FIELD: transport engineering.
SUBSTANCE: invention relates to transportation and discharge of products in cold and viscous state, for instance, oil and oil products, and it can be used for accelerated emptying of railway tanks and other shipment containers. Inductive device for warming and draining products in cold and viscous state from tank contains semiconductor frequency converter 1, and inductor 2 made in form of hollow non-closed cylinder placed on drain device 3. Moreover, device is furnished with other inductors whose form follows form of tank walls in lower and middle parts.
EFFECT: intensification of product drain process, reduced consumption of power owing to automation of selection of operation modes depending on ambient temperature and temperature of product in tank.
