John Neale Ltd
Precision Engineered Lubricants
All solvent systems are fully compliant with environmental legislation including 1999/13/EC The “Solvent Emissions Directive”, The Solvent Emissions (England & Wales) Regulations 2004 and the forthcoming EuroNorm 12921.
John Neale Ltd offers metal cleaning and surface finishing with consistently high levels of surface cleanliness as well as processes for other materials including plastics glass and PCB cleaning.
The extensive range of solvent technologies includes systems and processes for very large scale solvent cleaning requirements including tube cleaning and heavy maintenance applications. John Neale Ltd offers a unique approach to this particular market by ensuring that the selected solvent is fully capable of removing the soils in question. For instance modified alcohols are very good with some soil types but very poor when trying to clean polymeric lubricants of olefin nature used in aluminium and non-
With so many options available in today’s market we also offer cleaning and degreasing consultancy in order that the best format is chosen.
Low surface tension (typically 25-
Solvents can generally accommodate a wide range of contaminants whereas aqueous detergents are usually “soil specific” and a variety of chemicals may be required to be effective in many manufacturing processes.
The separate distillation within an hermetically sealed solvent system ensures that both clean liquid and pure vapour are available for each cycle therefore maintaining consistent results.
The volatility of organic solvents ensures that thorough drying of metal component parts is both rapid and thorough. Compare the latent heat of evaporation of water at 2280kj/kg with organic solvents at approximately 200-
By applying a vacuum to the process chamber and therefore reducing the boiling point, residual component heat will ensure instant vapourisation allowing up to 10 cleaning cycles per hour.
Hermetically sealed solvent cleaning technology ensures that all contamination is isolated in the distillation unit, no longer are we disposing of vast amounts of “dirty solvent”.
