How to protect your laser tube from being broken by frozen water in winter

views: 4417times 2017-06-29

In winter, the air temperature is close to 0℃ in many areas all over the world. If the ambient temperature is too low, it may result in water freezing inside the co2 glass laser tube and water chiller, end up with laser tube broken and damages to chiller. If you can’t remember to dry the laser tube and chiller every time when you shut down the machine, you may need some solution for anti freezing of coolant.

 

The optional choices to keep cooling water from freezing:


1. Keep chiller running with no stop and make sure the water flowing continuously.


2. Drain water away from the chiller and glass laser tube after stopping the machine every day.


3. Add anti-freeze product recommended by us into cooling water.


 

If the option 1 and 2 are not practical for you, then anti-freeze product is necessary and helpful. The brand we recommend is “CLARIANT”, and these 2 models as below are suitable for laser products.


1) Antifrogen®N (Industry use)


2) Antifrogen®L (Food class)


The mixed ratio is 3:7 (anti-freeze fluid: cooling water), it can be no freeze under -20℃.


Other brand anti-freeze fluid like SINOPEC: FD-1 may cause laser tube damages, such as unstable laser beam, abnormal noise, laser power decreasing more than 10watt and lifetime reduction. In the coming future, we will do more test on other brands of anti-freeze fluid to get more options for customers to choose.

 

NOTICE:


Please choose recommended anti-freeze product, otherwise it may cause damage to the laser tube.

 

Steps to follow for adding anti-freeze fluid:


1. Drain cooling water away from chiller water tank and clean it.


2. Remove the clean water cap and replace the filter element( Do not lose the sealing ring of filter element water cap).


3. Any antifreeze can't be completely equal to purified water, do not use it all the year round or for too long time. Please clean the chiller and laser tube cooling pipe inside with purified water when the winter is over and no need to use anti-freeze product anymore. And choose desterilize purified water as the daily operation coolant.

 

If possible, we suggest to improve electricity conditions to keep the water chiller runningwith no stop. Or upgrade the cooling water path design, emptying the coolant (purified water) simple and fastfrom laser tube in everyday use.
