Specifications

The Ecolet family of composting units are the first composting
toilets specifically designed to recycle waste on boats and
recreational vehicles. Less pump-outs! No more chemical toilets!
Recycling brings freedom, with the ODOR-FREE operation of a
Sun-Mar.
The Design of the Ecolet Family
Although the Ecolet uses Sun-Mar's tried and true three-chamber system,
"marinizing" the unit led to some interesting adaptations. The need to be
able to handle violent motion meant that the finishing drawer had to be
gasketed so that no liquid could escape from the evaporating chamber.
The air intakes faced the same problem. These had to be located higher
up and the air ducted down to the evaporating chamber.
At the same time, a new drum lock was designed to ensure that the
composting drum was held upright under all sea conditions.
Space constraints meant that a fold-away foot rest was needed on the
unit. This footrest had spring loaded legs, and a safety release
mechanism to enable it to be removed periodically when access to the
finishing drawer was required.
To assist installation, strong mounting brackets were mounted at the
base and rear of the unit. The only difference between the ECOLET
(Sloped back) and the ECOLET (Regular) is that the MARINE unit had a
45° angle designed into the base of the unit at the rear, so that hull
shapes could be better accommodated when the ECOLET was mounted
across the boat rather than fore and aft. The RV unit has a square bottom
for easier installation in a vehicle. The RV unit is also ideal for a boat
where the installation does not require the 45° angle at the back.
Electrically, the ECOLET Family are quite different from other units
because of the unique situation on many boats and RV's. A 4.0 Watt 12
Volt fan is installed in a fan box within the vent stack. This fan, (which is
on its own circuit) is designed to operate continuously while the unit is in
use.
To assist the 12 Volt fan in providing adequate venting, the ECOLET is
unique among Sun-Mar units in having a 3" vent stack. Customers need
to supply their own deck vents, which should be constructed to allow
adequate air movement while preventing seawater from entering the
unit.
Carbon and Zeolite Filter
While venting is optimal above deck level, some installations will require
that the deck vent is flush with the deck. Sun-Mar has incorporated the
use of activated carbon and zeolite filter materials in the fan box to
"scrub" the air of fresh ammonia odors. Tests of this have proven
successful, and ensure odor-free operation at deck level.
Dual Voltage Heater Configuration
Evaporation is aided by separate 12 Volt and 110 volt heaters each of
120 Watts, and both with their own individual thermostats. These heaters
are located in the sealed base compartment which on the Ecolet (Sloped
Back) also extends up the 45° angle at the rear of the unit.
The thinking in designing two different heaters into the unit was that a 12
Volt supply is often available while the unit is in motion, while the 110
Ecolet Unit Selection
Will you be using the unit in a marine
vessel with limited 12 Volt Power, and
require the shape of the unit to
conform to a 45° hull? If so, choose our
ECOLET (Sloped Back)
Will you be using the unit in a trailer or
recreational vehicle or a fore to aft
marine installation? If so, choose our
ECOLET (Regular). (See below for
details on all units)
Do you have a 12 Volt power source
that can handle a 10 amp heating
system? If so, choose our dual voltage
option for either unit, for added
evaporative performance
