The Centrex 3000 NE (Non Electric) - A/F (Air Flow) is a high capacity, low voltage, waterless “off-grid” alternative to the straight Centrex 3000 (heated) models. The system is designed for use in conjunction with a waterless toilet pedestal and processes waste under the bathroom floor, the non-electric system is slightly smaller than its electric counterpart.
With a larger compost capacity than the Centrex 2000 A/F NE model, the 3000 NE - A/F can comfortably accommodate up to 7 people in a holiday house situation. In a residential capacity, the compost needs to be emptied more frequently and is suitable for up to 5 people.
There is no heating unit in this model so it will operate beautifully on solar or mains power. Without the heater the evaporation process is not as effective as in the 240 volt system. Therefore an overflow drain to a small sub-surface gravel pit is required (200x40x40cm).
A 100 mm vent and low voltage fan help to ensure that odours are dispelled with minimal electrical draw.
Listed capacities refer to the amount of people, on average, using the unit per day. Do not pick a unit that is below your capacity.
