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

Effective roof drainage – regardless of the weather

This vertical gravity roof inlet DrainBox DN110 is a solution for demanding installations where reliability and protection against the effects of low temperatures are key. Designed for effective drainage of water from roofs, especially those exposed to snow and ice loads. Its construction combines solid workmanship with well-thought-out technical solutions, ensuring long-lasting and trouble-free operation.

Construction and application

The inlet is characterized by a housing in the form of a box with adjustable height (100-160mm), which makes it easier to adapt to specific mounting conditions. Made of durable corrugated sheet metal, it provides resistance to mechanical damage and corrosion. The possibility of connecting a spigot DN110 or a compensating HDPE spigot guarantees compatibility with various drainage systems. A PVC collar with a diameter of 500mm ensures a tight connection with the roofing material.

The built-in self-regulating heating set (10-30W/230V) is a key feature of this inlet. It prevents the formation of ice blockages, maintaining the patency of the drain even in difficult winter conditions. The heating system is energy-saving and adjusts its power to current needs, minimizing energy consumption. A flow rate of 5.82 l/s ensures quick and efficient drainage of rainwater.

Advantages for professionals and users

• Freeze protection: The self-regulating heating system eliminates the risk of clogging the inlet with snow and ice, which translates into trouble-free operation of the installation throughout the year.
• Universal mounting: Adjustable housing height and the ability to connect different types of spigots make installation easier in various roof configurations.
• Durability and resistance: Made of high-quality materials (corrugated sheet metal, PVC) guarantees long life and resistance to weather conditions.
• Efficiency: High flow rate (5.82 l/s) ensures rapid drainage of rainwater, minimizing the risk of leaks and damage to the roof structure.
• Simple installation: The large diameter PVC collar facilitates a tight connection with the roofing membrane – “dress membrane over flange and clamp” system.
• Energy saving: The self-regulating heating system adjusts the power consumption to current needs, minimizing operating costs.

This inlet is an investment in the safety and comfort of using the roof – both for the installer who appreciates ease of installation and product reliability, and for the end user who will be confident in efficient drainage regardless of the weather.
