Excel
One of the most popular Sun-Mar models to date, this high capacity bio-drum toilet is both simple to operate and reliable. As the first composting toilet model to be quality and performance certified in North America, this toilet has set the standard for the myriad of composting toilets that have followed.
With a high capacity suitable for residential use, holiday houses and in some circumstances, light commercial use, The Excel is odourless and produces clean, safe compost.
The Excel comes with a hidden vent installed at the back of the unit. This draws any odours away from the toilet itself. While the system is capable of processing all liquids through evaporation, there is an emergency drain fitted at the back of the toilet. This will need to be connected in instances of high use or in the case of power outages.
Included in the Sun-Mar Compact Composting Toilet package are:-
- Pedestal with internal Bio-drum composter
- Ventilation system including 240 volt air fan and external 2″ vent pipes with diffuser
- Liquid drain pipe
- Heater and thermostat that can be isolated via a fuse
- Starter pack containing Nature Quick Microbes (per chamber), Nature Flush concentrate with spray bottle & bulking agent (sugarcane mulch)
- Easy to follow installation and maintenance manual
Due to freight costs only gravel for the 2m long x 40cm wide x 40cm deep emergency liquid absorption trench will need to be purchased locally. Sufficient length of vent piping is supplied.
Excel NE
This is the toilet to beat when it comes to off the grid / self-sufficient living. The Excel NE was first designed in 1981 and remains the standard in completely non-electric toilets.
Ideal for those with no continuous 240 volt supply, the Excel NE remains odour free due to the diffuser at the top of the unit that draws odour away from the toilet much like a chimney draws smoke from a fire. This ventilation is aided by a 2 watt 12 volt fan that comes with a transformer to plug into mains power. The fan can also be powered by a 20 watt solar panel or 12 volt rechargeable battery, requiring only a 2 watt draw.
To ensure optimal airflow, the vent pipe (provided with the toilet) should be installed in a straight vertical line and sit 60 cm to a meter above the roof. We suggest that no more than two 45 degree angles in the vent pipe.
The evaporative capacity of this model is less than the 240 volt version which comes with a heater. This means you must attach attach the drainpipe (included) and connecting it to a sub-surface gravel absorption trench. Suggested trench size is 2m long x 40cm wide x 40cm deep. Gravel is not provided as this is more cost effective if sourced locally.
