Drainage channel with central siphon BHS-G BHS-AB0500-200AK

A stainless steel drainage channel collects and directs wastewater across kitchen floors, preventing pooling and slip hazards. The channel slopes gently towards a central siphon, using gravity to guide liquid into the drainage system while trapping odours below the water seal. This method avoids mechanical pumps and relies on the channel's built-in fall to keep water moving continuously, even under heavy flow from hoses or spills.

The operator installs the channel into the floor during construction or refurbishment, aligning the side walls with levelling pins to ensure a consistent fall. Once the channel is set, the chosen edge profile—standard, vinyl-compatible or tiled—is fitted to match the surrounding floor finish. A mesh grating is placed over the channel to support foot traffic and catch debris, while allowing water to pass through. The siphon connects to a DN100 stainless steel pipe, which carries wastewater to the building's drainage network.

Constructed as a single welded unit from AISI 304 stainless steel, the channel resists corrosion and withstands the weight of trolleys and boots. The steel thickness ranges from 0.8 mm to 2.0 mm, providing strength without excessive weight. Side walls include levelling pins for precise alignment during installation.

The channel is available with different edge profiles to suit standard, vinyl or tiled floors. Optional mesh gratings come in smooth or anti-slip finishes and various mesh sizes, allowing customisation for hygiene and safety requirements.

Measuring 2000 mm long and 300 mm wide, the channel fits beneath worktops or along walkways where water collects. The central siphon position balances flow from both ends, reducing the risk of blockages. The 2000 mm length spans typical kitchen bays, while the 300 mm width provides sufficient capacity for spills without occupying excessive floor space.

Cleaning involves removing the grating and flushing the channel with water to clear debris. The welded construction eliminates joints where dirt can accumulate, and the stainless steel surface resists staining and chemical damage. The siphon requires periodic inspection to ensure the water seal remains intact and odours are contained.
