tubular heat exchanger / liquid/liquid / stainless steel / corrosion-resistant
Max.: 40 °C (104 °F)
Min.: 0 °C (32 °F)
The combined heat exchangers combine the advantages of tubular heat exchangers and electrical heating. If the heating fluid is not yet available (e.g. boiler fired by heavy oil), electrical preheating is effected. The tubular heating surface transfers the thermal energy of one medium to the other. The fluids involved are mainly liquid but can also be gaseous. The type and properties of the fluids, pressures and temperatures as well as the desired operating points in the process are important for the design.
One fluid in the combined heat exchangers dissipates the energy, and this energy is transferred through a pipe wall to the other fluid. Here, it is important that the design be matched to the general conditions, for each fluid has its specific properties.
