"A true addition for every grower

I use the USAF™ ultrasonic transmitters in our ponds and my dirty water drain. I notice considerable differences, the water is really much cleaner and more transparent because of these transmitters. As a result, the water pressure in the pipes is higher and our ponds are cleaner and stay clean, no more algae problems.

Especially with summer arriving, this is reassuring and you can water more often.

No adjustments are required to put these transmitters into operation, but the differences are quickly visible and obvious. The transmitters require no maintenance and therefore save a grower valuable time. The service from and communication with Ultramins is fast and good.

Furthermore, the guarantee, not good, money back, can be taken off, it just works

"After placing the USAF™ ultrasonic transmitters in our basins, silos and day stocks, we noticed significant differences. The first 2 weeks there was a little more pollution because the transmitters were cleaning up the algae and biofilm. Within 4 weeks, we could see that the water was much clearer and the biofilm and algae had disappeared. The water became much more transparent and cleaner everywhere, the measured values of our Vialux even doubled. Two dangerous fungi were found in the basins, which appeared to be no longer vital after plating at Eurofins.

So this system works very well and transmitters indeed do not need any maintenance or monitoring. As far as we are concerned, the USAF™ ultrasonic ToBRFV tests by Proeftuin Ron Peters also spoke volumes. Placement of the transmitters is child's play and no adjustments have to be made to the existing water system. The communication with Ultramins B.V. went smoothly and all agreements were met. We can really recommend this to every grower.

Ron Peters Trial - The first virus fighting company

"There is no doubt in my mind that this system from USAF™ works to eliminate ToBRFV and other micro-organisms in the drain and watering water. In addition, this system has major advantages over UV systems or a gas-based disinfector. This ultrasonic system does not require any maintenance and monitoring is also not necessary."

"Over a longer period of time, we did several tests and had leaf samples from these tests evaluated using PCR tests. The PCR results confirmed the image that the plants showed, as they were always happy. The plants that were given untreated virus water showed virus images within 2-8 weeks and became progressively weaker. It is important to mention that no grower will ever be able to get this virus ratio in his cultivation water, which makes the results obtained even more special."

Len Vander Lugt, CEO - Aldershot Greenhouses - Canada

"At AGL we placed Ultramins USAF™ ultrasonic transmitters in our silos with a diameter of 33 metres, we noticed after 14 days that the biofilm and algae started to disappear. After 4 weeks the water was clean and clear. The ultrasonic units work 24/7 and disinfect our water at low operating costs. Working with Ultramins was excellent. Robert is honest, knowledgeable and he delivered as agreed. USAF™ ultrasonic units work so well, we have just placed another order for more units for our silos at our other locations."

Alex Vellekoop - Duynplant - De Lier

We were on time with the installation of the USAF ultrasonic transmitters and even after very hot summer days we hardly have any algae in the pool. (3,000m2) The algae that are present are also all effectively killed. The service from Ultramins was excellent and reliable.


Frank Dekker - Dekker Glascultures - Prominent

"Clearly visible and fast a good result. After 21 years no more algae and biofilm and for many years no agrobacteria have been detected in our irrigation water. We do not use any other disinfection methods, so all these results are 1:1 due to the USAF™ ultrasonic transmitters. These transmitters require no maintenance or monitoring and work 24/7, 365 days a year, which is ideal because it saves a lot of time and the results are very good, monitoring by a renowned laboratory confirms this. The fact that very good results have been achieved with this solution in the fight against the ToBRFV virus puts me very at ease."

Our basin water has become much clearer and cleaner and no longer grows algae, which is truly unique. The biofilm present in our silos and the basin also disappeared quickly. The water from our mixing tank, 40% fresh water and 60% drain water, has even become crystal clear. Our filters remain much cleaner and there is no loss of water pressure at the back of our greenhouse, which saves me a lot of time every day, especially in summer. We are very satisfied and convinced of the effect of these transmitters. I can recommend every grower to install these USAF™ transmitters.


Ron de Bakker - Laguna Plants - Wateringen

"It was only when the transmitter was switched off that we saw that it was doing an excellent job.

We were sceptical when we bought the USAF basin transmitter. We only saw how well it worked after 3 weeks when we found out that we had cut the power cable while mowing the lawn and that the pool was green with algae. After we turned the unit back on, it quickly recovered. The transmitter keeps the pool clear, clean and free of algae. The biofilm in our pool is now very tidy."


Simon Zwarts - Zwarts Gerberas - Mijdrecht

"In the 8 years that we have been using these transmitters, we have had clear, clean basin water and never any clogged filters.

The pool is free from biofilm and the water is always clear and clean. We are very satisfied with the performance of the ultrasonic transmitters in our basin. (ca. 2,400m2)".
