How the Sun-Mar Mobile™ Works
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 fitted with a gasket 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 footrest 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 Mobile uses only a 12-volt 4-watt fan which vents via a 3-inch pipe. The fans are installed in boxes together with zeolite and carbon filters to eliminate odours at deck or roof level. The fan is connected to a vertically mounted vent pipe. A deck or roof vent is not supplied but should be installed such that water is prevented from entering the system. Solar vents are very affordable and effective since they can take over the job of the 12-volt fan during the daylight hours.
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.
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 odours. This has proven successful, and ensure odour-free operation at deck level.
Evaporation and Electrical Configuration
- The mobile has a 12 volt 160 watt (80-watt average) thermostatically controlled heater
Evaporation is aided by this heater that is located in the sealed base compartment.
There should be enough 12 Volt battery power to keep the 12 Volt 4.0 Watt fan running continuously, and it can hooks up on a separate circuit from the heating system to facilitate this; the overflow is drain required when this is done.
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.
