The key to the success of the lies in it’s three chamber design. Each of the three chambers; patented Bio-
drum, compost finishing drawer, and evaporation chamber, have their own independent environments for
optimum efficiency.
The Self Contained Toilet electric version has a thermostatically controlled heater and fan assembly to help
evaporate liquid and should be used where there is a constant electrical supply. The EXCEL NE (non-elec-
tric) is for use where there is no continuous electric supply. The EXCEL NE has no fan or heater. Odorless
operation is achieved by a 4” vent which acts like a chimney creating a partial vacuum within the unit.
The patented Bio-DDrum
Unique to Sun-Mar, the patented bio-drum provides the necessary mass to maintain good compost and
allows easy aeration of the compost by simply turning the drum. Excess liquid will exit through a screen in
the bottom of the drum into the evaporation chamber. Mixing the Bio-drum is accomplished by rotating the
handle in a clock-wise direction. Compost is removed from the drum by pulling out the white drum lock but-
ton (under the footrest) and rotating the handle in a counter clock-wise direction.
The Compost Finishing Drawer
The compost finishing drawer sits in an opening under the footrest. Compost in the drawer is isolated from
mixing with new waste while resting for 4 weeks so that it can finish composting.
The Evaporation Chamber
The evaporation chamber is the floor of the unit under
the compost finishing drawer. This is the area where any
excess liquid will gather for evaporation. A safety drain
exits from the back of the composting toilet which will
drain over-flow liquid that is not evaporated to an
approved facility.
