1.   The first chamber is the composting Bio drum where the compost is toil kept perfectly oxygenated, moist and warm. A bulking mixture of coarse peat moss and hemp core (Compost Sure) is added to the drum to provide the necessary organic carbon to maintain the correct carbon/nitrogen balance in the compost.

2.   The second the chamber is the evaporating chamber from where the liquid is evaporated and carried up the vent stack or drained. On electric vol models, evaporation is further assisted by a thermostatically controlled heater beneath the floor of the evaporating chamber. Because air is being pulled continuously into the toilet system, a partial vacuum is maintained to help prevent any smell escaping. An overflow drain in the rear drains any excess liquid that cannot he evaporated. The user must provide a safe place for this liquid to drain.

3.   The third chamber is the compost finishing drawer, into which compost from the drum is extracted by rotating the drum in the opposite direction and the composting process is completed.

In selecting the right model, the most important questions are: [low many people will use the unit, and is electricity available? sea It is generally advised, in order to maintain a good margin of safety, to select a unit with more capacity than needed. Also, if by electricity is available all the time an electric model should he selected since they have higher evaporation capacities. Freezing temperatures will halt composting action and if temperatures surrounding the unit remain below 5O degrees F for extended periods, a small heat source should be employed with the unit to keep the composting active.

Sun Mar Self Contained Toilets
Self-contained units are installed directly in the bathroom. They are available in both electric and non-electric versions. Electric units plug into a regular three pin outlet to power a fan and a thermostatically controlled heating element in the base of the unit. The unit is normally unplugged if it is not being used for 3 days or more.  Composting capacity varies with the size of the Bio-drum. Electric units normally have more capacity than non-electric units because ar
they have extra warmth and air movement.

Although advertised composting capacities can be doubled for short periods, Sun-Mar has found that wherever possible it is always better 20 to have a good margin of safety. So. pick a unit with more capacity than you really need.

The most important advantages of self-contained units are that they need no plumbing or water Connection so they are quick and easy to install, they cost less than central units because there is no separate toilet and they are more suited to winter operations than central units, because it is often easier to keep the bathroom warm. Since the whole waste stream is recycled, approvals are not normally required. Cleaning is simple. A bowl liner beneath the seat can he removed for cleaning whenever necessary. The high quality, high gloss fiberglass finish is perfect for indoor installations.

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.
 

Sun Mar Central Composting Toilets
Central composting systems have an elegant 1 pint flush or dry toilet in the bathroom, with the composting unit installed under a building or at the side of a building. For units with I pint toilets, installation involves hooking up the water and mounting the toilet in the bathroom, connecting 3’ ABS plumbing pipe (not included) from the toilet to the composter, and erecting the 2” vent stack supplied with the unit f4’~ on non-electric units). If a Dry Toilet is used, the toilet itself must be positioned directly over the composting unit for chute installation. The Sun-Mar Dry Toilet and Sealand 1 Pint Flush toilets are purchased separately. 2 volt fans should be installed in the vent stack of all non-electric Dry toilet (A/F) units, with all AC/DC units, and with the non- electric version of the Centrex 3000. 12 Volt fans are optional with all non-electric Central units. With a flush toilet, evaporating all liquids can be difficult. An~ excess liquid is able to drain out of the overflow drains which should always be hooked up to a collecting tank or art approved handling facility.

Centrex 1000
The Centrex 1000 model is ideal for light seasonal use. lii light to medium seasonal use the 1000 is typically able to hold compost far the tell season, and compost needs extraction only in the Spring. The AC model use a maximum of 3.6 kilowatt hours per day and is suitable far use by 5 to 7 people. The non-electric (NE) model is suitable for use by 4 to 6 people. The AC/DC model can be used where some AC power is available but DC power is available to run a fan all of the time.

Centrex 2000 and Centrex 3000
Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle and larger waste volumes than the 1000 models. The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units. When used seasonally by up to 7-9 adults, compost will normally only need removing annually each spring. In residential use compost will have to be extracted more frequently. When used residentially by up to 4 adults, some compost will need to be emptied into the finishing drawer once every few months. The Centrex 2000 AC model features a 370 watt thermostatically controlled heater in a sealed compartment under the unit and the standard Sun-Mar 30 watt turbo fan, with a 2” vent stack to remove evaporating liquid and fresh odors. The NE model is suitable for 3 5 people in continuous use. Units are available for 1 pint and dry toilets.

The Centrex 3000 NE (Non-Electric) employs a continuous flow design for very heavy cottage or medium residential use. Rotation of the drum moves compost along the larger and longer 3000 series drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions the drum will not have to he turned backwards for emptying. When used seasonally by up to 10 adults, compost will normally only need to he removed from the collection chamber annually at the beginning of the following season.
