“There are many types to choose from and whilst automatic dosing was once firmly the domain of commercial installations, today’s sophisticated domestic pool owners quite rightly demand reliable dosing systems to ensure their pool water is perfect at all times whether they are home or away!”


balance via the Langlier index. All enabled via the BECSys for windows, vista-compatible PC software. This provides management with an intuitive graphical analysis tool, with full read/write access to all parameters this also enables contractors to monitor facilities remotely, reducing those expensive and carbon generating call outs.


Aquatrol’s model BECSys 5 is a richly featured controller based upon a proven design with many years of reliable field performance. Application features includ: • Patent-pending VFD control algoritham • Flow meter monitoring and display • Monitor total dynamic head of the circulation pumps


• Free and total chlorine measurements • Turbidity, TDS monitoring, display and control • Monitor chemical inventory levels • Auto-fill and much more


All accessible via easy to use dedicated front panel buttons for quick access to common operators, clear status and alarm indicators, plus on-screen help comments via the intuitive menus; something every one needs now and then. Aquatrol’s sound advice is to reduce the use of chorine and use control to minimise consumption and maximise benefits provided by a proven oxidising product.


A smart move


Gaffey Technical Services Ltd is reporting that some important new products are to be launched this winter that combine simplicity, versatility and quality. These new products offer trade suppliers the opportunity to rationalise their stock and assist end users in achieving optimum pool water quality.


Grundfos SMART Digital dosing pumps represent a big step forward in rationalising dosing systems. A brilliant idea from Grundfos, SMART Digital pumps can perform virtually all swimming pool dosing applications, so pools no longer need different models of pumps to perform separate tasks. Although supremely


Everything in one box Seko UK offers a broad range of dosing systems for both domestic and commercial pools. With their Pool Basic Series which is aimed at the domestic market, the company has developed a simple and reliable system made up of an industrial container that houses the dosing pumps and instruments thus making installation and maintenance easy whilst providing protection against unauthorised interference. The system benefits from peristaltic technology – low noise output, easy to use, low maintenance, protection against siphoning phenomena, avoidance of direct contact with chemical products.


versatile, they’re quick and easy to set up and use, with a self-explanatory ‘click wheel’ menu system to help operators. The pumps deliver high precision dosing from 2.5ml to 30l per hour at an optimum price/performance ratio, so can help save on maintenance/running costs as well as stock/spares inventory.


Also new this winter is the dinotec Poolcontrol DYNAMICS water quality controller, with many sophisticated features as standard, offering excellent value for money. A versatile compact controller, it offers easy but intelligent control of pH, Redox, potentiostatic free chorine control and temperature measurement. Also in-built is dinotec’s ASR electronic sensor cleaning technology, regarded as one of the most accurate and reliable methods on the market. Single point pH calibration, which is simpler for operators to use than standard 2-point calibration, and remote monitoring BMS connections are also included as standard. Andrew Gaffey at Gaffey Technical Services Ltd says: “We always aim to support pool operators and trade suppliers by offering innovative products that are reliable and easy to use. These new models offer the versatility and accuracy that can help the end user achieve better water quality and economy, whilst significantly reducing the spares inventory and stock holding costs for both operators and the pool trade alike.”

Peristaltic pump proves perfect partner Although only introduced in 2009, the Verderflex Aura peristaltic dosing pump is already making waves. This model is ideal for low flow, high pressure dosing applications and the facilities that are already benefiting from its introduction are leisure centres, swimming pools and saunas. The Aura is proving a superior alternative to reciprocating piston pumps thanks to its unobtrusive design, silent running and immunity to off-gassing and vapour locks.


Typical early users include a leading supplier of engineering services to the swimming pool industry in the UK. Its interest is in the low, constant flow of polyaluminium chloride (PAC) and to introduce essence into steam rooms, again a low dosing application. And following a successful trial at a major London health spa, the Verderflex Aura will be replacing existing piston pumps that service its spas and wet rooms. For this user, performance and price were the deciding factors. The Aura pump features an easy to access pump head with a simple to use tube load facility
