Low-flow, traditional, small-to-large capacity, base unit for composting toilet
For those that want a traditional-looking toilet in the bathroom, Centrex family low flush systems are ideal. The base unit is installed out of sight. All you see is the Sealand one-pint flush toilet, purchased separately as an accessory in white or bone.
The Sealand in the bathroom is connected by a standard 3" plumbing pipe to the Centrex composting unit below the toilet in the basement or crawl space, normally within 15-20 feet.
Composting toilets use the natural process of decomposition to break down waste into usable nutrient-rich top soil. To begin the process, add microbes to the drum. As waste continues to enter the toilet, the drum must be turned at least every two to three days.
Solid waste must always be followed by a scoop of bulking material. When the toilet is half-full, the finishing process begins. Thirty days later, there's usable odor-free compost.
Electric (E) - Standard Model: For those with continuous 12v power, an electric unit is suggested. Electric units feature a 370w 120v thermostatically-controlled heater in a sealed compartment beneath the unit. Odor-free operation is maintained by a standard 30w turbo fan directing air up a 2" vent stack.
Non-Electric (NE): If you have no electricity, then a non-electric (NE) unit is the right selection. A 12v fan is supplied with Centrex 2000 and Centrex 3000 series for battery/solar hook-up, non-electric units, but are not normally needed for cottage applications unless the system is used heavily or is particularly subject to downdraft.
AC/DC units: are dual vented units with both a 2" and 4" vent for those who expect to have 110v power in the future, or are running a generator for 12 or more hours per day.
Batch unit (Centrex 1000, 2000): Batch composting means that the catchment receptacle is filled, removed, and allowed to decompose and cure without the addition of more waste. Thus, a toilet using a batch composting process typically requires more than one catchment chamber (i.e. composting reactor).
Continuous unit (Centrex 3000): Continuous composting means that the catchment receptacle is constantly receiving new waste materials, while at the same time producing finished product. A toilet using a continuous-composting process usually requires only one catchment chamber.
Central Flush unit sizes
The selection of the base unit should be based on both whether the unit is used seasonally or residentially, and the number of people that will be using the unit.
Centrex 1000 (batch unit) - suitable for light to medium cottage use
Centrex 2000 (batch unit) - suitable for medium to heavy cottage use or light residential use
Centrex 3000 (continuous unit) - suitable for very heavy cottage use, or medium residential use
