Tips on Water Chiller Maintenance During Long Summer Holiday


Water cooling chiller is main accessory on laser engraving machine and laser cutting machine.  Eg CW3000 and CW5000 model is used on CO2 laser engraver while CWFL-600 is used on fiber laser cutter.  If the water cooler can not be well maintained, the CO2 laser tube, CO2 laser power supply or fiber laser on the laser cutting equipment will be easily damaged.

Summer is a holiday season. It is middle of July now and some of the European countries have already started the long summer holiday which generally lasts from July to August. How to maintain your S&A water cooling chiller in a good condition during this time? Today we will give you guys some tips.


1.  Before holiday


A.  Drain out all the cooling water from the lasercutting machine and the water chiller to prevent the cooling water from being frozen in non-working status, for that will do harm to the water cooling chiller. Even though the chiller has added anti-freezer, the cooling water should be all drained out, for most of the anti-freezers are corrosive and it is not suggested to keep them inside the water chiller for a long time.


B.  Disconnect the power of the watercooling chiller in order to avoid any accident when no one is available.


2.  After holiday


A.  Fill the chiller with certain amount of cooling water and reconnect the power.


B.  Turn on the water chiller directly if your chiller has been kept in an environment above 5℃ and the cooling water doesn’t get frozen during the holiday.


C.  However, if the water chiller has been kept in an environment below 5℃, use the warm-air blowing device to blow the internal pipe of the chiller until the frozen water defreeze and then turn on the water chiller. Or just simply wait for some time after water filling and then turn the chiller on.


D.  Please note that it might trigger flow alarm due to the slow water flow caused by the bubble in the pipe during the first-time operation after water filling. In this case, restart the water pump several times every 10-20 seconds.
