Baffle and prevents air and debris from entering the piping system at full flow allowing the pipes to completely fill up with water.
How do siphonic roof drains work.
A constituent part of the hydromax siphonic system is the special hydromax siphonic roof drain.
The piping system is empty prior to a storm event occurrence.
A siphonic roof drain has a special insert that acts as an air baffle and anti vortex vane such that only water is drawn off of the roof not air.
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.
Despite what its name may suggest the process of syphonic drainage does not actually involve the syphoning of water at all.
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.
However that isn t always enough.
The water is sucked or siphoned from the roof down into the drain at high velocity.
Those roofs benefit from siphonic drainage systems.
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.
So interior drains can be used in combination with scuppers which drain water at the edge of the roof.
Baffle plates inserted in the outlets restrict air entering the top of the system which when combined with carefully sized pipework causes the system horizontal and vertical to run full.
In principle syphonic drainage is a very simple process.
The hydromax drain outlet is designed so that as soon as the rainwater reaches the hallow deth to the underside of the inducer plate the unique inducer prevents air ingress into the pipework as a first step towards making the system run.
A hydromax siphonic roof drainage system utilises the full height of the building to provide the energy to create a powerful siphonic action.
A collection of elements combine to create the hydromax siphonic roof drainage system.
Several of these drains tie into a horizontal collector that is routed to a convenient point where it transitions into a vertical downpipe.
Siphonic drainage is actually very simple in principle and all systems work in exactly the same.
By contrast a fully engineered siphonic roof drainage system contains an anti vortex plate that acts as a.
