Composting Toilet Systems: Excel AC/DC M

The Excel AC/DC M waterless composting toilet is specifically designed for use in boats and mobile homes. It has all the features of a standard Excel plus a few additional ones to make it mobile. The Excel AC/DC M can handle 3 - 4 people in full time use or up to 8 people on a part-time basis. The Excel AC/DC M waterless toilet has a unique three chamber processing system including the patented Bio-drum. It is a stand alone single unit composting toilet with a high gloss white casing. The Excel AC/DC M waterless composting toilet is superior to competing self-contained products because it uses a rotating drum to mix and aerate the waste rather than a mixing bar or rake. The drum ensures optimum composting by providing the best composting conditions. The waste falls into the Bio-drum where it is mixed and composted for approximately 2-3 months. After this time some of the material is released into the finishing tray where it sits for a further month sealed from any fresh material to complete the composting process.

Like the standard Excel, the Excel AC/DC M waterless composting toilet comes with a 230 Volt heater and fan to improve the composting conditions. A 12 Volt fan with a filter is also included to remove odours via a 4” vent pipe. The fan filter consists of activated carbon and zeolite materials which “scrub” the air of fresh ammonia odours ensuring odour-free operation at deck level. Along with speeding up the composting process and removing odours, the fan and 230 Volt heater act to evaporate all of the liquid waste produced. However, when disconnected from 230 Volt power it may be necessary to connect the system to a small container or small holding tank to collect any liquid waste that fails to evaporate.

Due to possible violent motion at sea or on the road, the finishing drawer of the Excel AC/DC M waterless toilet has been gasketed to ensure that no liquid can escape from the evaporating chamber. The air intakes have also been located higher up and ducted down to the evapourating chamber. Strong mounting brackets have also been fixed to the system to ensure that the toilet is firmly fixed to the floor and won’t tip over in rough conditions. A drum lock keeps the composting drum upright under all sea/road conditions.

The advantages of using a waterless composting toilet in a mobile situation are:
• No need to carry water for the toilet which results in reduced fuel costs.
• No need to carry large quantities of black water.
• No need to hunt for discharge stations.
• Increased self sufficiency and freedom.
• No chemicals or odours.
