Heated gravity drain for roofs or terraces with pedestrian traffic, 230V, DN75 vertical with stainless steel grate and bitumen collar for welding to roofing felt. HL62.1BH/7

Roof and terrace drainage with heating system

This vertical gravity inlet, designed for use on roofs and terraces with pedestrian traffic, provides an effective solution for water drainage. Equipped with a 230V heating system, it prevents ice formation and ensures reliable operation throughout the year. This makes it ideal for areas exposed to low temperatures and snowfall.

Construction and installation

The inlet is characterized by a solid polypropylene construction, ensuring durability and resistance to weather conditions. A bituminous collar allows for a tight connection with thermal welding waterproofing layers, minimizing the risk of leaks. A stainless steel grating guarantees corrosion resistance and long-lasting aesthetics. The ability to adapt to different roof layer configurations thanks to additional elements (supporting or drainage rings of the HL350/HL65 series) is a major advantage for professionals. Connection to the installation is made via a DN75 spigot connection or an HDPE compensating socket.

Performance and application

The inlet provides a water flow rate of 6.00 l/s, guaranteeing effective drainage even during heavy rainfall. A self-regulating heating set (10-30W) maintains the surface temperature of the inlet above zero, preventing water from freezing and ice dams from forming. This is particularly important in areas with high snow loads. A wide range of additional equipment allows the solution to be tailored to the specific needs of each project – from simple roofs to complex structures with different insulation layers.
