Gravity roof inlet, heated 230V DN160 vertical with leaf basket and bituminous collar for welding with heat-fusible or cold-bonded roofing, inlet body thermally insulated HL62.1H/5

Efficient roof drainage with gravity inlet HL62.1H/5

This vertical gravity roof inlet, equipped with a leaf basket and bituminous collar, is a reliable solution for draining water from flat roofs. Designed for durability and ease of installation, it performs well in both new installations and modernization of existing systems. Thanks to the ability to adapt to different roof layer arrangements – from traditional to inverted, ventilated and green – it is a universal element of every drainage system.

Construction and application

The inlet is made of high-quality polypropylene (PP), which guarantees corrosion resistance and long-term use. The bituminous collar enables a tight connection with the waterproofing layers, ensuring protection against leaks. Additionally, the built-in heater (10-30W/230V) prevents water from freezing in winter, maintaining the continuous operation of the system. The leaf basket effectively stops debris, protecting the drainpipes from clogging and ensuring a free flow of water.

It is worth noting the possibility of a DN160 spigot connection or the use of a compensating spigot from the manufacturer of HDPE welded pipe systems – this provides flexibility in choosing the remaining installation elements. A flow rate of 14.10 l/s ensures effective water drainage even during heavy rainfall.

Advantages for professionals and end users

• Versatility: Possibility of adaptation to different roof layer arrangements thanks to a wide range of additional elements (supporting and drainage rings).
• Tightness: Bituminous collar guarantees a durable and tight connection with waterproofing.
• Freeze protection: Built-in heater ensures continuous operation of the system throughout the year.
• Efficiency: High flow rate (14.10 l/s) effectively drains water during heavy rainfall.
• Easy installation: Push-fit connection simplifies and speeds up installation.
• Durability: Made of polypropylene (PP) ensures corrosion resistance and long-term use.
• Protection against clogging: Leaf basket stops debris, minimizing the risk of failure.
• Higher throughput: Compared to competitive solutions, it offers greater water drainage efficiency.

This inlet is not only a structural element – it is an investment in the safety and comfort of using the roof for years to come.
