liquid heater / immersion / electric / convection
Screw-in heaters are designed for efficiently heating liquid or gaseous fluids which are flowing or stagnant. The design is based on the general conditions such as the type and properties of the respective fluid, pressure and temperature as well as the desired operating points in the process.
Screw-in heaters directly heat fluids, converting electrical energy in the heating rods to thermal energy. The thermal energy is then transferred from the heating rods to the fluid. Here, it is important that the design be matched to the general conditions, for each fluid has its specific properties.
