Nowadays a wide range of ultrasonic washing devices or so-called "hand size machines" appeared in the market. On can mention "Retona", "Pony", "Ultratone", "Pchelka", "Solana", Volkano", "Bionika", "Volshebniza" and others. Last time their assortment increased greatly.
By the sight of an ordinary consumer all the available models look the same. All of them consist of a power unit and a radiator connected by a flexible cable. Their principle of operation is based on conversion of electrical energy into acoustical one (ultrasonic waves) by a piezoceramic element. The idea of using ultrasonic waves for washing is not a new one. It has been used in industry for a long time. For instance, ultrasonic bathes for cleaning various parts in water medium are produced in series. One may ask the question "What is the difference between all these washing devices?"
The difference is in radiator design and principle of its operation. Therefore there is a difference in consumer characteristics of ultrasonic washing devices, for instance in washing off degree.
The main goal of each acoustical generator designer is to produce maximum acoustical energy, which determines essential consumer characteristics of the washing device, with a minimum electrical energy consumption.
In the opinion of experts, one compulsory condition of the efficient ultrasonic effect is the presence of a developed cavitation zone near the radiator. It can be achieved when acoustic power radiation exceeds 1-2 W/cm2. The evidence of the cavitation mechanism, which effects a washed fabric and a detergent solution are important liquid velocities caused by the movement of cavitation bubbles. These bubbles can separate soiled particles from fabric fibre. In addition, the high-pressure regions created by the explosion of air bubble effectively grind the soiled particles facilitating their transfer to the detergent solution.
Why we do recommend «Colibry»
Comparative washing off degree tests for the devices available in consumer market have shown that this goal is achieved by "Colibry" in the best possible way for the following reasons:
- The highest value of the radiated acoustical power : 0.6 - 1.0 W/cm2
- The cylinder shape of a radiator makes it possible to ensure 3D propagation of ultrasonic waves though the whole volume of the washing capacity.
- Pulse mode of operation ensures the increased washing off efficiency without damaging clothes.
- Economical operation: "Colibry power consumption is 15 times as less that of the most efficient machines of activator type (you may agree that it is very important today).
- Gentle washing: clothes do not undergo mechanical treatment and serve longer This is especially important for fine clothes like wool, silk, chiffon, cambric etc.
- Portable design. Consumers are surprised and happy with "Colibry" weight of only 350 g.
- Disinfection: "Colibry" eliminates colinbacillus and staphylococcusaureus microflora,
which is the cause of manyillnesses (dysentery, colienteritis, meninditis, pneumonia, purulent diseases of wounds and skin, renal, auricular, nasal diseases etc.) That is confirmed by Research Institute of Hygiene (medical certificate №16/308 of December 20 1996).
- Prolonged Guarantee: guarantee term is 2 years!
- Reasonable prize ( about $ 50 )
