Abstract
Improvements in thermo-pulsing devices, essentially characterized by having an electric fan inside a housing and facing it a set of electrical resistances, arranged in a circle around the fan, the apparatus comprising a rear window for air intake and a window previous to its output, and presenting the housing, on its back a control box, which includes a switch for the stop and start-up of the set of resistors and fan, or a switch for the joint running of resistors and fan or fan only according to the position, for the use of the device as an impeller only.
