Evaporation losses
Use bath covers.
Only use distilled water or fully demineralized high purity water after adding 0.1 g of soda
(Na

sodium carbonate) / liter of water,
Risk of corrosion!
Water content falls with longer operation at high temperatures
Mixture becomes flammable
(flash point 119 °C).
Check the mixture ratio with a hydrometer.
At devices with nickel-plated evaporator (RP 845, RP 855, RP 890, RP 1290 and RP 1845)
you must not use acid, aqueous heat transfer liquids resp. detergents (ph-value < 7).
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. Never use silicone oil with
silicone hoses.
Safety data sheets can be ordered if required.
