Utility Requirements and System Installation
3 - 7
Coolant Fittings
on Laser System
The DIAMOND C-20 and C-30 liquid cooled lasers have 6 mm
O.D. tubing for the connection interface. The user must supply an
appropriate compression fitting to make the connection with the rest
of the user’s system.
Cooling Capacity
The cooling system must have sufficient capacity to maintain the
coolant temperature at the outlet of the refrigerated recirculator
within the range given in Table 1-2 on page 1-5 and Table 1-3 on
page 1-6. With the laser operating at its maximum output power, the
cooling system must dissipate up to 575 W. See
Section Five: Maintenance and Troubleshooting for maintenance
and replacement requirements for the coolant.
Coolant Filtering
Coherent recommends that the user incorporate coolant filtering in
the coolant return line to avoid the accumulation of debris in the
cooling system, as shown in Figure 3-2. The filter should trap parti-
cles larger than 30 μm to 50 μm in size, unless specified otherwise
by the manufacturer of the refrigerated recirculator.
