    Sun-Mar™ | Excel NE (Non Electric)

    Manufacturer: Sun-Mar™
    If you’re in a situation where you need to be off-the-grid and completely self-sufficient, then this is the Sun-Mar model you want to look at. The Excel NE model was first designed in 1981 and still today it remains the standard setting unit for completely non-electric composting toilets.

    Choose the fan voltage to match your power system. 

    The system is packed with 1 meter of 25mm leachate drain pipe as a standard. 

    Most soakaway's should be installed 3 meters away from the foundations of the structure but remains circumstantial to the site.

    Designed for 2 people (full time) and up to 7 (part time), the Sun-Mar Excel NE is a fantastic choice for batches, sleep-outs, cabins or any location where there is no access to a reliable power supply

    Because the Excel NE model requires no fan or heater, it is perfect for those who have no access to 240, or even 12 volt power supply. The clever design utilises a diffusor at the top of the unit which draws away any odour from the toilet in much the same way that a chimney draws smoke from a fire.
    The systems pipe should be installed in a straight vertical line in order to optimise air-flow, and sit at least 600 - 1000mm above the roof.
    If the toilet is to be used full time in a home, if there are bends in the pipe or if the location of the toilet is especially predisposed to downdrafts, it is recommended that an optional 12v, 1.9watt fan be installed to help optimise performance and reduce the likelihood of any odour. If required, this 12v fan can easily be powered through a simple solar set-up. Waterless Composting Toilets NZ offers cost effective solar solutions to complement this model if required.
    As this system has no heating pads, the included drainpipe must be installed to help the system cope with any excess moisture build-up in the chamber and ensure that the unit is still able to function at it’s optimum level.
