Sun-Mar Centrex toilets are designed with a central composting unit, and a separate toilet bowl. They’re easiest to use in a cabin or home where the toilet and composter can be installed on separate floors, so the toilet has sufficient clearance for the waste pipe to easily empty into the composting chamber. Unlike self-contained composting toilets, Centrex systems allow you to locate the composter outside the living area of your home, allowing you to use a more “normal” looking toilet unit.
About this model:
Designed for medium to heavy year-round use, the Centrex 3000 allows for both a longer composting cycle, and higher volume than the 2000 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 9 adults (or a family of 11), 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 6 adults, or a family of 8, some compost will need to be emptied into the finishing drawer once every few months.
All Centrex 3000 electric units feature a 370 watt 120 volt thermostatically controlled heater in a sealed compartment beneath the unit coupled with the standard Sun-Mar 30 watt turbo fan and 2″ vent stack.
- AC/DC kit available to enable use with 12V DC.
- The Centrex 3000 is supplied with a 1″ drain hose which should be connected to the 1″ drain at the bottom of the unit. See Sun-Mar for more information on handling excess liquid.
- The Centrex 3000 is used with one or more 1 Pint Flush toilets.
- Add a 13″ or 17″ toilet bowl to complete the Centrex 3000 kit.
