The new EN152288 parts 1 and 2 state that all new pools must be dye tested to check circulation on commissioning and then repeated every five years.  Our Aqua Couleur is a safe and easy way to test circulation.  For prices and more information see our Aqua Couleur page on this website or contact our Head office on 01526 322214 or email This e-mail address is being protected from spambots, you need JavaScript enabled to view it

Dosing equipment

Flowtab II is a fully automatic calcium hypochlorite dosing system, which is compatible with all the leading hydrated calcium hypochlorite tablets.  Flowtab II has been engineered and designed to dispense the calcium hypochlorite tablets in a safe, economical and trouble free manner.   

Flowtab II is suitable for the private or public sectors, potable or swimming pools in either single or multiple applications and is designed to manufacture a constant chlorine solution ondemand, thus, eliminating the need for large storage tanks of solution and the use of mixers.  Operators are only required to maintain the supply of hydrated calcium hypochlorite tablets within the hopper.   Flowtab II is unique as it is the only calcium hypochlorite dosing unit that offers a preset chlorine solution of a constant strength of between 0.1% and 1%. Chlorinator N.X is a dose measuring device that continuously adds the correct amount of chlorine to the pool water.  Simple, effective and easy to use, this unit is very popular with pool plant staff.  The dose-measuring device is connected to the filter pumping system of the swimming pool.  The device itself is not fitted with a pump but makes use of the water circulation caused by the filter pump.  Malfunction is minimal because the device does not have any moving parts.  The Chlorinator N.X is suitable for pools with a water capacity ranging from 200 to 800m3. 

JAK Water Systems offer a variety of controllers andmonitoring equipment, which we would be very happy to discuss the equipment most appropriate for your pool type, size and environmental conditions.
