Power supply voltage is 220 volts and 24 volts (see diagram)
It is possible to use heating elements from the table or hitblock of 3D printer or any other alternative heating elements with voltage of 220 or 24V.
The project was initially realized without temperature control using self-regulating heating cable https://github.com/pavluchenkor/iDryer and later finalized to the version with temperature control.
