Why Your CO2 Laser System Needs a Professional Chiller?

The Critical Role of CO2 Laser Chillers in Modern Applications

CO2 lasers are widely used in industries such as cutting, engraving, medical aesthetics, and more due to their high power and wavelength properties. However, laser tubes generate significant heat during operation, which can lead to temperature fluctuations of ±5°C or more. Without efficient cooling, this can result in:

1. Power Instability: Uncontrolled temperature variations reduce photon emission consistency, degrading cutting/engraving accuracy

2. Accelerated Component Degradation: Optics and laser tubes experience 68% faster aging at uncontrolled temperatures (Optical Engineering Journal, 2022)

3. Unplanned Downtime: Every 1°C overshoot beyond the optimal range increases system failure risk by 15% (Industrial Laser Solutions)

A professional CO2 laser chiller utilizes a closed-loop temperature control system (with precision of ±0.1~1°C) to maintain the laser tube temperature within the optimal operating range (usually 20~25°C), ensuring maximum energy conversion efficiency.

How Does a Chiller Work in CO2 Laser Equipment?

Cooling Principle: The CO2 laser chiller's refrigeration system cools the water, which is then pumped into the CO2 laser equipment. The coolant absorbs heat and warms up before returning to the chiller to be cooled again and recirculated back into the system.

Internal Refrigeration Cycle: The CO2 laser chiller's refrigeration system works by circulating coolant through an evaporator, where it absorbs heat from the returning water, evaporating into steam. The compressor then extracts the steam, compresses it, and sends the high-temperature, high-pressure steam to the condenser. In the condenser, heat is dissipated by a fan, causing the steam to condense into a high-pressure liquid. After passing through an expansion valve, the liquid refrigerant enters the evaporator, where it evaporates again, absorbing more heat. This process repeats, and users can monitor or adjust the water temperature using the temperature controller.

How to Store Your Water Chiller Safely During Holiday Downtime

As the long holiday approaches, proper care for your water chiller is essential to keep it in top condition and ensure smooth operations when you’re back to work. Remember to drain the water before the holiday. Here’s a quick guide from TEYU Chiller Manufacturer to help you protect your equipment during the break.

1. Drain the Cooling Water

In winter, leaving cooling water inside the water chiller can lead to freezing and pipe damage when temperatures drop below 0℃. Stagnant water can also cause scaling, clogging pipes, and reducing the performance and lifespan of the chiller machine. Even antifreeze can thicken over time, potentially affecting the pump and triggering alarms.

How to Drain Cooling Water:

① Open the drain and empty the water tank.

② Seal the high-temperature water inlet and outlet, as well as the low-temperature water inlet, with plugs (keep the filling port open).

③ Use a compressed air gun to blow through the low-temperature water outlet for approximately 80 seconds. After blowing, seal the outlet with a plug. It is recommended to attach a silicone ring to the front of the air gun to prevent air leakage during the process.

④ Repeat the process for the high-temperature water outlet, blowing for about 80 seconds, then seal it with a plug.

⑤ Blow air through the water-filling port until no water droplets remain.

⑥ Drainage finished.

Note:

1) When drying pipelines with an air gun, ensure the pressure does not exceed 0.6 MPa to prevent deformation of the Y-type filter screen.

2) Avoid using an air gun on connectors marked with yellow labels located above or beside the water inlet and outlet to prevent damage.

3) To minimize costs, collect antifreeze in a recovery container if it will be reused after the holiday period.

2. Store the Water Chiller

After cleaning and drying your chiller, store it in a safe, dry spot away from production areas. Cover it with a clean plastic or insulation bag to protect it from dust and moisture.

Taking these precautions not only reduces the risk of equipment failure but ensures you’re ready to hit the ground running after the holidays.
