| 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.
The 2"
vent is attached at the top rear of the unit and can be installed invisibly
by running it through the wall and up the outside wall. 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 the unit is
to be used residentially or heavily, or if prolonged power outages are
expected.
