Aqueous Cleaners

For consistently high levels of cleanliness utilising aqueous formats a secure process control is essential.  Whether in-line or batch format, single or multi-step, we offer systems ranging from heavy maintenance and re-manufacture to precision cleaning in high integrity engineering production.  

With so many companies offering aqueous spray wash systems what distinguishes our technology?

Apart from exceptional build quality and wash efficiency, the assurance of repeatable cleaning performance is of paramount importance.  There are many companies who can manufacture a spray wash system specification.  Almost all will demonstrate how well their specification will perform using clean water and chemicals - the true test of performance is how well component cleanliness is maintained days, weeks or even months after system refilling with clean solutions and how efficiently waste residues are removed from the installation.  Disposal costs of contaminated waste water are set to rise and control of ongoing costs will be critical when considering a new installation.

Most wash systems rapidly suffer a deterioration in cleaning performance due to "cross contamination" of various wash and rinse waters.  This is unavoidable without the advanced features of intermediate rinse and counter refill.  It must be remembered that components will (nearly) always be washed with "dirty" water -  the final cleanliness achieved is a function of the quality of the final rinse water which, in high integrity applications can be provided from mains supply (de-mineralised if requirements dictate). 
John Neale Ltd can meet many industrial cleaning tasks throughout the world ranging from high integrity manufacture in aerospace, medical and general precision engineering including Flexible Manufacturing Systems (FMS) to automotive remanufacture and heavy maintenance railway applications.

Typical applications include:

Removal of press and punch oils

Cleaning of cutting fluids following machining operations

Pre-treatment including iron or zinc phosphating prior to powder coating or painting
Removal of lubricating fluids and compounds

Surface cleaning prior to media blasting operations

Removal of heavy road/rail contamination

For optimum performance it is also essential that the right choice of fluid(s) is made to meet each task.  Whether a general degreasing application based on alkaline technology or an acid process such as phosphating, the correct selection and application of chemistry is critical.  However this is just the beginning - as fluids are lost through consumption and evaporation and contamination levels within the system increase, the process would deteriorate if imbalances were not corrected.  Automatic chemical dosing ensures that chemical concentrations are maintained.  In addition, a variety of mechanical filtration options for particulate matter and oil separation  techniques are available to increase solution life expectancy far beyond other processes
