Product Datasheets
A quality made system
The Rainplus® siphonic system is made up of roof outlets, pipe clamps and other clamping accessories, Valsir HDPE pipes and fittings, a software for 3D design and extremely professional computations.Valsir HDPE pipes and fittings are manufactured according to EN 1519 and have been approved to many standards worldwide (CSTB, IIP, KIWA, SKZ, ETA, Lloyd’s Register, etc.).
The light weight and wide range of pieces available make Valsir HDPE the ideal solution for the construction of siphonic drainage circuits.Valsir HDPE also offers great installation flexibility thanks to the various jointing methods, such as butt-welding and electrofusion.
CHARACTERISTICS OF EXCELLENCE
The advantages of Rainplus®
- Cheap. When compared to conventional systems, Rainplus®requires a lower number of roof outlets and allows a substantial reduction in pipe diameters, in the number of fittings required and in the number of downpipes: this results in savings of up to 80% on vertical pipes and from 20% to 30% across the entire system.
- Space saving. The roof outlets are connected to single horizontal collector pipes that are fitted without fall and the downpipes are positioned anywhere along the building perimeter, thus avoiding any interference.
- High performance. When in operation drainage pipes flow at 100% over the entire system. Draining speed is therefore greater resultingin the self cleaning action of the pipework.
- Sustainability. The ease in directing pipes to storage tanks makes the collection of rainwater easier for reuse in irrigation systems, fire ponds and tanks for non-potable uses.
- Time and labour saving. Construction programmes are accelerated due to reduced installation times moreover. Less groundwork is required due to the reduced number of embedded pipes.
- Increased design flexibility. Complete control over downpipe location and absence of embedded pipes causes increased design flexibility of the siphonic system.
- The Valsir Rainplus® system and HDPE are produced with completely recyclable materials which can be recovered at the end of their useful life. The production processes employed are energy efficient and have reduced impact. Valsir has adopted the Green Building principles in terms of respect for the environment and conservation of resources, pipes and fittings are in fact certified by the prestigious Singapore Green Building.
