Laser Engraver Forum

I've recently purchased a CO2 80w laser from china.

I purchased the CW-3000 "chiller" as it seemed to be highly recommended by folks that I spoke to but after using it for a few days, I've discovered that it totally useless to me for use in sub-tropical Brisbane in summer. I couldn't work out why it always gets to approximately ambient temperature after a short period of use so I opened up the case to trouble shoot. I discovered that the "chiller" is not a chiller at all but it's just a glorified water pump.

To keep myself operational, I'm going to use ice to help with the cooling but I need a long term solution.

I would like to hear from others who live in warm climates about how you cool your laser.

Thanks
Johno

Fatbody tubes really need to be kept under 23 degrees Johno but normal tubes are fine up to 28 or so. Better would be a nice stable temperature between 17 and 19C

Too low can cause condensation problems , too high will lead to early tube failure. The best temperature and the best for us temperature are two different things by about 250 degrees

Thanks for your helps guys.

I've purchased an aquarium chiller that was old stock at the local supplier so was discounted.

I have put it in series between the CW-3000 and the laser tube. I'll be testing it tomorrow but I don't expect any problems. The pump on the CW-3000 is rated at 15 litres per minute (800 per hour) and the chiller is rated at 800-2200 litres per hour and is adjustable for temperature between 0 and 40 deg C.

I'm not sure what the ideal temperature is for the laser tube is but I figure I'll start at 15 deg C and go from there. If anyone has any guidance regarding the best temperature I'd love to from you.
