Abstract: Disclosed is a device for preservability enhancement including: a primary energy wave generation unit which generates, by receiving AC 220V power from a 220V power input unit via a noise filter, an electromagnetic field by an inner electric coil, generates a preconfigured frequency in which a generated electric field and electromagnetic field energy are included, and generates free electrons by the flow of an electric current therein resulting from the electromagnetic field; and a tertiary complex wave generation and amplification unit which receives, via an output terminal of the primary energy wave generation unit, the free electrons and the electromagnetic field having information of the primary energy wave generation unit and generated thereby and, by using the free electrons and the electromagnetic field thus received, combines, amplifies and emits the first cell-activating energy wave.
