ALL AT THE TOUCH OF A BUTTON!
Dosing and control pumps are the unsung heroes of the pool industry. They are reliable, efficient and certainly unglamorous but it would be wrong to take these automatic systems for granted. Once only an option for commercial installations, today’s pool owners want reliable dosing and control systems not only to take stress and hard work away, but also to ensure pool water is perfect at all times

nsung heroes, backroom boys, whatever you wish to call them there is no
doubt that the automatic control systems that ensure lovely and hygienic swimming pool and spa water are the real workers when a pool is run without too much being done by way of manual intervention. As with many automated pool items, these technical whiz kids started life firmly ensconced in the plant rooms of commercially run facilities, but today’s high tech leisure world now reaches extensively into the domestic market and manufacturers are recognising the need for cost effective home-use systems. The benefits of automatic control and dosing in domestic or commercial; pool or spa facilities are as clear as the water they treat and maintain. When a pool is dosed automatically by means of the technical bells and whistles that regulate automation it ensures that the chemicals are distributed accurately, safely and economically. Removing all guesswork and ensuring that even under very heavy usage or unexpected duress, disinfection remains guaranteed. Today’s technology offers a virtually maintenance free operation but as many of the experts agree, there must be some human intervention to ensure all is running smoothly.
The dosing pumps are whisper quiet in comparison to their predecessors so giving greater scope as to where they can be installed. The only thing these modest and murmuring systems shout about are the fact that they are suitable for most budgets, on the domestic and commercial scale, and when all things are considered these control features should be an automatic choice in any plant-room.
GAFFEY EXTENDS ITS RANGE WITH GRUNDFOS LINK Gaffey Technical Services Ltd continues to extend and develop its range of controllers for which it has almost unrivalled experience. The family owned business provides specialist chemical dosing equipment and service to local authority and commercial pools throughout the UK. The 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 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 2.5 ml to 30 L per hour at an optimum price/performance ratio, so can help save on maintenance/running costs as well as stock/spares inventory. The Poolcontrol DYNAMICS water quality controller, with many sophisticated features as standard, offers 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.
SAFE DRIVING
Topline’s Martin Baulcombe takes up the story when he says: “All chemical controllers work in the same way, basically they are switches; they read the chemicals in the water and turn the pumps/feeders on or off. They will control the information that they are given, if the user inputs bad information the controllers will give bad control. This highlights the importance that the user knows how to take manual tests and interpret the results. Chemical controllers and dosing systems are not automatic in
