Roof inlet gravity DN75/110 horizontal, heated (10-30W/230V), stainless steel mesh 137x137mm HL64.1B

Roof Water Drainage – Reliable Gravity Inlet with Heating Function

This roof inlet, designed for gravity drainage of roofs and terraces with pedestrian traffic, is a solution combining functionality and protection against freezing. Equipped with a built-in heating system (10-30W/230V), it prevents ice formation and ensures continuous water drainage, even in harsh weather conditions. The grate made of high-grade stainless steel guarantees durability and corrosion resistance.

Design and Application

The inlet features a horizontal outlet DN75/110, which facilitates integration with the existing installation. The possibility of using a socket connection or a manufacturer's HDPE pipe compensating socket allows for flexible adaptation to different water drainage systems. Thanks to a wide range of additional elements, such as support and drainage rings, the inlet can be adapted to various roof layer configurations. It ensures a tight connection with the waterproofing layers, minimizing the risk of leaks. A flow rate of 3.7 l/s guarantees effective water drainage even during heavy rainfall.

Advantages for Professionals and Users

• Freeze Protection: The built-in heating system eliminates the problem of ice formation, ensuring continuous system operation throughout the year. This is particularly important in regions with harsh winters.
• Universal Mounting: The ability to adapt to different roof layer configurations thanks to a wide range of additional elements simplifies installation and reduces adaptation costs.
• Durability and Resistance: Made of high-quality polypropylene (PP) and a grate made of high-grade stainless steel, it ensures long-term operation without frequent replacement.
• Efficient Drainage: A flow rate of 3.7 l/s effectively handles large amounts of rainwater, protecting the building from flooding.
• Easy Integration: The DN75/110 socket connection and the possibility of using a compensating socket facilitate connection to the existing sewage infrastructure.
• Mechanical Strength: Load class K (300 kg) makes the inlet suitable for use in areas with high pedestrian traffic.
