Family Fresh Farms - Patrick de Craen - Baby Cucumbers - Australia 

UPDATE 2026:

“After installing the transmitters, we noticed that our UV installation performed much better. The T10-value increased from 22 to even 45 during the winter months and to 35 in the summer. Without the transmitters, these values would have been unattainable. For us, this is proof that this technology also has a positive effect on other equipment, making the investment even more economically attractive. We had already seen earlier that nanobubble generators were working better.”

"Shortly after installation, we already saw a positive effect on water quality; pathogen pressure decreased."

For several months, we have been using USAF™ transmitters from Ultramins in our entire water chain, from basin to day supply.

I am the (Dutch) site manager at Family Fresh Farms in Australia, where we grow Qukes™ Baby Cucumbers in two high-tech greenhouses of 2.5 hectares each.

I was already familiar with the transmitters through a contact in the Netherlands who had very good experiences with them in cucumber cultivation. This piqued my interest and I was curious whether the transmitters would also be effective under the extreme climate conditions here in Australia. Our aim was to control algae and biofilm and reduce viral pressure from the water. At the time of installation, we were already using UV filters and nanobubble generators, among other things. Shortly after installation, we already saw a positive effect on water quality; pathogen pressure decreased.

What extra surprised me, however, was the excellent cooperation with the nanobubbles! It was only after adding the USAF™ emitters that oxygen levels in the water began to rise significantly, which was clearly visible in improved root development. Even at extreme temperatures and high sunlight, the transmitters worked extremely well for controlling algae in the basin water. In addition, we found that no waterborne virus was present in the drain water. What else stands out is that our misting/misting system no longer clogs up, which saves us a lot of time and therefore costs.

In short, we are very satisfied with this investment; the transmitters have made our water quality significantly improved and certainly contribute to increasing production per square metre. Also about Ultramins we are positive their support and service are of a high standard and they guided us excellently.
