Oils of the series Diatherm show an excellent thermal stability and a very high resistance to oxidation; thanks to this feature they can be used for long periods of time at high temperatures. A high thermal conductivity and a low viscosity provide a heat transfer at high speeds and with low energy consumption of water pumping.
Furthermore, they protect the iron and copper components from rust and corrosion. In this way the air trapping which causes the unpleasant foaming phenomenon can be avoided.
The operator’s check must guarantee a proper plant maintenance and a regular drainage of the same to prevent that the oil is subject to moisture contamination. Please remember that the temperature of the oil surface in contact with air must never exceed 105°C.
