Yes, you can, but have to know the 2 hots and the neutral/ground. It would be rather simple to wire up a wall socket for it next to the dryer outlet. (Note; will not be up to code.) What 'unit" are you trying to power?
@DanStanton: BBC black body Little Buddy conveyor dryer for screen printing. The belt motor is 110 no problem. Heating panel is 230 with the nema 6-20p plug.
