Rama R2F 28kHz/40kHz Smart Ultrasonic Cleaner

In the field of industrial cleaning, not all stains are the same and not all materials can withstand the same impact force. Understanding that, the Rama R2F ultrasonic cleaning tank line was born, providing a breakthrough solution with the core feature of the ability to customize the operating frequency , allowing users to have complete control over the cleaning process.

Flexible customization between 28 kHz and 40 kHz

No longer limited to a single frequency, Rama R2F empowers you to choose the cleaning power that best suits each specific task. This is a game-changer.

Switch to 28 kHz mode: Activates coarse cleaning power

• When you turn on the 28 kHz frequency, you are activating a powerful, deep cleaning mode. Ultrasonic waves at this frequency create large cavitation bubbles that release maximum energy as they collapse.
• Practical application: This is the ideal choice to handle the “heaviest” challenges :
  • Removes hardened industrial grease.
  • Breaks down carbon deposits and surface rust on machine parts.
  • Remove mud, dirt and coarse impurities from metal blocks and molds.
  • Simply put, 28 kHz is the “attack mode” for tackling stains that conventional methods cannot clean.

Switch to 40 kHz mode: Enables fine cleaning precision

• Switching to 40 kHz, the device creates a “storm” of microscopic, densely packed air bubbles. These bubbles are gentle yet effective, penetrating every tiny nook and cranny.
• Practical application: This is the perfect choice for jobs that require finesse and high precision:
  • Perfectly cleans electronic boards without damaging components.
  • Deep cleaning of medical and dental instruments with complex structures and many grooves.
  • Clean off any polishing compound left in the small crevices of the jewelry.
  • This is the “expert mode” to ensure the item is not only clean on the surface but clean down to the microscopic details.

Optimal cleaning process with 2 Frequencies

Owning the Rama R2F means you can set up a professional two-stage cleaning process in a single device:

1. Stage 1 (Coarse cleaning – 28 kHz): Starts with low frequency to quickly remove 90% of stubborn stains.
2. Stage 2 (Fine cleaning – 40 kHz): Switch to high frequency to complete the process, ensuring complete removal of microscopic dirt, returning a perfectly clean surface.

Diverse capacity, expanding application capabilities

The R2F series inherits the size diversity of the RT series, but with enhanced efficiency thanks to dual-frequency technology.

• Wide range of capacities: Provides many options from 3.2L, 4.5L, 6.5L to 30L , meeting the needs of individuals, clinics, and industrial factories.
• Optimized for all sizes:
  • Small models: More versatile, can clean jewelry and eyeglasses (at 40kHz), and can also clean small, heavily soiled mechanical parts (at 28kHz).
  • Large models: Maximize power, allowing rough cleaning of large machine blocks and molds (at 28kHz) and then fine cleaning of smaller batches of components (at 40kHz) in the same unit.

Scope of practical application

The combination of two frequencies makes the Rama R2F suitable for workshops, laboratories or production facilities that need to handle a wide variety of objects.

• In the mechanical and automotive industry: 28 kHz frequency can be used to pre-clean machine parts, engine blocks, carburetors covered with grease and thick dirt. Then, switch to 40 kHz frequency to clean fine parts with small details such as injectors, valves, or bearings.
• In the medical and dental industry: 28 kHz frequency can be used to remove hard plaque such as dental cement, dried blood on instruments. 40 kHz frequency is suitable for deep cleaning and disinfection of instruments with complex structures and many grooves.
• In the electronics industry: 40 kHz is the standard choice for cleaning electronic circuit boards (PCBs) of solder paste and dirt without damaging the components. 28 kHz can be used for larger mechanical parts of the device.
• In the jewelry industry: The process can start at 28 kHz to remove polishing compounds left over from the manufacturing process, and end at 40 kHz to clean and polish the finished product, especially items with gemstones.

The Rama R2F is more than just an ultrasonic cleaner. With its flexible frequency adjustment, it is a customizable cleaning system , giving you the power and precision needed to tackle any cleaning challenge, from the roughest dirt to the most delicate details.
