One parts cleaning system uses various
media
Vacuum Assisted Inorganic Organic Cleaning System by EMO enables chlorinated hydrocarbons, hydrocarbons and modified alcohols to be used in one parts cleaning.
EMO Oberflaechentechnik patented the Vacuum Assisted Inorganic Organic Cleaning System (VAIOCS) in 1995, with which the company said it has revolutionised industrial parts cleaning Today the process is being used in a wide range of cleaning systems

BAe approves EnSolv vapour degreasing
Latest aerospace approval for Enviro Tech Europe's Ensolv 5408 product has been received from BAe and will be added to its R10-6025 Specification for Vapour Degreasing.
They range from 'classic' standard plants to throughfeed systems and large-scale equipment with aqueous and solvent based cleaning steps inside a cleaning chamber.
VAIOCS is claimed to provide a degree of flexibility that was unheard of just a few years ago, said EMO.
VAIOCS enables chlorinated hydrocarbons, hydrocarbons and modified alcohols to be used in one and the same sys- tem for the first time.

When EU legislation is demanding compliance with new demands in so many areas of the process industry, finishing companies are asking how to comply and survive at the same time.
Be vigilant when making degreasing choices
While users are keenly interested in the advantages of process cleaning, they can be confused by the amount of misinformation that seems forever presented to them, writes Derek Carpenter.
Thermal deburring automates gear finishing
Transmissions component manufacturer found that thermal deburring process gave a quick, efficient process that saved the time consuming job of brushing every individual tooth.
In order to achieve the best results when cleaning with hydrocarbons and modified alcohols these systems function at a higher temperature level well above the flashpoint of these cleaning media.
EMO said that the danger of fire or explosion is excluded because the whole cleaning process takes place under a vacuum.
* Optimum degreasing - the higher temperature level not only ensures optimum degreasing results, but is also fast and residual-free drying.
EMO now offers the process technology in combination with aqueous cleaning.
Users can combine aqueous and solvent-based cleaning steps and the whole process works under a vacuum.
It results in a true multi-function cleaning/degreasing process including degreasing, cleaning, preservation and drying.
The cleaning process can also be supported in many different ways using ultrasonics and/or turning or oscillating movements.
Another decisive benefit of this combined process technology is its total flexibility.
Regardless of whether the parts spectrum or the requirements change, with VAIOCS technology the user can adapt it to almost any conceivable conditions at very modest investment costs.
Combined VAIOCS systems can replace investments in two separate systems for aqueous and solvent-based cleaning processes.
The process technology also offers state-of-the-art 'green' technology.
It functions with practically no waste water or exhaust air.
The cleaning media is recycled with practically no losses at all, said EMO.
Permanent purification of cleaning liquids using filters and distilling processes guarantee long system service lives and also ensures economic and environmentally friendly operation.
Classic VAIOCS cleaning systems are described as follows.
* Classic VAIOCS systems - these are offered in two standard sizes, in which the production components are placed in stacking transport boxes in two standard sizes (530 x 320 x 200mm and 670 x 480 x 300mm).
At a maximum basket weight of 80 or 150kg, the throughput rate of systems such as these is somewhere between six and eight baskets/h.
* VAIOCS systems with aqueous media and solvents - the combined systems of the latest generation also work along familiar VAIOCS lines.
Aqueous media and solvents are combined inside a single treatment chamber for the first time.
The user is able to specify any combination of aqueous and solvent-based cleaning cycles for degreasing, cleaning, preservation and drying for removing organic and inorganic contamination.
* VAIOCS throughfeed systems for high rates of throughput - EMO Oberflaechentechnik also offers VAIOCS through- feed parts cleaning systems.
One or two track models clean, degrease and preserve with outstanding cleaning quality, said EMO.
Compared with conventional systems which have to be loaded and unloaded for each and every cleaning operation, EMO said it makes sense to use throughfeed systems whenever the customer is looking for highest levels of throughput and the smooth integration of cleaning systems in production lines whilst simultaneously making a clear separation between the dirty and clean side.
* VAIOCS cleaning systems for tubes - EMO now offers a system for cleaning and degreasing tubes.
The closed system features the tipping of the treatment chambers (which can be up to 30m long) to ensure fast flooding and emptying of the chambers.
The tube cleaning process is divided into a fast 'rough' cleaning process and final precision ultrasonics activated cleaning.
There follows steam degreasing and drying cycles.
All cleaning processes take place in a vacuum.
The benefit of this process is that tubes are cleaned quickly and economically to the very highest standards, said EMO.
* UK installation - during a meeting at the recent MACH 2008 exhibition, EMO sales manager, Thomas Weiss, said that the company had recently delivered a VAIOCS tube cleaning system to Lawton Tube in Coventry.
He said that EMO can build very large VAIOCS machines with chamber size of typically, 1800mm x 900mm x 950mm.
Systems can be top-loading designs, and for large components, or large batch charging, pit systems have also been built.
He added that many EMO customers are heat treatment shops, which have to cope with a variety of contaminents, for which VAICOS is ideal.
* Surface Alliance - in Germany, EMO Oberflaechentechnik (EMO Surface technology) is a member of the Surface Alliance partnership.
As well as EMO, it includes Hoesel and LPW Reinigungssysteme (LPW Cleaning systems).
The product range offered by the Alliance partners is complementary to provide a broad spectrum of indivi- dual systems, which offer the right technology for almost every cleaning task.
In the field of precision and critical cleaning the Surface Alliance offers an optimum system from a single source.
* Water or solvent-based.
* Stand-alone system.
* Integration into a production line.
* Components for treatment can range from small parts to tubes up to 30m long in length.
The Surface Alliance partners - and customers - benefit from combined research and development, purchasing, production, sales and service.
At the same time, the partners maintain a market-oriented independence.
An advantage is the decentralised structure which enables the alliance to respond quickly and flexibly to customer requirements.
