In principle syphonic drainage is a very simple process.
How does siphonic roof drainage work.
Despite what its name may suggest the process of syphonic drainage does not actually involve the syphoning of water at all.
Hydromax siphonic drainage operates from natural hydraulics inducing a negative pressure in the piping system through the vertical displacement from roof to discharge position.
The water is sucked or siphoned from the roof down into the drain at high velocity.
Traffic free roof areas which are no larger than 150 m2 such as production buildings hangars or sports stadiums are suitable applications for siphonic drainage.
Instead syphonic drainage technology employs the use of a gravity induced vacuum pump to remove water at high velocity from multiple roof drains at once.
The fullflow system allows architects consultants and contractors alike to specify a lower number of roof outlet drains and have them flow into a single downpipe.
Siphonic systems are the best solution to commercial roof drainage in buildings large or small new or old.
When the siphonic drainage system works at full capacity the siphon effect is triggered resulting in a driving force that is proportionate to the height of the roof and the end of the circuit which is typically located at ground level.
A hydromax siphonic roof drainage system utilises the full height of the building to provide the energy to create a powerful siphonic action.
This pump requires no external power as it is activated by rainfall filling the drain beyond its anti vortex plate at which point air flow to the pipe is cut off.
Unlike traditional roof drainage which is designed to flow part full a syphonic system operates at full capacity when water is sucked or syphoned from the roof down into the drain at high velocity.
The main principle is that water is sucked or siphoned through rooftop outlets where baffle plates restrict the inflow of air into the system and this allows the system to run at full capacity.
Several of these drains tie into a horizontal collector that is routed to a convenient point where it transitions into a vertical downpipe.
Syphonic drainage systems are designed to flow partially full hs roofclad s syphonic gutters and drainage systems operate at full capacity meaning water is syphoned from the roof and then down into the drain at high speeds.
How does it work.
