About us

From Zwaag, we supply ultrasonic transmitters that optimise water. Our transmitters disinfect, prevent fouling and combat micro-organisms. The use of our ultrasonic transmitters is environmentally friendly, easy to install and usually completely maintenance free. Every company is unique, we always make an inventory of the situation together with you and based on that we make a recommendation. If necessary, we come and see what the best solution is. We always want to make sure that the right results are achieved in the fight against micro-organisms. An additional advantage is that the use of ultrasonic can reduce the use of expensive pesticides or fuel. (The payback time is usually under 18 months)

We are convinced that with these applications, the environment wins, our customers win and we win...and that there are only winners, that's really ultrasonic!

After the owner Robert de Hoo gained many years of experience in various industries in distribution, production and sales & marketing, he came in contact with Kees Luijkx. Kees is the owner of Luijkx Ultrasound B.V. and the manufacturer of USAF™ ultrasound products, with 25 years of experience in ultrasound technology. Robert became very enthusiastic about all the stories, reports and studies about the use of ultrasound. The increasingly strict environmental requirements will also help the growth of this technique. So Robert also saw plenty of commercial opportunities and Kees was looking for a company that could continue and further expand sales. A new company called Ultramins was quickly established.

A unique name composed of 3 words 'ultrasonic', 'vitamins' and 'less'. Ultrasonic speaks for itself, the technique on which everything is based. Vitamins' because we treat water that becomes 'better' after treatment with ultrasonic, so you can see ultrasonic as a vitamin. Less' because there are fewer micro-organisms in the water after treatment and therefore fewer pesticides are needed. And less because we make sure there is less fouling and less fuel is needed in shipping. Less pesticide and less fuel means less impact on the environment, and that, of course, is becoming increasingly important!
