If operating a 130watt (150w peak) Chinese laser out in a warehouse with no a/c and 100 degree summers with moderate to high humidity what chiller would you choose and why? I'm like to keep the water temp around 16-17 degrees Celsius if possible. Would the CW 5200 chiller work during those hot 100 degree days, or would it be better to go with the CW 6000 chiller?

5200 has a 1,400 watt capacity Keith :) even if the tube is 10% efficient you will still be inside a safe margin unless you plan on engraving all day with a 130 watt tube

the 6000 is a 3kW so will be working less hard to keep temps down

I am planning to run jobs all day with the 130w tube. Cutting mainly, some engraving.

Dave, are there any issues with taking the tube from 35+C down to say 19C every morning and then letting it warm back up overnight, day after day?

Not that I know of or have data for John, that said I tend to run all my chillers 24/7 to keep a nice stable temperature going through them constantly.

Thermal shock is never a good thing but the chillers cool quite slowly so not too much of an issue in day to day running that I have any experiences of

You say Moderate to High Humidity........

You won't be able to run that low of a temp without flooding your laser with condensation.
Where I live in FL I can't run mine lower then 21-22*C in the summer. Right now I'm able to get it down to 19-20 without any condensation.

To clarify Dave are you saying that if we cut and engrave all day that 5200 won't be enough, that it's only enough if you use the laser infrequently?
