2 Harness the power of Vortex

3 Gatic Vortex has been deveoped to bring the benefits of advanced fuid dynamics to the contro of surface and waste water in a wide range of situations. More than 35 years of reevant professiona and speciaist experience in the fied of storm water attenuation, sewerage system design and vortex technoogy, mean our designers and engineers are we equipped to provide highy capabe and competitive products, as we as sound advice to the industry. Vortex Fow Contro systems (VFCs) have now been successfuy instaed in their thousands a over the UK and throughout Ireand. the hydrauic head has risen sufficienty for it to provide enough energy for the iquid to rotate consistenty. When the fow rate reaches such a eve, the iquid rotates at high veocity around the inner face of the contro, resuting in a high energy, air fied vortex. The air core occupies the majority of the outet of the contro with the fow exiting the device from around the outer edge as a spray rather than a jet. Vortex fow contros therefore have a much arger cross-sectiona area than conventiona fow contros. Consequenty, they are much ess prone to bockage. How does it work? The design aows the fow to enter tangentay. At norma and ow fow rates, the iquids pass straight through the contro. As the rate of fow becomes greater, the increase in hydrauic head (and hence energy) causes the iquid to attempt to rotate around the inner face of the contro. This resuts in a brief transition period unti OUTLINE PIPE AIR CORE VORTEX FLOW PATH INLET Speciaised Engineering. Specia Advice.

4 Bespoke Vortex systems to suit any appication Every Gatic Vortex project is individuay buit for its appication. Since a of our fow contros are bespoke fabricated, they can be made to fit into any type of chamber, tank or system. We are we aware of the effects that deveopment has had on the UK s water tabe and natura soakaways and aways take these considerations into account in formuating our recommendations. OUTLINE PIPE Gatic has a range of VFCs at its disposa to aow the most effective configuration to be depoyed for each situation. In deciding the size and type of VFC that wi be best suited to provide the fow contro that your project cas for, we use our experience to pan and contro the materias, time and abour costs, ensuring the most efficient and cost effective outcome. Features and options AIR CORE INLET VORTEX FLOW PATH SW contro units Typicay referred to as Snais, these contros are generay ony used in surface water systems as a sump is normay required, due to the outet being higher than the inet. Fow range: itres per second CB contro units These can be used in surface water systems where SW versions are physicay too arge. Aso used in fou or combined appications. Fow range: itres per second CS contro units Used where other designs cannot be accommodated due to their physica size. Fow range: itres per second We have deveoped a range of designs, each with unique characteristics which, combined with additiona features and options, enabe us to meet any brief. Our devices are typicay fabricated in 10 gauge 3mm 304 grade stainess stee to the reevant British Standards. (316 grade is aso avaiabe.) Stainess stee is far superior to the pastic often used for VFCs. It wi not corrode and is resistant to turbuence and abrasion. Life expectancy of the unit is ikey to exceed that of the system to which it is instaed. Post instaation maintenance is negigibe. Bockages are practicay unheard of and the drain-down/bypass mechanism is operated remotey from ground eve. Shoud a bockage occur, the mechanism aows drain-down without over pumping or bypass penstocks and extra pipework.

5 Vortex fow appications The ist of appications for Vortex Fow Contros woud have to incude virtuay anywhere of an area big enough for surface water reguation and disposa to be ikey to become an issue. In today s changing weather environment, with severe weather events becoming ever more frequent, the demand for effective contro can ony become more pressing. Beow are a few current exampes. Major infrastructure projects. Contro of surface water run off from: Housing deveopments Industria deveopments Infrastructure deveopments Land drainage As part of food and poution aeviation schemes within: Existing sewerage systems River networks Urban deveopment and andscaping. Construction and redeveopment. Fow baancing in: New and existing sewerage systems Sewerage treatment works Potabe water treatment pants Contro of pass-on fows from: Combined sewer overfows Storage tanks Reservoirs Swaes Reservoirs, and drainage and sewerage contro.

6 Technica information and engineering back-up At Gatic, we take pride, not ony in the overa exceence of our products but aso the scope and standard of our speciaised engineering back-up and advice. Since a our systems are bespoke designs, unusua and probematic situations, requiring a unique Vortex Fow Contro are nothing new to our engineers and designers. Exampes of siding orifice pates and fow restrictors. We have a huge fund of experience and a vast inventory of equipment from which to tease the perfect soution. However, we pride ourseves on the impartiaity of our advice. If a VFC instaation is inappropriate and wi not successfuy provide the answer to your water contro and disposa probems, we wi happiy point you in other directions more suitabe to your requirements. Technica data Vortex Fow Contro design and instaation is a highy speciaised and technicay demanding business and, athough some of our customers ike to be invoved in the detai to a greater extent than others, many prefer to brief us thoroughy, approve the pans and figures we present and te us to get on with it. Typica instaation drawings for Gatic Vortex Fow Contros. At Gatic, we re happy to pay it either way, suppying you with as much or as itte technica information as you desire. On this page you wi find exampes of typica instaation diagrams and opposite are fow charts and graphs for a sampe SW Vortex Fow Contro unit.

7 Additiona features No moving parts. Sef-activating. No externa energy requirements. Very resistant to abrasion and corrosion. Other materias such as Grade 316 stainess stee are avaiabe when necessary, (eg. for use with sat water or chemicas). Individuay designed. A of our fow contros are individuay cacuated and fabricated to the miimetre to achieve maximum efficiency. We aso design our fow contros to suit every individua situation to work with a types of systems od or new. Savings in time and abour due to fexibe instaation methods. Unique head/fow reationship can produce savings in storage voumes. Throtte pates. Orifice pates.
