LET’S GET TO KNOW EACH OTHER

Founded in Senigallia in 2004, RadioAstroLab is an electronic design company focused mainly on the production of professionalultrasonic cleaning and washing systems for industry and laboratories.

The effectiveness of ultrasonic cleaning and washing systems in efficiently and non-invasively removing contaminants from complex surfaces, in areas that are difficult to reach with traditional methods, is well known. Using high-frequency sound waves (generally between 20 and 80 kHz) propagating within a cleaning liquid (or simply water), the system generates a phenomenon known as cavitation (the formation and collapse of microbubbles), a mechanically energetic process that breaks up and removes dirt particles, oils, greases, metal residues, oxides, and other impurities.

Sophisticated electronic generators power arrays of piezoelectric transducers, which, vibrating at ultrasonic frequencies, generate the mechanical energy needed to trigger cavitation in the liquid. The power, operating frequency, and other parameters that govern the system’s operation depend on the size of the washing tanks, the treatment requirements, and the nature of the surfaces being cleaned. This is a proven technology, suitable for a wide range of applications where it is important to remove the most stubborn dirt residues without damaging the treated surfaces, minimizing the use of aggressive solvents, and ultimately optimizing operational efficiency, time savings, and energy consumption.

Our range of ultrasonic cleaning products includes:

• System with submersible radiant plates and independent US generators, where the radiant plates are separate modules containing multiple piezoelectric transducers electrically connected in parallel, hermetically enclosed within a rectangular AISI 316 stainless steel box. Each plate is connected to an external ultrasonic generator and is immersed in pre-existing tanks. Equipped with suitable mechanical supports (almost always custom-made), a radiant plate can be positioned on the bottom, on the side walls, or suspended inside the tank.

• T-25 ultrasonic tank: built as a monoblock unit comprising piezoelectric transducers (components that radiate ultrasonic energy into the cleaning liquid, usually glued to the bottom or side of the tank) and the ultrasonic generator (US) that powers the transducers. The transducers are fixed, and the system is designed to provide a relatively economical “turnkey” solution, suitable for small to medium-sized plants. Our T-25 model is an excellent example of a machine suitable for a wide range of ultrasonic cleaning applications in laboratories and small-scale industries. This model has a capacity of 25-28 liters, but tanks of other sizes/capacities can be designed and produced upon request. Combined with our range of detergents, it allows for perfect cleaning of immersed parts, removing any residual dirt. An optimal combination of ultrasonic generator parameters (power, frequency, and modulations), treatment time, and temperature offer results otherwise impossible with traditional cleaning systems.

The traditional monoblock ultrasonic cleaning tank is ideal for use in laboratories or small industrial production facilities, where a system with submersible radiant plates may be too expensive or oversized. This solution, with a lower initial cost and less flexibility, benefits from simple and immediate installation (plug & play). In industrial production, where powerful modular systems characterized by high flexibility and customization are required, or where existing tanks (not necessarily made of metal) need to be retrofitted, it is practically mandatory to choose a cleaning system composed of several modular units, each composed of a radiant plate with its own US generator. The number of modules used will be determined by the tank capacity. These systems, while having a higher initial cost, greatly simplify integration with existing production lines and allow for easy maintenance.

• Our robust and sophisticated ultrasonic generators are equipped with dedicated microprocessors for managing operating functions and programming parameters. A control system continuously monitors the operating conditions of the generator and washing tank, blocking the machine (with an audible and display alarm) if any anomalies occur. Regardless of the operating conditions, the maximum power output of the ultrasonic generator is automatically limited to a value established by the manufacturer. Upon request, we can supply transducers; otherwise, we customize those sent by the customer to ensure optimal board-transducer matching.
