Heat Exchangers are the best solution to heat fluids flowing in forced convection. Electrical Heat Exchangers operate in the same way as fluid/fluid heat exchanger but the hot side consists of armoured electrical heaters in direct contact with the fluid to be heated. An optimum heat exchange is obtained employing appropriate baffles whose design is tailored to exploit at best the heat released by the electrical resistances.
Thanks to the specific characteristics of the heaters, the Electrical Heat Exchangers are very compact in size and support a very precise control of the fluid outlet temperature. These systems, in fact, are characterised by a minimum thermal inertia of the hot side of the exchanger, thus providing a very fast response to the process needs and a finely controlled outlet temperature. This is especially true if SCR’s (Solid Control Relais) are employed in the control system
