fluids
Caution:
Carefully read the material 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 scale in the bath
Ferrous water can cause corrosion, even on stainless steel.
Chlorinated water can cause pitting corrosion.
Distilled water and deionized water are unsuitable. Their special
properties cause corrosion in the bath, even on stainless steel.
Recommended bath fluids:
