I have two lasers, I never operate them at the same time. One is connected to a proper chiller unit, while the other is connected to a CW-3000, which can only cool down to the surrounding air. I was wondering if it would be possible to connect both lasers to the same chiller, so the water goes from the chiller through one laser tube, then to the next before returning to the the chiller. Would lower my running costs as I run both units 24/7 even though I'm not operating the lasers on anything like that.
