BLÜCHER® Drain Roof – siphonic

BLÜCHER® Drain Roof Siphonic drains and gravity drains

Owing to the siphonic plate of the drain, the pipe is quickly 100% filled, keeping air out of the system and allowing full bore discharge to induce a siphonic action resulting in higher velocities and greater discharge.

BLÜCHER® DRAIN ROOF SYSTEMS

BLÜCHER offers a stainless steel roof drainage system
suitable for:
• Flat roofs of all designs
• Downpipes from roofs of all designs
• Roofs with bitumen or single ply roof membrane
• Equally suitable for gravity and siphonic systems
BLÜCHER® roof drainage system comprises strong products which are capable of resisting impacts, corrosion as well as fire and require minimal maintenance.
Gravity roof drainage is used in traditional newbuild or refurbishment projects.
Siphonic roof drainage creates a flow rate approximately 3 – 5 times higher than in a gravity system. This means that a larger roof area can be drained by fewer
roof drains connected to one pipe string in smaller diameter
than that required for the gravity system.
It is BLÜCHER’s mission to provide a high-quality roof drainage system with roof drains easily connected to the BLÜCHER®
EuroPipe pipework system, offering the customer a safe roof
drainage system that minimizes installation time and ensures
high performance as regards
• High flow capacity
• Ease of installation
• Non-combustibility
• Long product life
• A1 fire approved

^ Fastening points only required on the building structure every 2.5 metres
^Can be installed easily using a hammer thanks to the universal tension wedges
^Fastening with electrofusion tape enables anchor points to be determined subsequently
^Ideal for lightweight roofs since there are only weak forces acting on the building structure.
