Roof inlet gravity DN75/110 horizontal, with welded bituminous collar d500mm, heated (10-30W/230V), stainless steel drain grate 137x137mm HL64.1BH

Efficient roof drainage with gravitational inlet HL64.1BH

This roof inlet, designed for gravitational drainage of roofs and terraces with pedestrian traffic, is a reliable solution for effective water drainage. The horizontal construction with a welded bituminous collar with a diameter of 500 mm ensures a tight connection with the waterproofing layers, minimizing the risk of leaks and damage. The built-in heating system (10-30W/230V) prevents water from freezing in winter, maintaining the continuity of drainage operation even in harsh weather conditions. The drain grate made of high-quality stainless steel guarantees durability and corrosion resistance.

Versatility and easy installation

The HL64.1BH inlet stands out for its high flexibility in adapting to different roof layer configurations. Thanks to a wide range of additional elements – such as support rings (HL062B.3E) or drainage elements (HL160/HL161) – it can be adapted to conventional, inverted, ventilated or green roofs. Socket connection DN75/110 or the use of a compensating socket of the HDPE welded system facilitates integration with the existing sewage system. This means time savings and the ability to quickly adapt to the specifics of a particular project for installers.

Functionality and reliability in one

The self-regulating heating set provides not only protection against freezing, but also maintains an optimal temperature around the inlet, which increases its efficiency. A water flow rate of 3.70 l/s guarantees efficient drainage even during heavy rainfall. The solid construction made of polypropylene and the high-quality materials used in production ensure long-term reliability and minimize the need for maintenance. The stainless steel drain grate is resistant to loads and corrosion, which translates into an aesthetic appearance and long service life of the device.
