The leakproof connection is ensured by means of butt welding or using electrofusion couplings. Under the roof, the Pluvia roof outlets are connected to the installed discharge stacks made up of PE pipes. Thanks to the negative pressure system, only few discharge stacks are required.

A siphonic roof drain has a special insert that acts as an air baffle and anti-vortex vane. Unlike traditional roof drainage systems, a siphonic system is designed to operate with the piping completely charged with water during a rainstorm. When the condensate is drained from the ventilation unit, it passes the drain pipe through the flexible. The syphon must be connected to a drain pan pipe 18 mm. The emergency drainage springs into action as soon as the rain exceeds the capacity of the Pluvia system – i.e. Developed by two engineers in Finland, siphonic roof drainage made its first appearance in Europe in 1968. The hydraulic syphon kit for water heat exchangers SFK 20x32 is designed for condensate drainage from heat exchangers and coolers in ventilation and air conditioning systems. The main drainage system can drain around 40,000 litres of rainfall per minute. Around 140 roof outlets with a capacity of 14 litres per minute as well as approximately 3,000 metres of Geberit PE pipes are required for the above-mentioned roof surface. DRAINAGE SYSTEMS RAINPLUS® AND CONVENTIONAL ROOF DRAINAGE SYSTEMS The systems used for roof drainage: conventional gravity roof drainage system (air/water flow) siphonic roof drainage system (full bore flow) Also siphonic systems are based on gravity effect but this designation is used for an easy distinction. A closed water column thus forms in the pipes, causing the water to be quickly and efficiently suctioned off. So how does it work? While Pluvia works like a conventional roof drainage system during light rainfall, the pipes fill up rapidly and without air pockets when there is heavy rainfall. (Duration: 11mins) Syfonic Roof Drainage. Architectural flexibility in building design that no other system can match. The Pluvia drainage system from Geberit, which works on the basis of negative pressure, can easily handle such large volumes of water. Syfon Systems syfonic roof drainage system, designed and developed in Australia, equates to Lower capital costs. Although such events are rare, drainage systems have to be able to cope with such large volumes of rain.ĭesigned to cope with once-in-a-century periods of extreme rainfall During heavy rainfall, tens of thousands of litres of water per minute can pelt down onto an area of this size – and up to 75,000 l/min during a once-in-a-century period of extreme rainfall. When it comes to efficient roof drainage, the tried-and-tested syphonic roof drainage system Geberit Pluvia is a safe choice.Ī warehouse extension in Pfullendorf in south Germany has a roof area of 19,230 m2.
