Heat is a natural byproduct when operating an ultrasonic cleaner because ultrasonic energy is transformed into heat in an ordinary physical process. For instance, during permanent operation cleaning bath temperatures exceeding 60 °C (140⁰F) can be reached simply by the use of ultrasonic energy.
Temperature has a direct impact on the efficacy of the cleaning bath itself. As an example, in pure water cavitation is maximized at about 70⁰C (160⁰F) but this does not necessarily hold true when ultrasonic cleaning solutions are used in the tank. In such cases higher or lower temperatures are called for based on instructions provided by the cleaning solution manufacturer and the objects being cleaned.
