Installation Requirements for the Chiller
General Information
Most laser systems generate a significant amount of heat that must be removed for proper operation. This
laser is no different. This system requires a chiller that meets the requirements shown below.
Feature
Requirement
Flow rate
9.5 lpm (2.5 gpm) required
Coolant pressure
30 psi (210 kPa)
Coolant temperature
20°C (68°F)
Coolant temperature stability
>±0.5°C
Coolant type
Nalco 460-PCCL104 (recommended) or distilled water
(4 Gallon Capacity, preferred mix is 2 Gallons of Nalco and 2 Gallons
of distilled water.)
Spectra-Physics provides optional chillers that are suitable for use with the
Quasar
laser system. If your
chiller was ordered from the factory with your laser, it meets these requirements. For specific information
about the chiller shipped with your system, consult the chiller manual included with the system.
If your chiller was not ordered from Spectra-Physics, obtain a chiller that meets these requirements. Make
sure that all wetted surfaces are either stainless steel, copper, nickel, Tygon, silicone, or Teflon. Also make
sure that the coolant is filtered through a 5 micron, pleated, absolute particle size filter prior to entering the
laser. Volumetric filters are NOT acceptable. We highly recommend that you speak with a Spectra-Physics
representative about your chiller’s design and capabilities.
