 Water Cooling
FiberMINI
®
AF processing heads are
equipped with a water-cooling circuit.
 Water-cooling is the recommendation
when power levels exceed 1kW.
 Power level should never exceed
4kW.
 See Figure 3 for location and hose
size. See the table below for
recommended specifications.
The design intent of the cooling circuit is to
operate on a closed-looped cooling
system or facility tap water – as long as it
meets the requirements in the table below.
Minimum Flow Rate
1.5 liter/minute @ 2 BAR min
Inlet Pressure
5.0 Bar (72.5 psi) Max
Inlet Temperature
≥room temperature / >dew point
Hardness
(Equivalent to
CaCO

)
<250mg/liter
pH
6 to 8
Particulate Size
<200 microns in diameter
 Assist Gas
See Figure 3 for location and hose size.
 Maximum pressure is 20 BAR.
Impurities in the assist gas such as
hydrocarbons (THC) and moisture (H
2
O)
can damage optics, cause power
fluctuations and result in inconsistent cuts.
See the table below for recommended
assist gas specifications.
