Ultrasonic coin cleaner

Types of ultrasonic coin cleaners

An ultrasonic coin cleaner is a machine that uses ultrasonic waves and a cleaning solution to clean coins. The technology was invented in the 1930s but became popular in the 1950s because of its effectiveness. Ultrasonic cleaners work by creating millions of tiny bubbles in a liquid cleaning solution. As the bubbles form and collapse, they gently remove dirt, dust, and other debris from the surface of the object.

Ultrasonic cleaners are suitable for cleaning different items like coins, jewelry, medical instruments, and industrial parts. However, ultrasonic cleaners for coins come in different types depending on the type of coins being cleaned.

• Desktop Models:

  Desktop models are the most common type found in homes and offices. They have a small tank capacity of about 1-2 liters. Desktop models are ideal for hobbyists or anyone who handles a few coins. Even though they are not meant for heavy use, desktop models clean coins effectively using ultrasonic technology.

• Industrial Models:

  Industrial models have a larger tank capacity of more than 20 liters. They are mainly used in industries that handle large quantities of coins. Because they have powerful transducers, industrial models can clean coins faster than other models.

• Heated Cleaners:

  Heated cleaners have a heating mechanism that increases the temperature of the cleaning solution. The increased temperature improves the cleaning process and shortens the cleaning time. Heated cleaners are suitable for removing stubborn dirt from coins.

• Portable Cleaners:

  Portable cleaners are small-sized ultrasonic cleaners. They are battery-powered, so they can be used anywhere. Collectors who work on field projects prefer using portable cleaners because they are lightweight and easy to carry around.

• Multi-Purpose Cleaners:

  Some ultrasonic cleaners have additional attachments for multi cleaning purposes. The attachments can be brushes or different cleaning solution tanks. Also known as Swiss Army ultrasonic cleaners, they can be used to clean multiple items, such as coins, jewelry, eyeglasses, and watches.

Function and features

• High Frequency Cleaning Action:

  Ultrasonic cleaners use a high-frequency sonic wave (usually between 20kHz - 40kHz) that passes through the cleaning solution and agitates it. The agitation creates millions of microscopic vacuum bubbles, which collapse and release intense cleaning energy. This process removes dirt and grime from even the most inaccessible places.

• Heated Cleaning Solution:

  The ultrasonic cleaning action is more effective when combined with a heated cleaning solution. The heat helps to lower the surface tension of the liquid, which enhances the cleaning action further.

• Effective & Efficient Cleaning:

  The ultrasonic cleaning action offers a consistent and uniform cleaning process. Unlike manual cleaning, ultrasonic cleaning can reach all surfaces and crevices of an object. Compared to manual cleaning, ultrasonic coin cleaning is faster and more efficient. It reduces cleaning time while improving cleaning standards. This makes it perfect for coins, jewellery, or any other intricate parts. The coins will come out looking shiny and new.

• Easy To Use & Control:

  Ultrasonic cleaners are easy to use. Just place the item to be cleaned inside the tank, add the right cleaning solution, and set the cleaning time. Most machines have a digital timer for precise timing. Operators must follow the manufacturer's instructions for optimal results. The user-friendly controls make ultrasonic cleaners accessible to both experienced users and beginners.

• Wide Applications:

  Ultrasonic cleaners have many applications across different industries. They are used to clean delicate and intricate parts in sectors like aerospace, automotive, engineering, healthcare, jewellery, and many others. The machine's versatility makes it an effective solution for any business. Having different cleaning solutions for various applications enhances the cleaner's performance further.

• Optics and Eyewear Cleaning:

  Optical devices benefit from ultrasonic cleaning to keep their lenses and other parts in top condition. The cleaning eliminates any residues that may impair vision or optical performance.

• Ultrasonic Dental Cleaning:

  Ultrasonic cleaners assist dental hygienists in cleaning instruments and tools. The gentle and effective cleaning ensures each instrument is properly maintained for the dental setup.

How to choose ultrasonic coin cleaner

• Think about the type of things to clean:

  Knowing what needs cleaning helps pick the right cleaner. Some places have lots of jewelry or old coins, while others sell machine parts. Jewelry stores should get cleaners made for small, detailed items. Stores with coins should buy ones that work well with metal mixes. Places that clean tools need machines that can handle tough dirt.

• Consider the size of the ultrasonic cleaner:

  Always choose an ultrasonic coin cleaner based on the amount of coins to be cleaned at a time. A small unit is ideal for cleaning just a few coins, while a large one can handle hundreds of coins in a single batch. Remember that larger models give more room inside their tanks.

• Look at the quality of the ultrasonic cleaner's parts:

  The cleaner's build shows how long it will last and how well it will work. Go for cleaners with durable tanks and good lids that won't break or warp from using hot or harsh cleaning liquids. Check reviews to see if other people have found any problems or effective cleaning results.

• Be aware of the frequency range:

  Ultrasonic cleaners typically operate between 28kHz and 40kHz. Lower frequencies in the 28 kHz to 36 kHz range are better at removing heavy dirt, while higher frequencies provide a gentler cleaning action that prevents damage. A frequency cleaner with a dual frequency provides the safest, most effective cleaning. It gives a more gentle cleaning of the delicate parts and a more aggressive cleaning for the Coarse parts.

• Consider the size of the ultrasonic cleaner's tank:

  Tank sizes may range from only a few ounces to several gallons. It's best to estimate how much dirt can be cleaned in a single batch. A larger tank is ideal for cleaning a ‌greater number of coins; otherwise, multiple batch cleanings may be needed.

• Check if it has a heater and a filter system:

  Having a filter makes the cleaner more efficient, while the heater helps the cleaner work faster. Filters keep the cleaning liquid fresh by catching dirt particles.

• Know how much it costs to operate:

  Beyond the initial purchase cost, coin cleaner costs matter too. Consider what it takes to keep the machine working each month. Some machines use less electricity and cleaning fluids, which is helpful. Be sure to check if operating these machines requires any special cleaning solutions, as additional costs for many may become unprofitable.
