The innovation belongs to equipment for adding useful properties to liquids. The equipment contains wireframe pyramids with ribbings, chambers for activation made in the form of truncated cones with induction coils on side surfaces, separated by the cone made of dielectric material located in a metal case covered with a lid. Receiving antennas, connected to a node with induction coils of cones, are fixed in the isolating equipment. Each chamber is placed in a pyramid, and the chambers are connected to each other by docking unit with horizontal antenna and induction coils. Hoses for liquid passage are placed in the docking unit in spiral tiers. The technical result is the increase of the degree of liquid medium activation.
