Sun-Mar CENTREX 2000 High-Capacity Remote Composting Toilet System — Electric, Residential & Vacation Use
Product Description
More capacity, more flexibility, more peace of mind. The Sun-Mar CENTREX 2000 is the high-capacity electric model in the Centrex remote composting toilet lineup — engineered for properties that need reliable, year-round performance from a system that can handle real residential load. Like all Centrex systems, the composter unit installs away from the toilet in a basement, crawl space, or adjacent room, while a standard-looking 1-pint ultra-low flush toilet sits in the bathroom. The CENTREX 2000’s larger chamber supports a longer composting cycle and higher waste volumes than the 1000 series, making it equally at home in a full-time residence or a busy vacation property. With a built-in thermostat-controlled heating element, a 35W fan for odorless operation, and support for one or more flush toilets simultaneously, the CENTREX 2000 is the system for those who don’t want to compromise.
- High-Capacity Design for Residential and Vacation Use — Supports 4 adults or families of 6 for continuous residential use, and up to 7 adults or families of 9 for seasonal and vacation use — significantly higher capacity than the 1000 series.
- Longer Composting Cycle — The larger chamber allows for a longer composting cycle, improving breakdown efficiency and reducing extraction frequency compared to lower-capacity models.
- Remote Composter Design — The composting unit installs separately from the toilet, in a basement, mechanical room, or crawl space, keeping the bathroom looking completely conventional.
- Supports One or More Ultra-Low Flush Toilets — The CENTREX 2000 can serve multiple flush toilets simultaneously, making it suitable for homes or properties with more than one bathroom. Ultra-low flush toilets (1-pint) are purchased separately.
- Built-In Heating Element and Fan — A thermostat-controlled 370W heater manages liquid evaporation, and a 35W fan maintains continuous odor-free airflow through the composting chamber.
- 1″ Drain Required — A 1″ OD drain is recommended in all applications and must be connected per the guidelines in the owner’s manual.
- Versatile Installation — Suitable for cabins, cottages, homes, businesses, resorts, camps, treehouses, and workshops.
- 3-Year Parts Warranty — All Sun-Mar composting toilets are backed by a 3-year warranty on parts.
