The Sun-Mar Mobile 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 Sun-Mar Mobile Family
Although the Sun-Mar Mobile 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 has to be gasketed so that no liquid can escape
from the evaporating chamber.
The air intakes face the same problem. These have
to be located
higher up and the air ducted down to the evaporating chamber.
At the same time, a special drum locker ensures
that the composting
drum is held upright under all sea or road conditions.
Space constraints mean that a fold-away foot rest
is needed on the
unit. This footrest has spring loaded legs, and a safety release
mechanism to enable it to be removed periodically when access to the
finishing drawer is required.
To assist installation, strong mounting brackets
are mounted at the
base and rear of the unit. The only difference between the Sun-Mar
Mobile (Sloped back) and the Sun-Mar Mobile (Regular) is that the
Sloped Back unit has a 45° angle designed into the base of the unit
at the rear, so that hull shape could be better accommodated when the
Sun-Mar Mobile was mounted across the boat rather than fore and aft.
The Regular unit has a square bottom for easier installation in a
vehicle. The Regular unit is also ideal for a boat where the
installation does not require the 45° angle at the back.
Electrically, the Sun-Mar Mobile 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 Sun-Mar
Mobile 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.
Evaporation and Electrical Configuration
Evaporation is aided by a 110 volt, 120 Watt
heater and thermostat.
This heater is located in the sealed base compartment which on the
Sun-Mar Mobile (Sloped Back) also extends up the 45° angle at the
rear of the unit.
The thinking in designing a 110 volt heater into
the unit was that a
12 Volt supply is often available while the unit is in motion, while
the 110 volt heater can frequently be used while the vehicle was in an
RV park, or, in the case of a vessel, hooked up to shore supply.
There should be enough 12 Volt
battery power to keep
the 12 Volt 4.0 Watt fan running continuously, and it hooks up on a
separate circuit to facilitate this.
Optional 12 Volt Heater
Most do not have enough 12 Volt power to run a 120
watt heater at 12
Volts when it is on - for that reason the 12 Volt Heater is available
as a special option only, and all of the units will come with just the
110 heater when ordered. If you order the unit with the optional 12
Volt heater, it comes with both a 12 Volt and 110 volt heater in the
base, allowing you to use the 12 Volt heater at sea or on the road, and
to conserve your power by using the 110 volt heater at shore or while
parked.
Overflow Drain Required
Evaporation capacity on Sun-Mar Mobile units is limited by the size of
the heater, the surface area of the evaporation chamber, and the volume
of air movement. Consequently, arrangements should be made to connect
the Sun-Mar Mobile drains to a container or small holding tank for
disposal in an approved manner, especially if you are unable to
incorporate the 12 Volt heater option into the unit.
Sun-Mar Mobile 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 Sun-Mar Mobile (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 Sun-Mar Mobile (Regular).
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
