5.2. Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid used, particularly with
regard to the fire point!
If a bath fluid with a fire point of
65 °C is used, only supervised operation is
possible.
Water:
The quality of water depends on local conditions.
 Due to the high concentration of lime, hard water is not suitable for
temperature control because it leads to calcification in the bath.
 Ferrous water can cause corrosion - even on stainless steel.
 Chloric water can cause pitting corrosion.
 Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.
Recommended bath fluids:
Bath fluid Temperature range
soft/decalcified water 5 °C to 80 °C
