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, cabins, yurts, and even in light commercial applications.
To simulate residential use the Excel was tested by the National Sanitation Foundation at maximum capacity for six continuous months, during which the Excel produced no odor 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 1/2" 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.

The Excel-NE
The success of the Excel design meant that a three-chamber unit could be specifically designed for those with NO continuous 110 volt supply.  First launched in 1981, the Excel-NE has long been the standard toilet for those living off the grid.  A 1998 redesign gave the unit a rounded look, and recessed the drum handle.  The Excel-NE has no fan or heater.  Odorless operation is achieved by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove.  For good air movement the vent should be installed vertically and to 2-3 feet above the peak of the roof.
The optional 12 volt fan should be installed if you need to install the toilet with any bends in the vent.  No more than two 45 degree bends are encouraged, even with the fan.  If the Excel-NE is used residentially or heavily, or is in a place which is subject to downdraft, the optional 12 volt fan should be installed in the vent stack.  This fan draws 1.4 watts and can be powered by a solar panel and 12 volt marine battery.  (NOTE:  The Thermo-Electric Generator (TEG) with the Kimberly Stove will recharge your marine batteries with the heat from your Kimberly Stove)
Evaporating capacity on the Excel-NE is variable, so the 1" drain at the rear should be connected to an approved drain pit, container, or other facility.

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 cabin 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.

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.  Visit The Sun-Mar website for more information on handling excess liquid.

The Mobile - For Use In Campers, Motorhomes, RVs, Boats etc.

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.  NO pump outs!!  No more chemical toilets!!  Recycling brings freedom, with the ODOR FREE operation of a Sun-Mar.
Although the Sun-Mar Mobile uses Sun-Mar's tried and true three-chamber system, "marinizing" the unit led to some interesting adaptions.  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.  Space constraints means that a fold away foot rest is needed on the unit.  This footrest has spring loaded legs, and a safety release mechanism to enable it to be removed periodically when access to the finishing drawer is required.  
To assist the 12 Volt fan in providing adequate venting, the Sun-Mar Mobile is unique among Sun-Mar units in having a 3" vent stack.  Customers need to supply their own deck vents, which should be constructed to allow adequate air movement while preventing seawater from entering the unit.
Carbon and Zeolite Filter - While venting is optimal above deck level, some installations will require that the deck vent is flush with the deck.  Sun-Mar has incorporated the use of activated carbon and zeolite filter materials in the fan box to "scrub" the air of fresh ammonia odors. This has proven successful, and ensure odor free operation at deck level.
Evaporation and Electrical Configuration -Evaporation is aided by a 110 volt, 120 watt heater and thermostat.  This heater is located in the sealed base compartment.  The thinking in designing a 110 volt heater into the unit was that a 12 volt supply is often available while the unit is in motion, while the 110 volt heater can frequently be used while the vehicle is in an RV park, or, in the case of a vessel, hooked up to shore supply.  There should be enough 12 volt battery power to keep the 12 volt 4.0 watt fan running continuously, and it hooks up on a separate circuit to facilitate this.
Overflow Drain Required - Evaporation capacity on Sun-Mar Mobile Units is limited by the size of the heater, the surface area of the evaporation chamber, and the volume of air movement.  Consequently, arrangements should be made to connect the Sun-Mar Mobile drains to a container, or small holding tank for disposal in an approved manner.
