Optimizing machine-tool efficiency – with FUNKE electrical oil pre-heaters
Using electrical oil pre-heaters is of high importance for assuring ideal machine-tool efficiency, minimization of energy consumption and wear protection.
FUNKE offers a highly developed modular program with 11 sizes for the typical requirements of mechanical- and plant engineering with a heating power of 3 to 100 kW.
Applications heating of oil, flame resistant liquids and emulsions by electrical energy, especially for machines and facilities outdoors and on test stands which require selected oil temperatures.
Function
The medium to be heated flows around a bundle of u-shaped bent heating rods. The distance of the switching segments guarantees an adequate flow velocity, even at the allowed minimum flow rate. The standard heat transfer per unit surface area is approx. 2 W/cm².
The surface temperature of the heating rod is only 110°C at minimum flow rate and at oil inlet temperature of 60°C. Thus, the temperature is far below the coking temperature of oil.
The temperature limiter installed cuts off at 80°C.
