Drainage channel with central siphon BHS-G BHS-AB0500-150AK

A drainage channel collects surface water across its length and directs it to a single outlet, preventing pooling on kitchen floors. The channel slopes gently towards the central siphon, using gravity to move water without pumps or moving parts. The siphon traps odours and debris, stopping them from rising back into the workspace while allowing water to flow through. This design keeps floors dry, reduces slip hazards and simplifies cleaning in busy catering environments where spills and washdowns are frequent.

The operator installs the channel level with the finished floor, aligning the side walls with levelling pins to ensure a consistent fall towards the outlet. Once positioned, the chosen edge profile is fitted to match the surrounding floor finish—standard, vinyl or tiled. The siphon is connected to a DN100 stainless steel pipe, which carries water to the building's drainage system. Optional mesh gratings are placed over the channel to catch debris while allowing water to pass through; the choice of smooth or anti-slip mesh depends on the traffic and hygiene requirements of the area.

Constructed from AISI 304 stainless steel, the channel is welded into a single hermetic unit, eliminating leaks and corrosion. The steel thickness ranges from 0.8 to 2.0 mm, providing strength without excessive weight. The flat base and sloping design ensure water flows efficiently, while the central siphon simplifies maintenance by concentrating waste in one accessible location.

The channel's 1500 x 300 mm footprint suits medium to large wet areas, such as dishwashing zones, prep stations or walk-in refrigeration entrances. Its one-part grade means the entire unit is delivered as a single piece, reducing installation time and potential misalignment. The external pipe diameter of 108 mm ensures compatibility with standard drainage fittings, avoiding the need for adapters or custom connections.

Cleaning involves removing the grating and flushing the channel with water to clear debris. The siphon is checked periodically to ensure it remains free of blockages, while the stainless steel surface can be wiped down or scrubbed with non-abrasive cleaners to maintain hygiene. The welded construction prevents dirt from accumulating in seams, making upkeep straightforward.

Available edge profiles allow the channel to integrate seamlessly with different floor types, ensuring a smooth transition between the grating and the surrounding surface. Optional gratings with varying mesh sizes provide flexibility for areas with fine debris or heavy foot traffic. The product can also be ordered in custom sizes to fit specific layouts, maintaining the same construction and features as the standard 1500 x 300 mm model.

This drainage channel is categorised under floor drainage systems for professional kitchens and wet areas, where efficient water removal and hygiene are critical.
