Emergency roof inlet gravity DN125 vertical, heated at 230V with overflow with adjustable height 28-68mm and PVC flange HL62.1PSAFE/2

Emergency roof drainage – reliable protection against the effects of extreme rainfall

This emergency vertical roof inlet, designed for gravity drainage, is a key safeguard for the building in situations where the main rainwater drainage system cannot cope with excessive rainfall. Its design allows for effective drainage of water from the roof, minimizing the risk of leaks and structural damage. This inlet is particularly important in regions prone to heavy rainfall or sudden weather changes.

Design and functionality

The inlet is made of high-quality PP plastic, which guarantees its durability and corrosion resistance. It is equipped with a self-regulating heating set powered by 230V, which prevents water from freezing in winter and ensures continuous system functionality. An overflow with adjustable height (in the range of 28-68mm) allows for precise adjustment to the permissible water backwater height, which is particularly important under various weather conditions and roof configurations. The drainage grate with a diameter of 262 mm effectively stops leaves and other debris, preventing the system from clogging. A PVC collar ensures a tight connection with the roofing material.

Advantages for installers and users

• Versatility: Compatible with DN125 spigot connections and compensating sockets of HDPE welded systems.
• Easy adjustment: Smooth, stepless adjustment of the cap height facilitates installation and adaptation to the specifics of the roof.
• Freeze protection: The heating set ensures reliable operation even at low temperatures.
• Effective filtration: The drainage grate minimizes the risk of clogging the system with contaminants.
• Safety: The emergency inlet is an independent water drainage system that works in the event of a failure of the main drainage system.
• Compliance with standards: The product meets the requirements of ÖNORM B2501-2015, which confirms its high quality and safety of use.

It is important to remember that the water drained through the emergency inlet should be directed to the area adjacent to the building and must not be connected to the main roof drainage system. This solution ensures independent operation and protects the main system from overload during extreme rainfall.
