1. Model selection: laser heating value is calculated according to photoelectric conversion efficiency of the laser
Calculation formula: P (Heat) = P (Laser) ·(1-η)/η
P (Heat): Heating value of the laser (W)
P (Laser): Laser input power (W)
η: photoelectric conversion efficiency of the laser (%), depending on different lasers
Value range of carbon dioxide lasers: 8％-10％
Value range of solid-state lasers: 2％-3％
Value range of semi-conductor lasers: 20％-30％
Value range of fiber lasers: 20％-30％
e.g.: For a carbon dioxide laser, the output power is 2000W and photoelectric conversion efficiency is 8.5%, then heating value can be calculated as:
P(Heat)＝2000 x（1-8.5％）÷8.5％＝2000x10.8 ＝21530W
Cooling capacity of water chiller should be greater than the laser heating power. As a result, you can select MCWL-250DT.

Note: Water chiller for laser should be used in a well-ventilated place without dust and corrosive gas. Do not place any sundries around the chiller.
