Cooling Tower

Refrigeration systems are an important tool for production in the food industry and other sectors of the economy. The operation of the plants is subject to strict terms and regulations. The functionality of most refrigeration systems is water-based. Effective biocides are used to prevent growth in biofilm and associated growth. Non-cavitative ultrasound is environmentally friendly, climate neutral, leaves no residues and works very effectively. The use of substances according to (EU) No 528/2012 will be greatly reduced and in most cases no longer necessary. With just a few transducers, your systems can be equipped very quickly. The installation is easy for your facility management after a short briefing.



The technology is based on the application of ultrasonic vibrations and signals in the range 20 - 80 kHz, which are mounted on the drive and tank systems by means of so-called transducers. This technique uses not only the pure ultrasound reflected from the water back to the system, but also a software-based frequency of the signals. As a result, the sound signals vary in radiation strength, frequency and amplitude and generate by vibrations an adhesion (organic and inorganic deposits = conditioning film) and colonization hostile (slime-forming microorganisms) milieu. The deposits of organic material and the first colonization by microorganisms, commonly referred to as "biofilm", are prevented. At the same time, bacteria and algae are killed by destroying their cell organelles/vacuoses, as well as larvae and single-celled organisms up to 10 days old. Thus, the adhesion and development of algae, mussel or smallpox growth is permanently disturbed and prevented. The principle of action is purely physical in nature. It does not alter water structures or affect water molecules, the low-intensity radiation energy (6 to 35 watts) has no influence on material or compounds, welds, etc. A positive side effect is the removal of residues and deposits such as rust or boiler stone and the prevention of corrosion over the application period. The patented HARSONIC ® transducer technology contributes substantially to environmental protection, as the use of chemical agents is drastically reduced and thus sufficient protection is achieved in salt and fresh water. Due to the low radiation power of max. 35 watts per transducer, however, a surface to be treated cannotbe quickly cleaned of existing vegetation by the HARSONIC® technique. Prerequisite for the use of our technology is the absolutely thorough cleaning of the inside of the pipe or other surfaces (such as the hull of ships, tank systems, etc.) before installation and commissioning, the correct positioning and sufficient number of transducers used and a permanent power supply. A schematic representation (if material has been provided by you) of an installation can be found below. In this system, the fuselage or surfaces are sonicated with a transducer (sound transmitter). The sound is emitted via the surfaces, pipes and collection containers, is reflected by the water and then acts on the complete surfaces in the area of the system. This ensures the sonication of the entire system. Details are listed in the installation guide.
