Waterless No Flush Urinal

BlueSeal® - It’s what makes No-Flush™ urinals work all over the world!

For the past 25 years, BlueSeal has been our long lasting and biodegradable trap seal liquid. It is what we are known for. BlueSeal® has a specific gravity lower than water or urine. In the EcoTreap cartridge it floats on top of water/urine and so makes a complete seal. It therefore remains for an extended period of time in the trap even with urinal use (small amounts do get carried out with each urinal use). Otherwise, with no use to the urinal or little use, such as in outlying facilities, BlueSeal remains indefinitely in the trap sealing trap odors.

BlueSeal has zero evaporation at 100 degrees F and does not freeze above -70 degrees F. Typical winterization costs can be eliminated by installing our Waterless No-Flush urinals.

Commercially available cleaners will not harm the BlueSeal in the EcoTrap®, meaning no special cleaners need to be purchased.

Adding BlueSeal to any non-water using urinals is very simple: squeeze the quart bottle to fill the PortionAid to 3 oz (100ml). Empty the 3 oz. contents from the PortionAid into the trap/cartridge. Done! Please follow instructions on the bottle.

Note: The cleaning of Waterless urinals is effected the same way as cleaning conventional urinals. Replenishments of BlueSeal are simple and accurately measured with a PortionAid. Fill the PortionAid on top of the bottle by simply squeezing the bottle. Pour contents directly into the holes of the EcoTrap/cartridge. The PortionAid minimizes the waste of BlueSeal.

EcoTrap® Inside | Simplicity is its Beauty!




  Maintenance instruction
  • Our patented EcoTrap® relies on the proven and simple vertical trap principle.
  • Urine flows down into the EcoTrap drain insert.
  • In the EcoTrap the urine passes through a floating layer of BlueSeal®liquid, which forms a barrier that prevents sewer vapors from escaping to the restroom atmosphere.
  • Urine under the barrier layer overflows into the central tube and runs down to the conventional drain line.
  • The layer of approx. 3 ounces of BlueSeal will last for about 1500 sanitary uses. The liquid is then simply replenished. Task time: 20 seconds.Trap does not need to be touched.
  • The EcoTrap retains urine sediments and is easily replaced 2-4 times a year according to traffic to the fixture. A special tool, the X-Traptor®, is used to remove the EcoTrap®. This deters vandalism. Task time: 3-4 minutes.
  • Please see our simple maintenance instructions here.
  • The patented vertical EcoTrap design provides superior efficiencies to other, more complicated trap arrangements. It does not need to be cleaned out as it is simply changed out. It also helps retain urine sediments. Urinals without trap inserts may clog the urinal's internal trapway.
