Hygienic Round Bottom Channel
More laminar flow in comparison with typical rectangular shape bottom of the channel – faster transfer of fluids to the outlet. User needs less amount of water to keep thechannel clean – ecology & efficiency.
The discharge of fluids into the channel causes less pollution – reduction of the bacteria accumulation.
They are used to collect waste from the surface of the floor and drain it into the sewage system. Drainages of this type are used in food plants (breweries, dairies, abattoirs) and chemical industry plants.
PRODUCTION TECHNOLOGY
Standard channels are manufactured in a wide range of dimensions and shapes. They are produced according to a drawing prepared as a result of cooperation between an investor, a designer or a technologist and ATT engineers. By standard, we use sheet metal
of 2 [mm] thickness made of AISI 304, EN 1.4301 or AISI 316L, EN 1.4404 grade steel for production. The drainpipes have built-in bottom slope, which by standard is 0,5%. There is a possibility to adapt the size of the slope to a specific project. In order to facilitate installation, each channel is equipped
with rectifying screws and anchoring elements. They allow correct levelling of the drainpipe and its settling in concrete.
Options
– Basket under the entire length of the channel
– 3 mm thickness
– Hinged grates
Design
– flow is more laminar in comparison with typical
rectangular shape bottom of the channel
– the discharge of fluids into the channel causes less pollution
– user needs less amount of water to keep the channel clean
Benefits:
– faster transfer of fluids to the outlet
– reduction of the bacteria accumulation
– ecology & efficiency

Channel Edge Finishing
The edge finishing should depend on the flooring and wastewater temperature.
We can offer the following options:
1 – with downward flange (standard)
2 – with flange
3 – with raised back edge
4 – with edge angle section for the expansion joint in the floor
5 – with tightly plately folded edges
6 – for a vinyl floor
