De CombiCompact is developed for the smallest spaces and POU (Point of Use) solutions. Therefore it is ideal for protecting a single boiler or other equipment. The CombiiCompact has an integrated filter mesh to catch impurities. Advice is to clean this filter when you replace your dosing cartridge or earlier when you notice reduction in flow rate.

PrefilterPLUS has a separate XL pre filter to catch impurities, ensuring these will not enter your system. We advise PrefilterPLUS as POE (Point of Entry) system for a complete home. It is installed directly after the main stopcock.

Yes, CombiCompact is very capable of treating all the water for your whole house. Only bear in mind that the pre filter mesh might need an extra clean when your water contains I high volume of inpurities (often showing by water coloring brown).

Polyphosphate is a food-grade (consumable) product and approved by the WHO and FAO. It is being used in the food processing industry for cheese, meat, wine and other products. It is 100% safe and suitable for the treatment of (drinking) water.

NoCalc® does not remove Calcium or Magnesium from the water as these minerals are crucial to the human body (bones). In several countries water companies have to make sure that Calcium is not eliminated or removed from their systems. NoCalc® seals the Calcium so it cannot stick on the inside of pipework, equipment or on sanitary ware. By treating water in this way, your body will always receive enough of these important minerals. You will have the benefits of Calcium, but not the deposits.

De PrefilterPLUS versie heeft een aparte en extra grote prefilter unit om vuil uit het leidingsysteem te weren. PrefilterPLUS wordt geadviseerd, en is het meest geschikt, als Point Of Entry systeem (voor een complete woning of bedrijfsruimte) en wordt geïnstalleerd direct na binnenkomst in een woning of bedrijfsruimte (meestal direct na de watermeter)

No!…..NoCalc removes the Calcium by a patented dosing system. This way Calcium remains available for consuming. The seal will naturally be broken down by the human body when drinking water. NoCalc® is food grade, 100% safe for drinking water and environmentally friendly

Yes! The NoCalc® method is a completely safe way to treat (drinking) water and is safe for human consumption according to the WHO* and FAO* recommendations and in accordance with the international norm for drinking water to the EC regulations, standard (EN 1208) *FAO / WHO (Food and Agriculture Organization of the United Nations / World Health Organization).

The 50 micron NoCalc® Prefilter ensures that all the little particles will be removed from the water before the NoCalc® treatment. It also guarantees the optimal working of the dosing systeem (will not get blocked) For this reason we combined the two elements in one NC39000 Starter set. This way everything you need comes in one package (including universal connectors)

When water dries up the Calcium will be available again. The reason for this is that the Calcium has to remain available for the human body (crucial for the bones). The Calcium however will not stick to surfaces and can be removed very easily (even with a dry cloth) due to the NoCalc® seal which has been formed during the treatment. This way it will save a lot of cleaning work..

Unfortunately NoCalc® cannot clean your kitchen and bathroom for you. However you will experience the difference! You will notice that cleaning is easier and quicker. The NoCalc®protection film will make sure no limescale can stick and can be removed within seconds, leaving you more time for other activities.

NoCalc® has many advantages compared to others: Easy fo fit and no electricity required. NoCalc® does not waste water (other systems often have to flush regularly (regenerate) which flushes away many litres of valuable (drinking) water. NoCalc® is environmentally friendly, uses no salt and is low in purchasing and maintenance cost. Please look for all advantages on the other pages of our website.

No, NoCalc® is easy to install. We advise to use a qualified plumber who should be able to install the complete system within the hour..

NoCalc® is available through a network of professional dealers:  Please feel free to contact us for your nearest NoCalc® dealer.

One replacement dosing cartridge will treat approximately 35,000 litres (35 m3) of water. This is an everage of only one cartridge per person per year. In a household of four people the cartridge will need replacing every three months. On registration through this website we can remind you when it’s time to replace your cartridge.

You can check the level of the cartridge visually.. The housing and the cartridges have been made transparent for this purpose..

Yes, the new cartridge will immediately create a new solution and will work instantly. The powder will shrink and the level of the powder will drop while the system creates the dosing fluid. You might experience some mixed water/air coming from your taps during the first few litres. This is normal.

After 40,000 litres, the dosing which treats the calcium will be used.. Other components (for forming a protective film on the inside of your pipework) can last longer. To keep your system working to the maximum we advise you to change out the cartridge after 40,000 litres.

Of course the quality of your water is the most important factor. We advise to check your prefilter every month visually and to clean it when needed. We do strongly advise to clean your prefilter cartridge on replacing the dosing cartridge (after 35,000 litres) or every three months. TIP: If you choose to have an extra Prefilter cartridge you can use this as a replacement and clean the dirty cartridge by simply putting it in the dishwasher.

Also at higher temperatures NoCalc® protects against the build up of limescale. Elements in boilers and heating equipment (60-65 Degrees Celcius) will be protected. At temperatures above 100 Degrees Celcius the effectiveness will be reduced as water will become steam. This way the Calcium will become visible again, however it can be removed very easily as it will not stick to surfaces due to the NoCalc® treatment method.

NoCalc® kan gemonteerd worden in alle leidingsystemen met een AANVOER temperatuur van 1 tot en met 40 graden Celcius. In vrijwel alle gevallen van heet water AANVOER is de temperatuur hoger dan 40 graden Celcius. NoCalc® kan echter altijd normaal in uw koud water aanvoer gemonteerd worden waardoor uw huishoudelijke apparatuur toch wordt beschermd (uw waterverwarmende apparatuur wordt sowieso altijd met koud water aangesloten) en u ook de andere voordelen van NoCalc® ervaart.
