ULTRASONIC FAQ'S
| |
Q.
Q. |
How does the ultrasonic cleaning process work?
Why should I consider using ultrasonics? |
A.
A. |
Ultrasonic cleaning works by introducing energy into a tank containing the cleaning solution. This energy causes minute bubbles to form and collapse within the solution, this action being called cavitation. The cavitation leads to a very gentle but highly effective scrubbing action on the component surface that loosens the contaminant.
Ultrasonics offers a rapid and highly effective method of precision cleaning components to a very high standard. Manual cleaning or spray wash methods may struggle with blind holes, tube internals or difficult to reach crevices but these problems are easily dealt with when ultrasonics are used. |

Dependent upon the application, better cleaning standards can also offer further benefits of improved quality and reduced costs.

Q.
|
How do I choose between ultrasonics and spray wash?
|
A.
|
Aqueous spray washers are excellent for a wide variety of cleaning applications. Both stand-alone basket washers and conveyorised multi-stage equipment (incorporating rinse and dry sections if required) can often
achieve rapid throughput plus high standards of cleanliness. In certain
cases, heavy soils are better dealt with by spray washing, due to the impact of the pumped cleaning solution through the wash jets.
In other instances, spray washing and ultrasonic cleaning may both achieve the required cleanliness standard and throughput requirements, so the choice may be one of cost or preference.
However, there are applications where ultrasonic cleaning offers a clear advantage over spray washing. Examples include the following:
- Components with deep, blind holes or complex geometries
- Tubular components
- Delicate or lightweight components that could be susceptible to damage
- Achieving sub micron cleanliness standards or cleanliness levels measured in parts per billion (ppb)
To help you find out which process may be most suited to your application, we offer a free of charge evaluation service. Our demonstration facilities at Skipton and Hitchin have a wide selection
of both spray wash and ultrasonic cleaning machines and we can
perform cleaning trials on your own components to establish the
optimum process.

Q.
|
I have an old Kerry system. Can Guyson service it for me?
|
A.
|
Most probably, yes. Guyson's Kerry ultrasonic customers in England, Scotland and Wales continue to be supported by experienced local service engineers. Elsewhere in the world service is normally provided by our network of distributors, or by Guyson subsidiaries in Paris, France; Saratoga Springs, New York State, USA; Penang, Malaysia; and Wuxi, China.
For a speedy answer, please email us at service@guyson.co.uk, including if possible the serial number of your machine as well as its name/description.

Q.
|
We need a solvent cleaning system - how can I be sure we don't fall foul of the Solvent Emissions Directive?
|
A.
|
Guyson 'Kerry' Microsolve precision cleaners are designed to use new, low-toxicity solvents with zero OPD (Ozone Depletion Potential). Plus, both our Microsolve ranges, Co-solvent and Mono-solvent, have extremely effective solvent retention features. These systems, correctly used with hydrofluoroethers (3MTM NovecTM HFE) or hydrofluorocarbons (HFCs), are fully compliant with the SED.
|
|
|
| |
Q.
|
I'm cleaning with trichloroethylene and I'm not sure how much longer I can legally continue. Can you help?
|
A.
|
Solvent Emissions Directive legislation is complex, but our engineers can advise you on how the SED applies to your company, and on timescales for compliance if relevant. You will need to let us have details such as how much solvent you are using and the eventual use of the items being cleaned.
|
|
|
| |
Q.
|
We would like to switch to cleaning with solvents but won't it be expensive?
|
A.
|
The new solvents referred to above are certainly more expensive per litre than the older products. However, those solvent retention features which help make Microsolve systems SED-compliant (ie safe for operators and environmentally acceptable) also mean that little solvent is lost to the atmosphere or carried out on components, making the equipment extremely cost-effective in use.
Our Microsolve systems can be fitted with a solvent top-up and monitoring device which allows users to check consumption: 3 litres of HFE (hydrofluoroether) per 40-hour week is typical usage for a
Co-solvent 350 system.
Case histories in News Archives illustrate this - see for instance Monitoring system ensures minimal solvent loss, or Ultrasonic solvent cleaner saves BAe £7,000 a year.

Q.
|
Do you still supply Kerry plastics assembly equipment?
|
A.
|
No - when Kerry Ultrasonics was acquired by Guyson International Ltd, the plastics assembly division was transferred to Sonics & Materials UK Ltd. Enquiries about plastics assembly equipment should be directed to Mr Malcolm Hayward, Sonics & Materials UK Ltd, tel 01449 770055, email sales@sonicsandmaterials.co.uk.
