    Sun-Mar™ | Excel NE (Non Electric)

    Manufacturer: Sun-Mar™
    SKU: SM-EXCN-FT
    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 Product options below

    *

    Choose the fan voltage to match your power system. 

    ABS pipe (US spec) is supplied with the toilet. This is suitable for straight horizontal vent stacks.

    If you'd like to adapt the unit to NZ pipe, please select this kit. You will need NZ pipe if you're looking to create elbows and bends.

    *

    You may need additional vent materials depending on how many storeys your building has.

    Single Storey buildings with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 830mm Vent Pipe Extension

    Double Storey buildings require extra lengths of vent pipe. Please add 4 x 1m Vent Pipe Extensions.

    Double Storey building with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 830mm Vent Pipe Extension

    Kit for stepping the vent stack around the eaves of the roof. Allows you to avoid penetrating the roof.

    Add a wind-driven vent to create redundancy.
    The wind-driven vent will assist the fan under heavy wind conditions and keep the system going in case of power outage or fan failure.

    Select this reducing collar to adapt the wind-driven vent from 150mm to 100mm.

    Extend your drain pipe to reach your soak pit/trench.

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

    Most soakaways should be installed 3 meters away from the foundations of the structure but this remains circumstantial to the site.

    Run your leachate drain into a soak pit (vertical soak-away) or into a trench (horizontal soak-away).

    Designed for 2 people (full-time) and up to 6 (part-time), the Sun-Mar Excel NE is a fantastic choice for baches, sleep-outs, cabins, or any location where there is no access to a reliable power supply

    Featuring Sun-Mar's™ patented Bio-drum™ technology, the Excel is a true composting system that processes the compost in two stages within the unit itself.

    Because the Excel NE model requires no fan or heater, it is perfect for those who have no access to 240vAC power, or even a 12-volt power supply. The clever design utilizes 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 optimize airflow 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 optimize 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 its optimum level.
