Ultrasonic Cleaning
In ultrasonic cleaning, contaminants are removed not with solvents, but with the help of ultrasound. Tap water is used to transmit the energy, to which a surfactant is added to reduce the surface tension of the water (and improve the efficiency of the cleaning).
Ultrasonic cleaning is primarily used for cleaning jewelry, precision mechanical parts (e.g., mechanical watches), dental or surgical instruments, and optical lenses. The advantages of ultrasonic cleaning include its ability to remove almost any type of contamination from the surface of the item being treated, without structurally damaging the item.
Ultrasonic cleaning uses high-frequency (typical frequency: 20–400 kHz) sound waves to mechanically remove contaminants from hard surfaces in aqueous or organic solutions. The ultrasound causes cavitation in the liquid, during which tiny bubbles are formed (the size of these bubbles is roughly inversely proportional to the applied frequency), which mechanically loosen the contaminants, settling at the bottom of the container used in the process. The tiny bubbles also exert their effect in hidden, hard-to-reach parts of the item.
A substance is added to the water depending on the type of contamination, which reduces the surface tension of the water, thus making the formation of air bubbles more significant. The temperature of the water (around 40-60°C), the frequency, and the duration of the cleaning (a few minutes or even several hours) are set empirically. The required power demand is typically 10 watts per liter.
The typical components of contamination are dust, grease, oil, and organic matter. It is not necessary to disassemble the item to be cleaned. The process does not cause mechanical changes in the item being cleaned.
To generate ultrasound, a piezoelectric or magnetostrictive vibration generator is used, which either immerses in the liquid or is rigidly fitted to the wall of the container holding the liquid.
This technology is very well suited for the external and internal cleaning of boiler bodies.

System Flushing
System flushing is now almost essential before replacing a boiler. New condensing boilers are more sensitive devices than their predecessors, and efficient, trouble-free, and long-lasting operation requires a heating system with clean and adequate water quality. However, old systems also benefit from an update!
The longer lifespan and trouble-free operation necessitate the removal of contaminants at high flow rates using chemicals. Without this, operational issues such as knocking, performance reduction, and leaks may arise within weeks or months. The most effective tool for flushing heating systems is cleaning with a machine system. Various descaling and rust-removing chemicals must be used in every cleaning case. Purely machine cleaning with clean water is insufficient. It is possible to clean only the heat exchangers, but it is more advisable to treat the entire system comprehensively. With agents that have a nearly neutral pH, and by utilizing the advantages provided by the cleaning machine, contaminants can be loosened and flushed out of the system.
Old cast iron systems, with outdated radiator valves, possibly taps, may show signs of rust in places. Such and similar systems must be handled with care. In this case, washing with additives is not advisable, as it can easily dissolve contaminants where leaks may occur.
The purpose of flushing the heating system:
1.) The goal of reconstructing the heating system is to achieve heating performance close to the original state.
2.) Protecting the flushed heating system from the formation of corrosion and other chemical processes.
3.) Maintaining the normal state created in the heating system in the long term.
4.) Much more even heat distribution within the property.
Cost of heating system flushing service:
15,000 HUF net (per radiator or per underfloor heating circuit.)
1 chemical set (solvent and inhibitor) is needed for about 10 radiators (or p. circuits)
The price of the chemical set: 45,000 HUF gross
