Degreasing and particle decontamination of complex parts by flood cleaning with ultrasound and Cyclic Nucleation process

3 standard sizes

The PowerJet cleaning machine is available in 3 standard overall dimensions depending on the size of the parts to be processed and the volume of parts to be processed.

For special applications, the working chamber can be custom-made.

  • PowerJet 530 > 530 x 320 x 200 mm

  • PowerJet 670 > 670 x 480 x 300 mm

  • PowerJet 960 > 1020 x 650 x 560 mm

Work chamber of flood cleaning machine with ultrasound and CNp

A modular system

The PowerJet allows the use of the well-known cleaning and drying processes according to the expected cleanliness requirements.

Its flexibility allows the treatment of highly contaminated parts as well as the disinfection of medical devices (MD).

  • Spraying – Simple or special flood cleaning – Ultrasound – Cyclic nucleation (CNp)

  • Hot air drying – Vacuum drying

PowerJet Twin / Triple

When applications require a separation of each cleaning steps or when the production rate requires saving processing and loading time, the PowerJet is a standard machine in a multi-chamber version.

  • PowerJet Twin > 2 chambers

  • PowerJet Triple > 3 chambers

Multi-chamber version of flood cleaning machine

Fluid treatment

Operating in a closed circuit, excellent fluid treatment is essential to achieve repeatable cleanliness results and drains the bath regularly.

  • Oil skimmer

  • Distillation for aqueous solution treatment

  • By-pass filtration for continuous bath treatment

High purity parts cleaning machine


The loading and unloading of the PowerJet system is fully automated with an automatic conveyor integrated with the machine.

In the case of multi-chamber machine especially in final washing in a high pace environment, it allows the loading and unloading of parallel chambers simultaneously.

Principle of flood washing

Flood cleaning consists of constant pressure changes in combination with the basket rotation.

The working chamber evolves from overpressure to depression, producing reverse flow variations to clean cavities and deep drilling.

PowerJet flood washing is particularly effective on surface contamination and chips.

Industrial parts flood cleaning

Using ultrasound

Ultrasound diffuses into the fluid and generates cavitation and micro-currents that allow to clean parts. The lower is the frequency, the more intense is the action.

Depending on the fragility of the material and the adhesion of the contamination, the frequencies to be used are different:

  • 25 to 40 kHz > general industry and automotive

  • 40 to 120 kHz > jewellery, optics, medical, electronics

  • 250 kHz to 1 MHz > semiconductors, precision components, nanotechnology, photovoltaics etc…

High purity cleaning machine applications

Cyclic Nucleation process (CNp)

CNp technology ensures an ultra-efficient cleaning of complex geometries such as grooves, blind holes and narrow channels without attacking the surface of the parts. As part of the PowerJet, the CNp opens up new cleaning opportunities in many areas:

  • Cleaning capillary components

  • Depowdering after additive manufacturing

  • Disinfection of medical instruments (MD)

High purity

For highly sensitive cleaning applications, PowerJet’s design is upgraded to be a transition between the grey room and the cleanroom.

  • Semiconductor
  • Medical devices
  • Optical components (lasers and sensors)
  • Components with microstructures
