiller and laser to expand, leading to rupture or deformation of the cooling water pipes and potentially causing significant damage to critical components. Therefore, taking adequate anti-freezing measures for laser water chillers is essential. Effective anti-freezing for laser equipment is crucial for maintaining operational efficiency.
I. Simple Anti-freezing Tips for Water Chillers
- Add Antifreeze: If the laser water chiller is exposed to a low-temperature environment where there is a risk of freezing, it is recommended to add antifreeze. The recommended ratio of antifreeze to water is 3:7 (3 parts antifreeze, 7 parts water). This anti-freezing measure can effectively resist temperatures as low as -20°C without freezing. This is a primary step in anti-freezing for laser equipment.
- Thoroughly Drain Water: If the laser is not used for an extended period and you cannot guarantee the indoor temperature, be sure to drain all the water from the laser and water chiller. Use compressed air to blow out any residual moisture from the pipes to prevent freezing. Alternatively, follow the first recommendation and add antifreeze. Proper drainage is a vital component of anti-freezing for laser equipment.
II. Special Reminders
- Replace Coolant in Time: After winter, when the temperature rises, be sure to replace the antifreeze with normal cooling water.
- Pay Attention to Low-Temperature Warnings: If the external ambient temperature is too low, the following fault may occur in the water tank: The temperature controller flashes a warning. The solution is to use external heating (such as directly adding hot water) to raise the water temperature in the tank to above 15°C, and the alarm will be automatically cleared. Monitoring for these warnings is part of a comprehensive anti-freezing for laser equipment strategy.
Anti-freezing for laser equipment is a multi-faceted approach, combining preventative measures with attentive monitoring.
