How to Protect Your Laser Equipment from Dew in Spring Humidity

Spring humidity can be a threat to laser equipment. During the rainy season or in high-humidity workshops, condensation can form on laser equipment surfaces. This can lead to everything from system shutdowns to severe damage to core components. But don't worry—TEYU S&A Chiller is here to help you tackle the dew crisis with ease.

Dewing Crisis: The "Invisible Killer" for Lasers

1. What is Dewing?

When a laser system's surface temperature drops drastically due to traditional cooling methods, and the environmental humidity exceeds 60%, with the device temperature falling below the dew point, the water vapor in the air condenses into droplets on the equipment surface. It is similar to condensation forming on a cold soda bottle—this is the "dewing" phenomenon.

 

2. How Dewing Affects Laser Equipment?

Optical lenses fog up, leading to scattered beams and reduced processing accuracy.

Moisture short-circuits the circuit boards, causing system crashes and even potential fires.

Metal components rust easily, increasing maintenance costs!

3. The 3 Major Issues with Traditional Humidity Control Solutions

Air Conditioner Dehumidification: High energy consumption, limited coverage.

Desiccant Absorption: Requires frequent replacement and struggles with continuous high humidity.

Equipment Shutdown for Insulation: While it alleviates dewing, it affects production efficiency and is only a temporary fix.

 

Laser Chiller: The "Key Weapon" Against Dewing

1. Proper Water Temperature Settings of Chillers

To effectively prevent dew formation, set the water temperature of the chiller above the dew point temperature, considering both the actual working environment's temperature and humidity. The dew point varies with ambient temperature and humidity (please refer to the chart below). This helps avoid significant temperature differences that could lead to condensation.

 

2. Proper Water Temperature of the Optics Circuit of the Chiller to Protect the Laser Head

If you're unsure how to adjust the water temperature through the chiller controller, feel free to contact our technical support team via service@teyuchiller.com. They will patiently provide you with professional guidance.

What to Do After Dewing?

1. Power down the equipment and use a dry cloth to wipe off the condensed water.

2. Use exhaust fans or dehumidifiers to reduce humidity.

3. Once the humidity drops, preheat the equipment for 30-40 minutes before restarting to prevent further condensation.

As spring humidity sets in, it's crucial to focus on moisture prevention and maintenance for your laser equipment. By ensuring stable operation, you can keep your production running smoothly.

Efficient Cooling Solution for CNC Milling Machines with CW-6000 Industrial Chiller

CNC milling machines are indispensable in modern manufacturing for their precision and versatility, especially when working with high-power spindles. To ensure optimal performance and prevent overheating, effective cooling is crucial. 

Cooling Requirements for CNC Milling Machines

CNC milling machines, particularly those with powerful spindles, generate significant heat during operations. The spindle, responsible for rotating the cutting tool at high speeds, must be cooled effectively to maintain precision, prevent thermal damage, and extend the lifespan of the machine. Without proper cooling, the spindle could overheat, leading to reduced machining accuracy, increased wear, and even catastrophic failure.

A dedicated spindle chiller is essential for managing the temperature of the spindle and maintaining its operational efficiency.

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.
