Composting Toilets & Garden Composters

The Excel is not only our
best-selling unit, but also the first self-contained composting
toilet to be certified by NSF (National Sanitation Foundation) in
1989. Since then, we have made many modifications to improve
performance in all three chambers - evaporation, composting, and
finishing. When you purchase an Excel, you are purchasing the
composting toilet that sets the standard.
The Excel is ideal for residential use having been tested by NSF
with 4 adults using the unit residentially for six months of
continual use. In this test, the criteria were that the unit
operated odorlessly and produced clean, safe compost. Of course, it
did, and the Excel is presently the ONLY self-contained unit in the
world to be tested, certified, and listed by NSF.
The Excel is also ideal for
cottage use as the primary toilet at your camp or cabin, or for
light commercial or workplace use. The 2" vent is attached at the
top back 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 sturdy 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. |

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.
Odorless 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 installed vertically and to
2-3 feet above the peak of the roof.
The
optional 12 Volt Fan
should be installed if you need to install the toilet with any
bends in the vent. No more than 2 45° bends are encouraged, even
with the fan.
If the Excel NE is used residentially
or heavily, or is in a place which is subject to downdraft, the
optional
12 volt fan
should be installed in the vent stack. This fan draws 1.4 watts
and can be powered by a solar panel and 12 volt marine battery.
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

The Centrex 1000 model is ideal for those
who have electricity and want a unit for a light seasonal
application.
All central units, including
the Centrex 1000 series, are fitted with a removable evaporating
tray under the drum screen in the evaporating chamber. This tray
helps to trap any peat moss debris, and provides an extra
evaporating surface.
In light to medium seasonal
use the Centrex 1000 is typically able to hold compost for the full
season, and compost needs extraction only in the Spring.
The Centrex 1000 features a
260 watt heater in a sealed compartment under the unit and the
standard Sun-Mar 25 watt turbo fan and 2" vent stack to ensure
odorless operation.
All 1000 series units are
supplied with a 1" drain hose which should be connected to the 1"
drain at the bottom left of the unit.
