ACO Qmax

ACO Qmax is a versatile and robust slot drainage system engineered for effective stormwater conveyance, storage, and attenuation. Its unique design and material composition offer several advantages for modern surface water management

Key Features

• High Hydraulic Capacity: The system is designed to efficiently collect and transport large volumes of surface water, even during heavy rainfall events. Larger channel sizes offer significant in-built storage capacity.
• Discreet Slot Inlet: The narrow, continuous slot opening provides an unobtrusive and aesthetically pleasing drainage solution that integrates well with various surface finishes (asphalt, concrete, block paving, natural stone). Different slot rail designs (Q-Flow, Q-Guard, Q-Slot) cater to varying intake capacities and pedestrian safety requirements.
• Modular Polyethylene (PE) Channels: Manufactured from lightweight and durable PE (including recycled material), the 2-meter long channel units are easy to handle, quick to install, and resistant to corrosion and chemicals.
• Integrated Storage and Attenuation: The larger Qmax channel sizes (150 to 900) offer substantial internal volume for temporary stormwater storage (attenuation), helping to reduce peak flows and the impact on downstream drainage networks. This can eliminate the need for separate attenuation tanks in some applications.
• Load Class Versatility: Certified for load classes ranging from A15 (pedestrian) to F900 (heavy vehicular traffic, including airports), making it suitable for a wide range of applications.
• Sealed System: Integrated seals at the push-fit channel joints ensure a watertight connection, preventing leakage and maintaining water quality within the system.
• Sustainable Drainage System (SuDS) Component: ACO Qmax is designed to be an integral part of SuDS, allowing for the combination of "hard" (engineered) and "soft" (natural) SuDS elements to achieve quality, quantity, and amenity benefits.
• Carbon Neutral Option: ACO Qmax is available as a Carbon Neutral certified product (cradle to gate), minimizing its environmental impact.
• Easy Installation: The lightweight material and push-fit connections contribute to fast and straightforward installation, reducing on-site labor.
• Range of Accessories: A comprehensive range of accessories is available, including access chambers, silt traps, end caps, outlet connectors, and step connectors for easy integration with other drainage components.
• Compatibility with Flow Control: ACO Qmax can be used in conjunction with the ACO Q-Brake Vortex flow control unit to regulate stormwater discharge rates.

• Qmax 150, 225, 300, 350, 465, 600, 700, 900: These numbers indicate the internal width of the channel in millimeters, with larger widths offering greater hydraulic capacity and attenuation volume.
• Qmax Neo: An "Efficient Option" made from Polypropylene (PP), offering similar benefits with a focus on optimized material usage and transport.
• Retention Channels (e.g., Qmax 550, 700, 900): Specifically designed with larger internal volumes for enhanced stormwater attenuation.

Materials Used for Production

• Channel Body: Polyethylene (PE), including recycled PE, or Polypropylene (PP) for Qmax Neo.
• Edge Rails: Available in various materials depending on the specific Qmax variant and application, including:
  • ATec coated ductile iron
  • Hot-dipped galvanized steel
  • Composite plastic
• Slot Inlets: Typically made from coated ductile iron, galvanized steel, or stainless steel, depending on the edge rail material and aesthetic requirements.

• Airport pavements
• Highways and motorways
• Commercial and industrial areas
• Car parks and loading docks
• Pedestrian precincts and plazas
• Landscaping and urban design
• Sports facilities
• Areas requiring high hydraulic capacity and stormwater attenuation
• Sustainable urban drainage schemes (SuDS)
