The following tests and measurements was taken on a common Neodymium
Magnet
design. This design is US made with Chinese Copies also on
the market. First we examine the mechanical aspects of
this design and then measurements were made looking for the peak
flux density. While the large Neodymium magnet does provide
a boost in flux density over the GMX design, it has three major
flaws in it's design. The main problem is there is no way to
firmly attach the units to the pipe and the magnet faces are not
protected from Galvanic corrosion, and it has poor magnetic
performance . This design, just like the GMX does not focus
the magnetic field inside the pipe as the Trentatron design does.
It also fails to shield the powerful magnetic field from it's
surroundings. Not only is this field not being contained
inside the frame, external magnetic fields from nearby electrical
devices are also allowed to interfere with the field from the
magnets.

This design
has no lateral stability as shown in the left hand picture.
Nothing prevents the unit from being knocked off of the pipe
with the slightest push. |
Trentatron
attached to pipe with Ty wraps with adhesive
tape to protect the magnet faces from Galvanic Corrosion. |

Neo Sof with 1/2" Copper Pipe |

The following tests
and measurements was taken on Neo Sof type units
installed on different sizes of copper and PVC pipe.
Measurements were made looking for the peak flux density
inside the pipe. Comparisions are made to the
performance of corresponding Trentatron unit.

Neo Plus Rated for 20 GPG |
Neo Max Rated for 60 GPG |
Trentatron TAT-1
Rated for all water Conditions |

As you can see the
Trentatron design out performs both versions of the Neo Sof
design. Our magnets are the same size as the Neo Plus
unit but our units out perform the Neo Max units which employ
thicker magnets (1/2" vs. 3/4")

Rated for 20 GPG |
Trentatron TAT-2
Rated for all water Conditions |

As you can see the
Trentatron unit closely matches the performance of the Neo
Plus Large Pipe unit. But there is one big difference
here, while the Trentatron magnets are not as thick as the Neo
Plus unit they are twice as wide as the Neo Plus magnets.
If the pipe is 2" wide, you need a two inch wide magnet.

Neo Max Large Pipe
Rated for 60 GPG |
Trentatron TAT-21
Rated for all water Conditions |
|

As you can see the
Trentatron TAT-21 unit out performs the Neo Max Large Pipe
unit in every case here. And there is one big difference
here also, while the Neo Max Large Pipe unit magnets are as
thick as the Trentatron unit, they are half the width (1 Inch
wide vs. 2 Inches wide).
You need a magnet
here that is as wide as the pipe you are working with (or at
least close to it).
