Effective swimming pool water disinfection
Grundfos and AlldosGrundfos offers a full range of pumps and pumping solutions with more than 170.000 product variants to choose from. Since five years, Grundfos is also involved in the dosing area. The acquisition of Alldos, a German company, provides Grundfos with a wider product range. Alldos has almost 40 years of experience in the dosing area and therefore great amount of know-how in this market segment, especially in disinfection technology.
Chlorine gas - efficient and economic disinfectionThe chlorine gas disinfection system is up to any situation. Our products and systems are designed for safe functioning and a long service life. They comply with the highest safety standards. All our system components are perfectly coordinated with each other. If they are used as a complete package, they function in synergy with original spare parts and know-how of our service team to ensure safe and reliable processes.
Hypochlorite - safe disinfection for small poolsSodium hypochlorite is used mainly in water circuits where it is not expedi-ent to use chlorine gas due to low circulation rates - in small pools, diving basins or whirlpools for example. In the past, complex design measures have been necessary to ensure trouble-free dosing of the degassing medium sodium hypochlorite. We have solved this problem through our innovative Plus3 system which is also ideal for very small capacities

Perfect measurement and control
The individual components fo the disinfection systems can only work to optimum effect if they are controlled by compatible, higher-level electronics. Grundfos and Alldos offer a complete range of measuring systems for all kind of disinfection installa-tions.
Measure and control with Conex or Aquaserver With those two systems you can measure the chlorine diox-ide concentration, the pH value, the temperature and with Aquaserver DIP also the ORP in your swimming pool and and use this information to control the chlorine content and the pH value of the swimming pool water.
The Aquaserver DIP and Conex DIA-2 measuring and control are very easy to operate, only four operating keys are needed to con-trol and change the selection menu.
To accurately measure the chlorine content and pH value in swimming pool water, the compact systems combine two power-ful componenents – the pressure-proof chlorine measuring cell and the Aquaserver DIP or Conex DIA-2 amplifiers.
The measuring cell continuously determines the exact content of disinfection agent and simultaneously measures the pH value. Combined with Aquaserver DIP, it also checks the redox potential according to DIN 19643.
