Series 49 DRAINJET with siphonic flow

LORO-X siphonic drainage systems with siphonic flow are operated with smaller pipe diameters and at the same time a higher drainage capacity thanks to the higher flow velocity. The high flow velocity in the hot-dip galvanised and additionally internally coated steel drainage pipe also increases the self-cleaning effect. The largest model in this series drains up to 100 litres per second. That corresponds to approx. 3000 m2 of roof area with only 1 drain!

Space-saving

LORO-X siphonic drainage systems with smaller nominal diameters are particularly space-saving compared to conventional drainage systems when several drains are connected to a collecting pipe under the roof to which only one downpipe is connected. The interior of the building can thus be used optimally.

Freedom

Freedom in planning: The collecting pipes of LORO-X siphonic drainage systems can be laid under the roof over greater distances without gradient from the position of the drains to the position of the downpipe. This provides maximum freedom in the positioning of drains and downpipe.

Rainwater harvesting

Ideal for rainwater harvesting: Large quantities of rainwater from several drains and large roof areas can be conveyed specifically to the position of rainwater use with a hydraulically optimised LORO-X siphonic drainage system without gradient and over long distances. 

Main and emergency drainage

The emergency drainage can also be calculated and implemented as an internal LORO-X siphonic drainage system on the basis of the so-called century rainfall intensity with discharge "into the open". The emergency drainage must not be connected to the collecting pipe of the main drainage, but must be led out of the building via a second pipe system. Alternatively, parapet drainage systems with siphonic flow are often used for the emergency drainage, such as the LORO-X ATTIKASTAR.

LORO-X calculation service

Siphonic flow systems require a project-specific hydraulic verification in which the dimensioning of the pipes and fittings is optimised on the basis of the pipe routing using special software. LORO offers the complete service from planning and calculation to delivery to the construction site from a single source.
