SR Series    Waterless Incinerating Toilet

The SR series include environmentally friendly incinerating toilets that lead the way in the waterless disposal of waste. It was developed to solve economical and logistical problems in remote waste handling applications; in such applications, there may not be any available sewage systems; septic tanks may not be allowed; or it is simply expensive or difficult to install a standard water flushing toilet. Every model is waterless self-contained toilet that incinerates the waste into a sterile ash that needs to be emptied periodically.

Models

SR5 - 4 people full time; cabin, summer house, lower capacity usage areas
SR12 - 8-10 people full time; residential and smaller commercial applications - oil rigs, construction sites, camps, military, refugee camps, disaster relief, house boats etc

OPERATION

After the toilet has been used, all waste material and paper gets moved into the burn chamber by an auger. The incineration process continues until all of the waste material is gone. This process takes about 5-10 minutes for a short cycle (liquid waste) and 35- 40 minutes for long cycle.

The SR5 models use propane, and the SR12 models run on propane, natural gas, or diesel. In addition 12V DC, 120V AC, or 240V AC is required. The electricity is required to run the auger and commence the burn cycles.

The toilets have a built in circuit board that monitors the operations and will let the user know if the burn cycles have completed, max capacity, or if there are any error i.e. out of fuel.

INSTALLATION

Given that the toilet is a completely self contained, the installation process is straight forward and can be done by a general contractor. Once the included chimney system has been installed through the roof or out through the wall with an elbow, the fuel line and power source can be connected. Following connecting the power, and checking for any fuel leaks as per directions in the owner's manual, one can start to use the toilet.

  • Completely self-contained. No need to install any separate tanks (except fuel)
  • Must be installed inside a weather proof building/structure
  • Requires 5 inches clearance from any wall
  • 1 ft clearance is recommended behind the toilet in order to access the burn chamber clean out port
  • Should not be installed or operated in an area where there is a risk of an accumulation of flammable vapors or dust
  • The chimney has to be a minimum of 7 ft long
  • The chimney can be vented out through the side wall using elbows

If the toilet has to be left for a certain time, simply shut down the power and turn off the power.

   

CLEANING AND MAINTENANCE

Periodically, the burn chamber needs to be emptied of sterile ash. Cleaning of ashes can be done from the outside of the toilet; a special cleaning lid and cap to the burn chamber can be accessed from the back of the unit. A standard ShopVac is recommended to use to vacuum the ashes.   

The toilets are all equipped with a small water reservoir of about 1 quart of water. By pushing a rinse button, water rinses the bowl and auger. In addition, bowl liners may be used.  As an option, a catalytic converter with a fan that cleans the outgoing air is also available for the SR5.

SAFTY
The SR series has been carefully tested and approved by various certifying institutions. The latest approval was done by Underwriters Laboratory (UL), which is one of the most credible institutions in the U.S. for product safety. In addition to UL approval, the SR models have also been approved by multiple European laboratories (earning the CE mark for excellence in product safety and design), and a Department of Environmental Quality (DEQ) approval in the state of Idaho. http://www.deq.state.id.us The SR is safe when installed and operated in accordance with the owner's manual.
