Water Cooled Laser Connections
The 1625 laser requires water cooling connections.
The rear plate of this laser is pictured below:
Connections to IN and OUT require polyethylene tubing of ½ inch outside diameter that
is capable of handling pressure of up to 60 psi (4 bar). The internal cooling components
of the laser are rated at 60 psi.
The following materials are used in the cooling path of the laser:
Delrin
®
Copper
Viton
®
rubber
The recommended coolant is water. Additives should be used to control corrosion and
algae as recommended by the manufacture of the chiller. Use high quality water such
as distilled or deionized water to avoid scale buildup. Keep the concentration of water
at above 90% relative to additives to maximize the specific heat of the coolant.
• Maintain the coolant pH above 7 to avoid damage to the copper cooling pipes.
• Never use tap water cooling. The mineral content, temperature or pH may cause
damage.
• Never allow condensation to form on the laser.
• If condensation forms, DO NOT operate the laser until it’s dry again.
• If any water leaks are detected at the laser, SHUT DOWN IMMEDIATELY!
• Incorrect flow direction will cause a system fault.
• A water filter must be in line with the IN connection.
