Tool-free and time-saving

The connectors are designed for installation without screws or special tools. This saves valuable time during assembly and significantly reduces the workload on the construction site. The modules are simply slotted together and secured with the system connectors – one click, and the connection is secure.

Strong connection – flexible expansion

Despite their ease of use, the system channel connectors offer a rigid and durable connection between the individual channel segments. The system remains dimensionally stable, even over longer channel runs or on uneven surfaces. At the same time, the construction remains modular and expandable - additional modules can be added or removed at any time.

Tight and reliable

In combination with the water-neutral sealing paste and the sealing membrane at the wall connection, the connectors ensure that the system captures almost 100% of the dirty and cleaning water. The transitions between the modules are designed to prevent leaks – even under intensive use or changing weather conditions.

For use behind scaffolding and on structured facades

The system gutter connectors are particularly helpful when the gutter is installed behind existing scaffolding or when the facade has rough textures. They allow for flexible adjustment of the gutter routing and ensure that the connection holds reliably even under difficult conditions.

Specifically designed for facade cleaning. The wastewater collection tray, or wastewater channel SR from A3 Innoteg GmbH, is one of the Praxis developed solution for collecting cleaning and wastewater on vertical surfaces.

The clean solution for your facade cleaning

Anyone who prioritizes quality and environmental awareness in facade cleaning will find the SR wastewater collection tray indispensable. It protects floors and drains from contaminated water and ensures a professional, sustainable working method.

✓ Legally compliant
✓ Mobile and expandable
✓ Quickly installed & efficient

Compared to conventional methods for collecting wastewater and service water (e.g. foil and rubber trays), the SR wastewater channel offers many advantages.

The advantages of the channel

• Customizable to your individual requirements
• Modularly expandable
• low weight
• Short setup times thanks to quick and easy assembly
• Facade connection to coarsely structured facades possible
• Construction behind an existing scaffold is possible
• Uneven ground can be bridged.
• Nearly 100% of the wastewater and process water is collected.

Innovation from practice

The wastewater collection tray was developed by A3 Innoteg GmbH in collaboration with specialist companies. The goal was to create a solution that is easy to use, functions reliably, and meets the highest environmental standards.
Unlike conventional collection methods, the tray, like a channel, offers a stable, modular construction. The basic set is 6 meters long and can be flexibly extended with 2-meter modules. Connection is tool-free – quick, safe, and efficient.

Sealing that convinces

A water-neutral sealing paste ensures a reliable seal between the modules. The wall connection is almost completely sealed with a special sealing membrane – even on uneven or textured facades.
After installation, the channel is pressed against the wall using ballast bags. The brush comb adapts to the surface, and the suction hose is connected according to the floor slope. The suction hose is connected to the end module according to the floor slope, and the other end is sealed with a blanking plug. The water can then be drained directly or filtered using our in-house accessories such as the suction pressure system or Filter system Other systems also allow for efficient operation.

Made for professionals

The SR wastewater collection tray is robust, lightweight and quick to set up. It bridges uneven ground, can be mounted behind scaffolding, and offers a virtually complete collection rate.This makes it ideal for simple as well as very demanding cleaning projects.

Designed for practical use

The SR wastewater collection tray from A3 Innoteg GmbH was specifically developed for the requirements of facade cleaning. It offers a well-designed and field-tested solution for collecting cleaning and wastewater on vertical surfaces.
Compared to conventional collection methods such as liners or rubber trays, the SR wastewater collection tray impresses with its robust construction, ease of use, and high efficiency. Its modular design allows for flexible adaptation to on-site conditions.

Modular and flexible

The basic set of wastewater collection trays/channels is 6m long. It can be extended as needed using 2m extension modules. The individual modules are connected without tools using system connectors, resulting in a stable, rigid channel. A water-neutral sealant is used to seal between the modules.
The seal between the wall connection and the gutter is particularly effective: By using a special sealing membrane between the gutter and the brush comb, an almost 100% seal is achieved. Even with coarsely structured facades.

The advantages of the wastewater collection tray

• Customizable to your individual requirements
• Modularly expandable
• low weight
• Short setup times thanks to quick and easy assembly
• Facade connection to coarsely structured facades possible
• Construction behind an existing scaffold is possible
• Uneven ground can be bridged.
• Nearly 100% of the wastewater and process water is collected.

Easy to assemble and use

After installation, the wastewater system is placed against the facade and evenly secured with light pressure using the included ballast bags, allowing the brushcomb to conform to the wall/facade's structure.The suction hose is connected to the end module according to the slope of the floor, and the other end is sealed with the blanking plug.
The runoff water can now be pumped or vacuumed out of the collection tray/channel. Filtration is also possible; for this, our optional accessories are available, e.g., the suction pressure system or the filter system.

Sustainability and efficiency

The SR wastewater channel enables a resource-saving and sustainable facade cleaning.It protects the environment, meets legal requirements and saves time during assembly.Uneven ground can be easily bridged, and assembly behind an existing scaffold is also possible.
