At higher temperatures
Only use distilled water or fully demineralized high purity water after adding 0.1 g of soda (Na
sodium carbonate)/ liter of water
Water content falls with longer operation at high temperatures
(flash point 128 °C)
− The use of acidic, aqueous bath liquid or cleaning agents (pH value < 7) is not permissible.
− With the selection of the heat transfer liquid, it should be noted that impairment of the
properties is to be expected at the lower limit of the temperature range due to increasing
viscosity. Therefore, only make maximum use of temperature ranges when essential.
− Application ranges of heat transfer liquids and hoses are general figures, which may be
restricted by the operating temperature range of the units.
With silicone rubber, silicone oils lead to substantial swelling
silicone hoses.
Safety data sheets can be ordered if required.
