Ready, steady, go! The E-TRAILER takes the E-BLOCK electronic 2-unit station everywhere. Armal applied its expertise in the production of trailers for the portable sanitation industry to the innovative E-LINE solutions that are so satisfying for the end user. Compared to the long term usefulness of E-BLOCK, E-TRAILER is more suitable for short term requirements.


The E-TRAILER offers many advantages in an exceptionally small size. Weighing less than 750 Kg, it can be moved by any vehicle with EU B driving license. Stability on site is granted by the adjustable stand to lock the position of the wheels and unfolded stairs’ equipment. Operation modes are no different than those available for all the E-LINE solutions: 

  • self-contained (using external fresh and gray water tanks)
  • mains connected (both water and sewage system)
  • self-contained using the gray water tank and connected to water supply
  • self-contained using the fresh water tank and connected to sewage

Versatility at its best: four operating modes for one product

E-LINE offers a variety of solutions (single restroom, 2-restroom station, 2-restroom trailer), all of them based on the same core technology allowing four operating modes:

  • self-contained (using external fresh and gray water tanks)
  • self-contained using the fresh water tank and connected to sewage
  • self-contained using the gray water tank and connected to water supply
  • mains connected (both water and sewage system)

Operations are very easy and the same knowledge applies to all products. This is a big plus for you, but also for us, as we will further develop this line by creating more products with the same much appreciated technology.
