Roof inlet gravity DN110 horizontal with insulated body, heated at 230V (10-30W) HL64.1BP/1

Efficient flat roof drainage with freeze protection

This gravity roof drain, designed for use on flat roofs and terraces with medium pedestrian traffic, combines high performance with additional protection against the effects of low temperatures. The insulated body design minimizes heat loss, and the built-in heating system (230V, 10-30W) effectively prevents ice blockages, ensuring continuous operation throughout the year. This is an ideal solution for both professional installers and building owners who value reliability and comfort.

Universal mounting and adaptation to different roof layers

The drain is designed for flexible mounting. The ability to adapt to different roof layer configurations thanks to a wide range of additional elements – support rings (e.g. HL062B.3E) or HL350/HL65 series extensions (e.g. HL160, HL161) – is a key advantage of this product. This ensures a tight connection with the waterproofing layers and easy integration with existing infrastructure. Compatible with DN110 spigot connections and HDPE welded systems, it offers wide possibilities for adaptation to individual project needs.

Solid construction and durable materials

The body made of PVC and polystyrene foam provides not only thermal insulation but also resistance to corrosion and mechanical damage. The stainless steel grate (137x137mm) set in a polypropylene frame guarantees durability and aesthetic appearance. The entire structure has been designed to ensure long-lasting and trouble-free operation even in harsh weather conditions. A flow rate of 3.70 l/s ensures effective water drainage even during heavy rainfall. It is worth noting the possibility of using different types of grates – from domed to flat – which allows you to match the appearance of the drain to the character of the roof.
