4.3 General notes regarding Trotec chillers
All chillers are delivered with Europe C19 plugs.
The coolant temperature has to be between 18 and 25°C.
If temperature falls below this range, the chiller might not be ready for operation and the coolant has
to be warmed.
4.4 Water Requirements for chiller and laser tube
Please, use normal tap water as coolant. The use of de-ionized, de-mineralized or distilled water is
not recommended and can destroy the laser tube.
Ideal water quality
Ph-value: 7-9
Alkalinity (°dH): <1
Conductivity: <300
μ
S/cm
Chloride content: <20 mg/L
Hardness (°dH): <0,1
Organic germs: <1000 KBE/ml
In case of deviations of water quality, it is recommended to us softening agents, corrosion inhibitors
or biocide additives.
