Roof or terrace drain for pedestrian traffic, gravity-fed DN110 vertical with a stainless steel grate and bolted steel ring HL62B/1

Roof and terrace water drainage – reliable gravity drain DN110

This vertical roof/terrace inlet, made of durable polypropylene (PP), is the optimal solution for effectively draining water from pedestrian areas. Designed by the renowned company HL Hutterer & Lechner, it provides reliable operation and easy installation. A key element is the steel clamping ring, which allows for a tight connection with the roof waterproofing layers, minimizing the risk of leaks. A flow rate of 6.0 l/s guarantees effective drainage even during heavy rainfall.

Design and application

The inlet is designed for versatility. The ability to adapt to different roof layer configurations thanks to additional elements (HL062B.3E or HL160/HL161 drainage support rings) makes it an ideal choice for professionals and individual investors. The stainless steel grating not only ensures durability but also an aesthetic appearance. The possibility of connecting a DN110 spigot or using the manufacturer's HDPE welded pipe compensating spigot increases installation flexibility.

Advantages for the installer and end user

• Versatility: Compatible with various types of roofs and water drainage systems.
• Tightness: The steel clamping ring guarantees a durable and waterproof connection with the roof membrane.
• Durability: Made of high-quality materials – polypropylene and stainless steel – ensures long-term use without frequent replacement.
• Easy installation: The inlet design is designed for simplicity of installation, which translates into saving time and labor costs.
• Efficiency: A flow rate of 6.0 l/s effectively drains water even during heavy rainfall.
• Wide range of accessories: Availability of additional elements (extensions, rings) allows adaptation to the specific requirements of each project.
• Expandability: Compatibility with the HL350 system and other HL elements allows for the creation of comprehensive drainage solutions.

It is also worth mentioning the possibility of using adapters and extension elements, which allows for precise adaptation of the inlet to specific installation conditions and roof layer heights. This gives the investor confidence that the system will operate optimally for many years.
