Long considered the standard in composting
toilet performance, the EXCEL is the preferred self-contained
electric model for heavy or residential use.
Composting speed and capacity on this unit is outstanding!
The large Bio-drum engineered into the Excel gives it twice
the capacity of the Compact.
The Excel has been successfully tested by the National Sanitation
Foundation for six continuous months at its maximum residential
capacity of four adults. Key criteria were that the unit operated
odorlessly, and produced a clean dry compost.
For weekend and vacation use the capacity is 6-8 people, and
even these numbers can be doubled for short periods.
For comfort, the Excel has a detachable footrest which can
be removed to pull out the finishing drawer.
Although the Excel can normally evaporate all liquids, a
½" emergency drain is fitted at the rear and this should
be connected if heavy use or prolonged power outages are expected.
