Quadro-limit – characteristics

5

For typical head of ½ up to 3 ½ layers Rigofill inspect (0.35 – 2.33 m)

Flow range: 0.5 – 55 l/s

Integrated in the modular Rigofill system – no separate shaft after the boxes

Easy installation – shaft „ready-to-use“ with integrated throttle unit

All units custom made, project related

Reduced overall project costs

Quadro-limit – features and benefits

6

Summing up:

High flow rates in all modes of operation

Reduces emptying time to a minimum

Minimises the required storage volume by up to 30%

Self-activating – does not require external power supply

Openings are larger than eqivalent orifice – highly reduced risk of blockage

Flush Flo: Self cleaning effect

Manufactured from stainless steel, no moving parts – longlasting construction

Requires minimum maintenance – allows high pressure jetting

Performance proven worldwide since the 1980‘s

The Quadro-limit in your country

- It will help the Rigofill-system beeing

nonexchangeable once beeing in the design

- The specific flow chart will be delivered for

each project.

Depending on your countries way to calculate

the basin volume, you might need additional

information.

Fränkische has to know those to be prepared!

Test Material: Millisil W4, fraction up to 190 µm (= 0.190 mm),

officially used for DiBt assessment

Sedi-pipe is designed to also capture these small fractions

These are the biggest particles which could in theory enter

to the boxes

How it works: Jetting philosophie of the Fraenkische Rigofill

inspect system

1. Pre treatment only allows very fine particles to enter to

the system

2. Fill the system with water

3. Use the guided rotating spray nozzle with both 45° and

90° angles for spraying

4. Get the seddled solids into suspension

5. Suction

Integrated Stormwater Management Systems

- Rigofill, the complete system out of one hand.

- Your consulting brings the system into the design

and the tender phase

- The single components of the system make the complete

system nonexchangeable

SEDI-pipe, Quadro-control, Quadro-limit keep our system

in the project through the tendering phase …
