The Z-800IIs ECO thermal control system provides a fast heat up time of 100 seconds and produces a steady, continuous fog as long as you needed it. The smoke generated is non-toxic, clean, and odorless and does not leave any residue inside the heater. In addition, the internal spiral shape heater is made of high-tech stainless steel which provides the most effective heat energy transfer. The Z-800II has a highly efficient power control system that allows the fogger to operate at low-level temperatures saving up to 20% electricity.
