FAQ

Can flammable liquids be used undiluted in the ultrasonic bath?

In no case, the use of chlorinated and fluorocarbons is also prohibited for work and environmental reasons.

Is the ultrasound perceptible to human hearing?

The ultrasound is not audible. Nevertheless, the device generates cavitation, which creates a hissing sound due to implosions. This sound is heard from the human ear.

The frequency between 20-40kHz is therefore not audible.

Can normal tap water be used in an ultrasonic bath?

This is even recommended. Tap water offers excellent properties for cleaning in an ultrasonic bath, since the mineral substances also increase the ultrasound.

If the water is too hard (this information is available from your water supplier), a degassing process should be carried out before cleaning.

Why cleaning concentrates?

In addition to deep cleaning, the ultrasound also reduces the time, which, with the addition of a suitable cleaning concentrate, reduces the cleaning time by up to 80% to just a few minutes. The efficiency of the cleaning effect can be increased by heating the bath temperature. Some cleaning concentrates only achieve their full effect with heatable ultrasound devices. Cleaning concentrates are biodegradable, they loosen and bind the dirt particles.

What to do if cleaning concentrates are swallowed?

What can be cleaned with ultrasound?

Basically all solid materials. In the jewelry area, soft stones e.g. Opals, corals etc. cannot be cleaned in an ultrasonic bath.

How does ultrasonic cleaning work?

If ultrasound is introduced into liquids, microscopic vacuum bubbles are created which immediately implode again. This process is known as cavitation. The individual cavitation bubbles then blow the dirt off the hard surface of the items to be cleaned. However, the surface is not damaged. The result of ultrasonic cleaning is clean parts down to the pores.

Which ultrasound machine is right for me?

The inner basket size should always be the yardstick. Since all EMAG ultrasonic baths are made of stainless steel, but they are not immune to scratches or damage, it is advisable to always use a cleaning basket (usually included). Your product should have sufficient performance for your application. Rule of thumb: The larger a device, the greater the power it can generate. The larger a product, the more power is required to produce a sufficient cleaning result. The more contaminated a product is, the more power is required to clean it. Once you've decided on a size, it's all about the series. Here is an overview of all EMAG series:

Emmi HC series: Impresses with its robustness thanks to the stainless steel housing. Equipped with timer, heating power regulation and ultrasound regulation.

Emmi H series: This series is characterized by high robustness and new ultrasound technology. Equipped with timer and heating output regulation.

Emmi D series: Very high performance, robustness thanks to stainless steel and ultrasound of the latest generation are the hallmarks of the new D series. Equipped with time switch, heating power regulation, ultrasound regulation, degas function and sweep technology.

Do I need a heater:

Not for smaller plastic or material parts or for disinfection. Products made of multi-composite parts as well as metallic parts with strong impurities are usually cleaned much better by heat. The best cleaning result is achieved with the right heat setting, the right water / detergent mixture and the right cleaning time.

How long does the ultrasound device take to heat up:

Ultrasound devices are not kettles and are not designed to reach high temperatures immediately. Therefore, the devices need a certain amount of time to reach the right temperature.

The following information requires the use of ultrasound during the heating phase (water at room temperature):

0.8-6.0 L

30 ° = 10-15 min., 50 ° = 30-40 min., 70 ° = 60-90 min.

8.5-13 L

30 ° = 10-20 min., 50 ° = 45-60 min., 70 ° = 80-90 min.

28-80 L.

30 ° = 15-25 min. 50 ° = 45-60 min., 70 ° = 80-90 min.

What is the right concentrate, the right time and the right heat setting for me?

Unfortunately, this point cannot be answered sufficiently for everyone. Rather, cleaning with an ultrasonic bath is like a series of tests in a laboratory. What is the solution for one presents new problems for the other.

Nevertheless, we hereby provide you with a short guide for the most common cleaning cases:

Glasses: EM-080, max. 3%, 1-2 min. depending on the pollution and device, without heating. The cleaning can easily be done several times a day without causing damage.

Prostheses and hearing aids: EM-070, max. 2-4%, 5-15 min. depending on the pollution and device, without heating

Jewelry and coins (cleaning): EM-080, EM-300, max. 5%, 5-15 min. depending on the contamination and device, up to 50 degrees

Boards: EM-303, 1-4%, 10-15 min. depending on the pollution and device, 30-40 degrees

Stainless steel and aluminum (carburetor, weapon parts, engine parts, industrial plates made of metal): EM-080, EM-300, EM-404, 3-7%, 10-40 min. depending on the contamination and device, up to max. 65 degrees
