Cooling Water Requirements
The IBP-YAG needs a reliable flow of cooling water to dissipate the energy of the laser. The
required cooling flow is dependant on the laser power level and the initial coolant temperature.
Note: If the inlet cooling water is chilled to below the dew point, condensation will occur inside
the unit. To prevent water damage to the measurement head, purge air must be provided
DO NOT USE DE-IONIZED (DI) WATER. DI WATER
WILL QUICKLY CAUSE SEVERE CORROSION OF ALL
COMPONENTS THAT CONTACT THE WATER.
Water Pressure not to exceed 200 kPa (30 psi).
To maintain a safe working environment, do not allow the outlet water temperature to exceed
49°C (120
o
F).
