Summary. We give one of the possible technical solutions for remote control of heat transfer in the bioreactor at resonant levels by ultrasound beam. Outlines the conditions of coincidence wave, which is accompanied by a sharp increase of energy activity, along with a minimum dissipation of radiation waves. Explained the nature of the additional energy activity in areas of caustic surfaces with two types of waves.

Keywords: bioreactor, energy activity, wave coincidence, cavitation, cutoff frequency.
