The flow rate should be chosen so that the temperature difference between
the inlet and outlet of the chiller becomes less than 3°C. The customer can
refer to the following table.
Type Flow rate
C1500B 50 liter/min
C2000B, C2000C 75 liter/min
C3000C, C3000D 120 liter/min
C4000A 160 liter/min
C6000B 250 liter/min
The cooling water from chiller is temperature–regulated.
D Choose the tubing material which can withstand corrosion, which will
choke the water flow.
D Make the hose length between the laser and chiller as short as possible.
Along hose makes the pressure 1oss high and becomes a burden to the
chiller pump.
D Place a strainer at the water inlet of laser. It will prevent the f1owing
in of the dust into the laser.
D Place flow meters both at the inlet and outlet of the laser. Daily
checking of the water f1ow contributes to the prevention of abrupt stop
of laser operation.
The water fittings of the inlet and outlet of lasers are shown below.
