Medium composting toilet systems
EcoLet™ composting toilets for homes, baches and off-grid living
EcoLet™ uses modern technology to accelerate and optimise natural biological decomposition, evaporate excess liquid and exhaust odours and water vapour.
The EcoLet™ system uses fan-assisted ventilation, mixing arms and controlled heat to support the composting process inside an attractive home-style appliance that is easy to use and economical to operate.
Moist air is carried away through the ventilation pipe, while the mixing system aerates the compost and helps sift finished material into the humus tray. Adjustable heat settings and recirculation of heated air help manage moisture with low energy use.
The humus collection tray is emptied periodically depending on usage, and additional humus starter or approved bulking material is added as required to maintain a balanced composting mix.
Best suited for: homes, baches, cabins, small off-grid properties and medium residential composting toilet applications.
- Modern self-contained composting toilet format.
- Fan, heating and mixing functions support biological processing and moisture control.
- Designed for indoor bathroom-style installations where ventilation and setup requirements can be met.
- Practical option for customers wanting an electrically assisted composting toilet system.
