Laser Engraver Forum

Hi all, I have a refrigeration unit KOOLANT KOOLERS a 2HP water pump, which is the PSI you have to have laser system? (AMADA LC1212 AII - year1995 - C1500B)
Now that value was 30PSI right?

I await answers greetings to my friends!

Water pressure should be between 4 and 5 bar (60 to 70 psi). More important, the water flow for a 1500B should be 50l/min (13.2 gal/min). That is for the resonator only; you'll need some additional cooling flow for the machine side (external optics, lens).
