Gravity roof inlet, heated 230V DN125 vertical with leaf basket and PP collar for welding with TPO (FPO) membranes based on polypropylene or for gluing PE vapor barrier foils. HL62.1F/2

Roof gravity inlet with heating function

This vertical roof inlet DN125 is an effective solution for gravity drainage of roofs, especially in areas prone to freezing. Equipped with a self-regulating heating set powered by 230V, it prevents ice formation and ensures continuous water drainage, even at low temperatures. The design with a leaf basket minimizes the risk of clogging and facilitates maintenance.

Design and application

The inlet has been designed with versatility in mind – thanks to a wide range of additional elements (supporting and drainage rings of the HL350 or HL65 series), it can be adapted to various roof layer systems: traditional, inverted, ventilated and green. The collar made of polypropylene (PP) allows for a tight connection with TPO (FPO) membranes or gluing of PE vapor barrier foils. The possibility of a DN125 socket connection or the use of a compensating socket of the HDPE welded system ensures easy installation and integration with existing infrastructure.

Performance and advantages

• High flow rate: Provides efficient water drainage – up to 10.75 l/s, which translates to reliable operation even during heavy rainfall. This is more than competitive solutions offer.
• Universal mounting: Compatible with various types of waterproofing (PP, TPO/FPO, PE) and water drainage systems (DN125, HDPE).
• Clogging protection: The leaf basket effectively stops impurities, minimizing the need for frequent cleaning and maintenance.
• Anti-icing: Built-in heating set (10-30W) eliminates the risk of ice formation in the drain, ensuring continuous operation throughout the year.
• Durable construction: Made of high-quality polypropylene (PP), resistant to weather conditions and mechanical damage.
• Compliance with standards: Meets the requirements of EN 1253 standard, guaranteeing safety and reliability of use.
