COMPOSTING TOILETS

Sun-Mar Composting Toilets

These toilets are made in Canada, produce no pollution, and do not leave any trace or footprint whatsoever! Since toilet waste is 90% water, these units ensure it is evaporated and returned to the atmosphere through their vent systems. The small amount of solid matter left behind is re-cycled into a useful, fertilizing soil. They use no chemicals or septic systems and, therefore, can be used in the most fragile environments. The Sun-Mar systems produce no pollutants while collecting nutrients, and are an environmentally healthy choice for re-cycling human waste.

Sun-Mar toilets are odour free! As well as ensuring an aerobic breakdown in the Bio-drum, Sun-Mar ensures an odour free environment by engineering the air flow within the unit to maintain a partial vacuum at all times. Air is drawn in either by a fan (or on non-electric units by the vent chimney) over the evaporating chamber and up the vent stack. Not only does this allow evaporation of excess liquid, but by continuously pulling air in it ensures no smell escapes from the unit.

Sun-Mar has the only Residential and Cottage use composting toilet systems certified and listed under NSF (National Sanitation Foundation) Standard 41.

A sample of some of the models available:

Features

• Water Free
• Quick & easy to install
• Easy to winterize
• Economical because they are one piece systems
• Easy to clean having a durable, shiny finish

Features

• Available as either electric or non-electric
• The Centrex 1000 model is ideal for those who want a unit for a light seasonal application
• All central units, including the Centrex 1000 series, are fitted with a removable evaporating tray under the drum screen in the evaporating chamber. This tray helps to trap any peat moss debris, and provides an extra evaporating surface.
• In light to medium seasonal use the Centrex 1000 is typically able to hold compost for the full cottage season, and compost needs extraction only in the spring.
• The electric Centrex 1000 features a 260 watt heater in a sealed compartment under the unit and the standard Sun-Mar 25 watt turbo fan and 2" vent stack to ensure odourless operation.
• The Centrex 1000 Non Electric does not normally need a 12 Volt fan for the 4" stack, but a 1.4 Watt fan is available if required (where a bend needs to be installed in the vent stack, a 12 Volt fan is required).
• All 1000 series units are supplied with a 1" drain hose which should be connected to the 1" drain at the bottom left of the unit.
• The 1000 series is designed only for use with 1 pint flush toilets (purchased separately).

Features

• Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle, and larger waste volumes.
• When used seasonally by up to 7-9 adults, compost will normally only need removing annually each spring. In residential use, compost will have to be extracted more frequently.
• The Centrex 2000 NE (Non-Electric) is the non-electric version of the Centrex 2000 which is fitted with a 4" vent stack. Installation of a 12 Volt fan is optional, but it is recommended for heavy seasonal, residential use, or where the installation is particularly subject to downdraft, being surrounded by high trees or hills. We also recommend the fan if you need to install a bend in your vent stack.
• The Centrex 2000 E (Electric) features a 370 watt thermostatically controlled heater in a sealed compartment under the unit and the standard Sun-Mar 30 watt turbo fan, with a 2" vent stack to remove evaporating liquid and fresh odours.
• 2000 series units are supplied with a 1" drain hose which should be connected to the 1" drain at the bottom of the unit.
• The Centrex 2000 NE must be used with one or more Sealand Low Flush Toilets - purchased separately.

Features

• The Centrex 3000 utilizes a continuous flow design for very heavy cottage or medium residential use. With a continuous flow system, rotation of the drum moves compost along the larger and longer 3000 series drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions the drum will not have to be turned backwards for emptying.
• All Centrex 3000 electric units feature a 370 watt 120 volt thermostatically controlled heater in a sealed compartment beneath the unit coupled with the standard Sun-Mar 30 watt turbo fan and 2" vent stack. This heater assists in evaporation of liquids, reducing the amount of effluent from the unit. The fan also removes any fresh odours from the unit, ensuring odour-free operation.
• All Centrex 3000 series units are supplied with a 1" drain hose which should be connected to the 1" drain at the bottom left of the unit.
• This unit is for use with Sealand Low Flush Toilets, purchased separately. More than one toilet may be installed on this system.

Features

• Sun-Mar offers a selection of 1 pint flush toilets for use with regular Centrex 1000, 2000, and 3000 series central composting toilet systems. More than one "1 pint flush" toilet can be installed with these units if necessary. The constraint is the number of people using the system rather than the number of toilets.
• Using about one pint per flush, these ultra low flush toilets provide all the advantages of a flush toilet while minimizing water usage. They are ideal for use with Sun-Mar Central Composting Systems, but can also be used with holding tanks, overloaded septic systems, and in RV's.
• A simple foot pedal flush opens the water valve and gate when pushed down, and fills the bowl with water when lifted. After flushing, a small amount of water is held in the toilet bowl which is sealed by a self-cleaning ball valve and teflon seal. Even gravity-fed water from a roof tank is sufficient to flush a Sealand toilet. In winter they can be flushed manually using a container if necessary.
• The Sealand 510 Plus has a regular sized toilet seat. In some instances extra height is needed to allow the toilet to gravity feed to the composting unit. Where this is the case, the Sealand 511 Plus, a low profile model with a 10" seat height, can be mounted on a platform.
• For Sun-Mar installations, we recommend the 510 Plus as the unit of choice as it has the size and appearance of a "regular" toilet.
• Sealand toilets are available in either White or Bone. They come complete except for the required 3", 4-bolt, floor flange which is purchased separately.
