The slot channels are known as “Ulmer Rinne” on the market. These channels, which are visible from the top, are the ideal solution for areas with low runoff wastewater, eg slaughterhouses, butcher shops, breweries and wineries. The channels can be easily combined with the ETU-channels and drains. So the variations are endless.
> With closed channel bodies; the water is collected by the channel and drained away as quickly as possible
> With drainage slots on one side; the water is collected by the channel and released into the neighbouring sub-soil
The slotted channels are produced as a single part to guarantee as a high level of mechanical stability as possible. The inlet sleeve height can be customised. The slotted channels are cleaned via inspection boxes. As part of its customisation service, ETU can produce the slotted channels as arcs with different radii, and with varying lengths, heights, slot widths and covers to suit your every need.
