The present invention provides a novel fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, for example by way of application of Pulse Electro-Thermal Deicing/Defrosting (PETD) or equivalent technique thereto, by configuring it to increasing its resistance to a value at which the system's reactance at its working frequency is comparable to, or less than, its electrical resistance. Advantageously, the inventive system may be advantageously configured to comprise the same form factor and interface as a conventional fins-on-tubes type evaporator/heat exchanger component, such that the inventive evaporator/heat exchanger system may be readily utilized for replacement thereof.
