The original composting toilet for Mobile and Marine applications, no muss and no fuss, no changing containers, no pouring out urine. Self-contained and with a little maintenance works like a charm! The Sun-Mar Mobile was the first composting toilet 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.
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 had to be gasketed so that no liquid could 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. Electrically, the Sun-Mar Mobile units 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.
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. This has proven successful, and ensure odor-free operation at deck level.
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.
Seasonal capacity: 3 adults
Residential use: 1 adult.
