Excel NE

The success of the Excel design meant that a three-chamber unit could be specifically designed for those with no access to continuous 110/220 volt supply. First launched in 1981, the Excel NE has long been the standard toilet for those living off the grid. 

Listed capacities refers to the amount of people, on average, using the unit per day.
