Roof inlet gravity DrainBox DN110 vertical, with bituminous collar d500mm, heated (10-30W/230V) HL63.1H/1

Effective flat roof drainage with frost protection

This vertical gravity roof inlet DrainBox DN110, equipped with a bituminous collar with a diameter of 500mm, is a reliable solution for draining water from flat roofs. Its corrugated sheet metal construction provides strength and resistance to weather conditions. The inlet is height-adjustable (100-160mm), making it easy to adapt to specific mounting conditions.

Design and functionality

The inlet combines a solid construction with practical solutions. A DN110 spigot connection or a welded HDPE system compensating socket guarantees a tight and durable connection. A flow rate of 8.70 l/s ensures effective water drainage even during heavy rainfall. A key element is the built-in, self-regulating heating set (10-30W/230V), which prevents the formation of ice blockages during the winter. This is particularly important in regions with harsh climates, where freezing water can lead to serious damage to the roof.

Advantages for the installer and end user

• Universal mounting: Adjustable height and the ability to connect to various water drainage systems make installation easier in different types of roof structures.
• Frost protection: The integrated heating system eliminates the risk of the inlet clogging with ice and snow, ensuring continuous operation throughout the year. This translates into greater comfort and minimizes the risk of damage caused by water.
• Durability and reliability: The materials used – corrugated sheet metal, polypropylene (PP) – guarantee a long service life and resistance to corrosion and weathering.
• Easy maintenance: The design of the inlet allows easy access to elements requiring cleaning or replacement.
• Tightness: The bituminous collar ensures a tight connection between the inlet and the roofing, preventing leaks.
• Efficiency: A flow rate of 8.7 l/s effectively drains water even during heavy downpours.

This roof inlet is an investment in the safety and durability of the roof, which is appreciated by both professional installers and end users. It not only provides effective water drainage, but also minimizes the risk of problems related to freezing and leaks.
