NDV Ultrasonic placed on the hot water pipe in an apartment in Spain.

We had a lot of lime deposits since the apartment is uninhabited for more than 10 months and the water remains in the pipes and boiler. Is now resolved, thanks NDV Ultrasonic Dirk & Ann C.

My neighbor had told me that they had a solution to our problem of lime and bacteria.

We also had an NDV Ultrasonic installed, and we clearly notice the difference.

Thank you Nick for the good service, S.O

As you’ll see, I made a copper bracket and dyna-bolted it to pool wall.

You’ll note in the video there is a slight bit of ‘green’ on some of the floor/walls.

This now seems to have gone.

In coming days I’ll send you some more photos/video of a ‘cleaner’ looking pool.

So, it all appears to be working fine.  Blue light flashes and an audible clicking sound in the water.  And the temporary off button works fine.

Thanks Nick,

Kind regards

Troy

I have a 100,000 litters clear water pool located deep in the tropics of Costa Rica. I use the NDV ultrasonic device as part of this unique eco pool design. We use no Chlorine nor salt, the pool water stay clear using no chemicals year round even during the heavy rains season. The NDV device is easy to install, has no maintenance and operates seamlessly. Customer service is impeccable as well as tech support. I am pleased with the performance and even ordered a second unit. R.K

Year after year the boat came out of the water, sanding and scratching to remove the algae and smallpox.

Having been introduced to Nick de Vos of NDV Ultrasonic, I am very happy that my boat is now completely free from smallpox and algae from the water. For me, the NDV Ultrasonic installation has been fully reimbursed after 4 years and with much less work. I'm curious how long I can keep my antifouling now, it has been on it for 2 years and we go to the third year! Nice to have this installation and I recommend it every boat owner! J.S.

No more blockages and no intestines that jump due to too high pressure due to narrowing of the intestines.

Thank you Nick NDV Ultrasonic. Horemans.
