We are capable to provide the full rainwater complete system with high quality material which including the Conventional Rainwater Drainage system, Siphonic Rainwater Drainage system and Rainwater Harvesting for any projects.
The implementation of fully automatic rainwater harvesting system to make the collection of rainwater easier to reuse in irrigation systems, WC System & other non-drinking uses.
Our system is perfect cooperation in terms of pipework’s' design and supply which capable to provide a hybrid backup system for any buildings by our BESSTEM Conventional Rainwater Drainage System.
BESSFLOW -- RAINPLUS requires a lower number of roof outlets and allows a substantial reduction in pipe diameters and quantities when compared to conventional systems.
The roof outlets are connected to single horizontal collector pipes that are fitted without gradient fall and the downpipes are positioned anywhere along the building perimeter, thus avoiding any interference.
When in operation drainage pipes flow at 100% full bore and high velocity. Therefore draining speed is greater resulting in the self-cleaning action of the pipework.
Construction programmes are accelerated due to reduced installation times moreover. Less groundwork is required due to the reduced number of embedded pipes.
Complete control over downpipe location and absence of embedded pipes causes increased design flexibility of the siphonic system.
The system is covered by warranties which guarantee against defects in design, installation, materials and workmanship up to Ten (10) Years upon commissioning
Wide range of diameters from DN 50 mm to DN 315 mm, available in SDR 26 and SDR 33 ; included access pipes, elbows, reducers and
Resistance to intermittent discharges at temperatures as high as 950C. High resistance to extremely rigid temperatures as low as -400C.
Durable, excellent abrasion resistance and mechanical strength. The pipes are stabilized to reduce dimensional variation and contain carbon black for UV light resistance.
Possibility of prefabrication to reduce assembly time on site possibility of creating special pieces for particular applications and solution.
High chemical resistance to substances dissolved in civil and industrial waste waters.
Wide range of transition fittings for connection to other waste systems such as Cast Iron, PE, PP, PVC.
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.
Butt-welding machines could weld up to 315 mm diameters. This process is extremely useful for the prefabrication of system parts that are then installed and connected on site using the other numerous jointing methods.
Thanks to the use of electrofusion couplers that are available in 50 mm diameters to 315 mm diameters, all system parts can be prepared. A method that guaranteed rapid, uncomplicated and extremely reliable welding against any installation situation.
