Excel Series

The Excel is the best-selling unit in North America and for good reason. It is a high capacity Bio-drum toilet that is very simple to operate, features well proven technology and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are literally purchasing a composting toilet that sets the standard.

The Excel has enough capacity that it can be used just about anywhere: in residences, cottages and even in light commercial applications.

To simulate residential use the Excel was tested by the National Sanitation Foundation (NSF) at maximum capacity for 6 continuous months, during which the Excel produced no odour and produced a clean, safe compost. Only Sun-Mar self-contained units are listed for residential and cottage use by NSF, whose Standard #41 is the toughest composting performance standard in the world.

The 2″ vent is attached at the top back of the Excel and can be installed invisibly by running it through the wall and up the outside wall. For comfort the Excel has a sturdy detachable footrest which can be removed to pull out the finishing drawer.

In normal use the Excel can normally evaporate all liquids, however a ¬Ĺ” emergency drain is fitted at the rear and this should be connected if the unit is to be used residentially or heavily, or if prolonged power outages are expected.

Compact

The Compact is an elegant low profile unit with the looks to complement any bathroom. Sun-Mar engineers designed this low profile toilet by developing and patenting a new variable diameter Bio-drum which is small at the front and large at the rear. To maintain the uninterrupted lines of the Compact, a patented Bio-drum handle recesses into the body of the unit to mix and aerate the compost.

The Compact differs from the Excel in that all three chambers are smaller, which makes the Compact ideally suited to light residential or light to medium cottage use.

As with the Excel, a 2″ vent stack attaches to the rear of the Compact. A 1/2″ emergency drain at the rear offers protection against heavy or residential use, or prolonged power outage.

Compact
Space Saver

The SPACESAVER is a standard three chamber unit designed specifically for situations where space is extremely limited. With a width of only 19″ and depth of 22″, even a closet or small corner can now be turned into a bathroom!

The SPACESAVER is fitted with the same kind of high quality turbo-fan as other electric units have.

The SPACESAVER has almost the same size Bio-drum as the COMPACT, so composting capacity is similar to that of the Compact. On the other hand, evaporation is limited by the smaller heater and evaporating surface, so the safety drains should be connected.

Mobile

No pump-outs!

Recycling Brings Freedom. The original composting toilet for Mobile and Marine applications, no muss and no fuss, no changing containers, no pouring out urine. Self-contained and with a little maintenance works like a charm!
The Sun-Mar Mobile was the first composting toilet specifically designed to recycle waste on boats and recreational vehicles. Less pump-outs! No more chemical toilets! Recycling brings freedom, with the ODOR-FREE operation of a Sun-Mar.

The Design of the Sun-Mar Mobile

Although the Sun-Mar Mobile uses Sun-Mar’s tried and true three-chamber system, “marinizing” the unit led to some interesting adaptations. The need to be able to handle violent motion meant that the finishing drawer had to be gasketed so that no liquid could escape from the evaporating chamber.
The air intakes face the same problem. These have to be located higher up and the air ducted down to the evaporating chamber.

At the same time, a special drum locker ensures that the composting drum is held upright under all sea or road conditions.
