At higher temperatures vaporisation losses occur. In this case use a bath cover (

The proportion of water reduces with longer working at high temperatures and the mixture be-
comes flammable (flash point 128 °C). Check the mixing ratio using a hydrometer.
Do not use in conjunction with EPDM hose.
−
When choosing the heat transfer liquid, it must be noted that at the lower limit of the operating
temperature range a worsening of the tempering properties is to be expected due to the in-
creasing viscosity. Therefore, only use the full operating temperature ranges where neces-
sary.
−
The working ranges of the heat carrier liquids and hoses are general figures which can be
tightened due to the operating temperature range of the devices.
−
Do not use any contaminated heat transfer liquids. Contamination of the pump chamber may
lead to the pump jamming and the device then switching off.
−
Never use silicone oil with silicone hoses.
Safety data sheets can be ordered on request.
