We answer your questions about our rectangular kitchen channels

canal cocina inoxA rectangular channel is a drainage system specifically designed to collect and discharge wastewater. This linear system is characterised by its rectangular shape, which facilitates its integration into flat surfaces and allows it to adapt to various floor designs. 

The fact that these types of channels are manufactured entirely from stainless steel makes them particularly appealing due to the ease of their proper maintenance and cleaning. They are wide and shallow enclosed channels, with an internal slope and direct outlets from the channel base, which can be positioned at any point along the channel. 

They also incorporate removable traps and strainers or collection baskets for solids to prevent impurities from passing into the drainage pipes. They can have various widths between 100 and 400 mm, with vertical or horizontal outlets of DN160, 110 or 75 mm.

Furthermore, they feature anti-slip gratings specifically designed for wet areas. We can manufacture the channels with slotted, perforated or bar gratings depending on the project requirements.

Rectangular kitchen channels are indispensable in environments where wastewater flow requires reliable and high-performance drainage solutions. Our channels have been specifically designed for use in hotel kitchens, restaurants, and catering facilities.

While our rectangular stainless steel channels are primarily known as kitchen channels, given their most common application, their versatility extends far beyond that. They are the ideal choice for any location where water evacuation must be fast, safe, and controlled, suitable for both large areas and smaller facilities.

For instance, they are suitable for draining fish counters in supermarkets, in pharmaceutical laboratories, or in healthcare applications where very high cleaning and disinfection standards are required.

The slope of a rectangular channel is an essential parameter to ensure that water flows correctly towards the drain, preventing stagnation or backflow. The ideal slope depends on the channel length, the expected water volume, and the available space for installation.

Before reviewing the recommended values, consider that an incorrect slope can compromise the entire drainage system, so it is always best to leave this calculation to experts.

Generally, the recommended slope for rectangular channels ranges between 1% and 2% (i.e., between 1 and 2 cm of drop per metre of length). This range promotes constant water evacuation, prevents blockages, and helps keep the channel clean, reducing the necessary maintenance.

One of the most critical points in any drainage installation is determining the flow rate that the rectangular channel must withstand. This calculation ensures that the system can evacuate all necessary water without causing overflows or dangerous accumulations.

Before showing you how it is calculated, remember that at Inza, we are at your disposal to resolve any queries related to our rectangular channels.

To calculate the flow rate of a rectangular channel, you must take into account the width, depth, length, and slope of the channel, in addition to the water flow generated in the area. In general, the formula used is:

Q = A × V

where Q is the flow rate (m³/s), A is the cross-sectional area (m²), and V is the average water velocity (m/s)

This calculation may seem complex, but at Inza, we do it for you, always ensuring that the system complies with current regulations and that evacuation is efficient, even in situations of maximum demand.
