The success of the Excel design meant that a
three-chamber unit could be specifically designed for those with NO continuous
110 volt supply. First launched in 1981, the Excel NE has long been the standard
toilet for those living off the grid. A 1998 redesign gave the unit a rounded
look, and recessed the drum handle.
The Excel NE has no fan or heater. Odourless operation
is achieved by a 4" vent mounted at the top rear of the unit which acts
like a chimney on a wood stove. For good air movement the vent should be as
close to vertical as possible.
If the Excel NE is used residentially or heavily,
or is in a place which is subject to downdraft, an optional 12 volt fan should
be installed in the vent stack. This fan draws 1.9 watts and can be powered
by a solar panel and 12 volt battery.
The fan should also be installed if there is
to be any bends in the vent stack, as the "chimney effect" is negated
by a bend.
Evaporating capacity on the Excel NE is variable,
so the 1" drain at the rear should be connected to an approved drain pit,
container, or other facility. |
