At higher temperatures ! Evaporation losses ! Use bath covers (
Distilled water or fully deionised water must only be used with the addition of 0,1g sodium
carbonate/l water, otherwise
! danger of corrosion!
Water content falls after prolonged operation at higher temperatures
! mixture becomes flammable (flash point 128 °C).
! Check the mixture ratio with a densiometer.
− When selecting bath liquids it should be noted that performance must be expected to worsen
at the lower limit of the operating temperature range due to increasing viscosity. The full
operating range should only be utilised if really necessary.
− The operating ranges of the bath liquids and tubing represent general data which may be
limited by the operating temperature range of the unit.
