Units - Why?
Self-contained units are
installed directly in the bathroom. They are available in both
electric and non-electric versions.
Electric units plug into a
regular three pin outlet to power a fan and a thermostatically
controlled heating element in the base of the unit. The unit is
normally unplugged if it is not being used for 10 days or more.
Composting capacity varies with
the size of the Bio-drum. Electric units normally have more
capacity than non-electric units because they have extra warmth
and air movement.
Although advertised composting
capacities can be doubled for short periods, Sun-Mar has found
that wherever possible it is always better to have a good margin
of safety. So, pick a unit with more capacity than you really
The most important advantages of
self-contained units are:
- Being waterless, they need no
plumbing or water connection. This means they are quick and
easy to install since the only task is to assemble the vent
stack which comes with the unit.
- They are more economical than
central units because there is no separate toilet.
- They are more suited to winter
operations than central units, because it is often easier to
keep the bathroom warm.
- Most units normally evaporate
all liquids in seasonal operation. Since the whole waste
stream is recycled, approvals are not normally required.
- Cleaning is simple. All
self-contained units have a bowl liner beneath the seat, which
can be removed for cleaning whenever necessary.
- High quality, high gloss
fibreglass finish is perfect for indoor installations.
