  • Potential Acceleration of Unwanted Chemical Reactions: Heat can speed up chemical reactions. This can lead to the creation of potentially harmful gases, especially when certain cleaning solutions are used.
  • Reduced Equipment Life Expectancy: Excessive heat may lead to accelerated wear and tear of the components of ultrasonic cleaning equipment.
Always use appropriate safety measures and follow the manufacturer’s guidelines when using heat with ultrasonic cleaning.

Key Features to Look for in a Heated Ultrasonic Cleaner

The key features of a heated ultrasonic cleaner should have vs. a non-heated one are:
  • Heating Function: While obvious a need, be careful to look for this specifically when choosing your system.
  • Adjustable Temperature Control: This allows you to set the heat level as needed for different types of items and levels of dirtiness.
  • Timed Heat Settings: These allow you to control how long the solution stays heated during the cleaning cycle.
  • Automatic Shut-off: This prevents accidents that can occur when the temperature gets too high for any reason.
All other features related to the operation, such as frequency range, capacity, construction material, timer, ease of use, safety features, drainage system, noise level, and warranty, are generally the same for both heated and non-heated ultrasonic cleaners.

How Do I Determine the Correct Heat Settings for My Ultrasonic Cleaning Tasks?

For industrial ultrasonic parts cleaning, the correct heat settings will vary based on the type of contaminant and the material of the parts.
Here are some general guidelines:
  • Light oils, dust, or fingerprints: These can often be removed at lower temperatures, around 50-60°C (122-140°F).
  • Cutting oils, heavy grease, or similar contaminants: Higher temperatures, around 70-80°C (158-176°F), might be necessary.
  • Very stubborn residues or contaminants: Occasionally, temperatures up to 90°C (194°F) may be needed.
However, these are just general guidelines; you should not see them as recommendations. Always refer to the manufacturer’s instructions or material safety data sheets to ensure the chosen temperature won’t damage the parts.
