Aqueous cleaning machines

Paul Boughton
Turbex is launching a new range of aqueous cleaning machines, introduced at the start of the year under an exclusive agency agreement with MAFAC.
The machines are distinguished by a system whereby the movements of the holding basket and spray jets are individually adjustable, allowing them to rotate in the same or opposite directions. 

Each program can therefore be tailored, together with other movement options such as rocking of the basket, to clean efficiently even the most complex of parts.
These high quality machines have integral condensing systems, so there is no need for extraction to be fitted.
There are five machines in the MAFAC range, to be represented on the stand by the Elba, which will be under power.  It has a dual wash tank, integrated warm air drying and an easy to use control that stores cleaning programs without complicated codes.  A folding loading door is standard, although a vertical sliding door can be specified for use with automatic basket transfer for unmanned operation.
To be exhibited for the first time at a MACH show will be a compact, ultrasonic cleaning system called Versa from another Turbex supplier, FinnSonic.
The modular, expandable equipment can have any number of tanks, which can be of either 40, 80 or 120 litres capacity.  Typical cleaning processes include ultrasonic or immersed jet cleaning, single or multiple water rinsing and hot air drying.  Particle filtration as well as oil separation can be included, according to customer requirement.  Manual configurations can be specified.
Each tank is operated from a panel linked to a central PLC system, which provides ease of use and also allows retrofitting of handling automation, available for 10kg or 20kg basket weights.  Manual handling by pneumatic assist lift is available for baskets weighing up to 30kg.
A further Turbex aqueous washing machine on show will be the AS-100 from a range of front-loading models that has proved particularly popular in the UK.  Manufactured from stainless steel, the machine is intended for degreasing and cleaning components up to 950 mm across by 700 mm high and weighing a maximum of half a tonne.  Much larger machines are also available, as well as multi-stage configurations with washing and rinsing capable of more thorough cleaning.
Suitable for use in repair and maintenance shops serving transport depots, railyards and marine workshops, for example, the single-stage, spray wash machine is also suited to inter-process cleaning in production environments, such as batch degreasing of machined components and preparing fabrications for welding.
The cleaning medium is detergent dissolved in water heated to 50 to 75 degrees Centigrade, delivered at 400 litrre/min and 4-bar pressure through rotating spray pipes.  In normal operation, the door at the front is lowered with the assistance of two gas springs, one or more components are placed in the work chamber, the door is closed, cycle time and temperature parameters are set on the control and the automatic cycle is started.
An optional lance with its own multi impeller pump can be connected directly to the tank, allowing particularly awkward soils to be removed or temporary use of the equipment as a manual spray booth, without any automatic cleaning.
Acoustic as well as thermal insulation ensure a good working environment.  Optional accessories include a steam extraction fan, automatic refill, an oil skimmer or separator, and a detergent dosing unit.
Completing the machine exhibits will be the CL-360 from the Turbex Classic range of stainless steel, top-loading spray washers.  They provide a compact and economical method of cleaning parts and sub-assemblies in engineering workshops. Ranging from 360 to 1,200mm in diameter, the machines offer excellent value for money for a wide range of applications.
In addition, there will be numerous before-and-after examples on the stand of parts that have been cleaned using various Turbex aqueous washing processes, together with descriptions of the type of soils removed.  The samples will give visitors an accurate idea of the level of cleanliness that they can expect.
