Nelsen Scale Prevention Systems

Nelsen Scale Prevention System Residential LineAvailable in 5 Residential sizes, 8", 9", 10", 12" & 13", Nelsen Scale Prevention System features Filtersorb SP filter media to first remove the already existing scale from pipes and heat exchanger surfaces (descaling effect) and further to protect the system from future formation of scale (scale protection effect).

Filtersorb SP is based on a completely new technology. In this process the chemical structure of scale forming minerals is changed. This technology is so effective that it requires a contact time of only seconds.

The media is used in an up flow system, therefore only an in-out head is needed. The media transforms the dissolved calcium carbonate (temporary hardness) into non-charged, neutral chemical bonds. These bonds are completely stable and cannot attach to any surfaces. The chemical bonds are rinsed away by the water flow. The size of the bonds is so small (in the range of nano-meters) that they can only be seen with a microscope. Therefore the effect is the same as if the water was free of temporary hardness (calcium carbonate). The chemical structures are heat resistant and do not fall apart.

Filtersorp SP works great in front of RO membranes. It keeps these membranes from clogging with calcium-carbonate. A preexisting membrane's efficiency is improved after only 10 days if calcium carbonate was the reason for the blocking.

Everything is Included!Everything is included! There is nothing else that has to be added unless you want to dress up the package with a tank jacket. Included in 8", 9" and 10" systems - Filtersorb SP Filter Media, Enpress Mineral tank featuring the Vortech bottom distribution plate, "C" Series in/out head, "C" Series Bypass, 1" NPT PVC -plumbing adapters, 1" x 10" "Big Blue" housing with GAC pre-filter with mounting bracket.

12" and 13" systems include a 20" Big Blue Housing and GAC Pre-Filter in lieu of 10" housing & filter. 

For applications that need a higher flow rate or feed water with higher than 25 grains hardness, give us a call! We can engineer a system to meet your needs!
