Vapour degreasing solvent for precision parts cleaning

precision parts cleaning

EnSolv® CC-A vapour degreasing solvent for precision parts cleaning

The EnSolv® CC-A formulation for precision parts cleaning responds to the need for high performance vapour degreasing solvents for critical cleaning in general engineering, aerospace, medical optical and electrical industries.

EnSolv® CC-A removes cutting oils, lubricants, lapping compounds grinding pastes and water based cutting oils or fluids. This complex synergistic blend utilises environmentally compliant solvents combined with selected surfactants to remove oils and lubricants to the highest standards for critical cleaning applications and releases and suspends inorganic solids and soils such as fingerprints, polishing compounds and grinding paste from finely finished and highly polished surfaces such as stainless steel and plated parts, optical lenses and components for medical appliances.

IMPROVES PRODUCTIVITY AND OPERATING ENVIRONMENT

Suitable for processing temperature sensitive components as well as the conventional engineering substrates. The very low surface tension cleans through holes on castings and penetrates between overlapping metal spot welds eliminating oil leaching in paint and powder coatings during oven curing.
Easy handling – Cleaned components are dry and comfortable to handle immediately at the ideal temperature for painting or powder coating. No time lost waiting for parts to cool which allows immediate quality control testing or assembly of machined parts due to minimal dimensional changes.

Cleaning cycles reduced, productivity improved with output doubled compared to conventional solvents.
Minimises flash rusting on mild steel cleaned components due to the advanced stabiliser/inhibitor package compared to alternative formulations.

Compatible with mixed metal components. No staining of yellow metals, bronze, copper, aluminium.
Reduced maintenance – unique additive suspends contaminants in boiling solvent sump preventing tar formation and continuously cleans heating surfaces. Longer periods between cleanouts reduces labour costs and solvent losses.

Talk to us about whether EnSolv® CC-A  is the best choice for your application. Advice, literature, changeover instructions are all available to make the change quickly, easily and at no extra cost of usage.

Corrosion protection – Reduce fretting corrosion

Reduce fretting corrosion

Corrosion protection – SuperCORR A helps to reduce fretting corrosion on gas turbine connectors.

LP Gas Turbines are used throughout the world by extraction industries and manufacturing plants in remote and hostile locations for essential power production. Dusty and wet environments in deserts, mines, grinding mills, pulp and paper mills and on land or sea drilling rigs for gas and oil production. Turbines powering aircraft services while stationary connect and disconnect many times a day in extreme conditions. These applications and locations test connector sealing continuously allowing dust or water to penetrate. This with the flexing of the connecting cables allows sufficient movement between the metal surfaces of the connecting pins to produce fretting corrosion which reduces, interrupts or produces failures in supply. Regular maintenance of electrical connectors is essential to be certain of uninterrupted supply.

RUB TEST RESULTS
Super CORR A  is an aerosol lubricant containing corrosion preventive compounds.
A manufacturer of connectors tested Super CORR A to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the connectors at all. The connector looked and tested as good as new. This test was run under clean conditions in a laboratory but demonstrates the effectiveness Super CORR A.

As it meets Mil MIL-DTL-87177B (revised MIL-L-87177A) specifications it is used by the U.S. Air Force to protect the intricate workings of the F-16 and F-15 fighter jets and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for avionics and electrical switches and connectors and close mechanical application, especially where flights are in salt fog or high humidity.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors Super CORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electromigration problems. The super thin non-flammable lubricant film is only 7 microns (0.007mm) thick and is formulated without sulphates, chlorides or halogens to meet the RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.

Very fast drying, environmentally acceptable solvents are used as carriers and propellants which will not affect most plastics, substrates, metals or other materials used in connector manufacture. The aerosols are supplied with probes which allow access to pins and connector tubes where the low surface tension repels water, dirt dust and metal particles from blind holes and surfaces to produce thoroughly clean holes and surfaces before a second application applies the lubricant film. Reconnection to the supply with cleaned sections of the connector ensures reliable operation even in the most testing of environments. One can of Super CORR A allows this essential task to be carried out in any conditions quickly, easily and securely.

Eliminate bad smells using unique concentrated water based cleaning system

Eliminate bad smells

Aquus® CL-One is the ALL purpose concentrated cleaning system based on an innovative formulation of surfactants which also controls odours and will eliminate bad smells at source.

The unique combination of properties exhibited by Aquus CL-One offers excellent emulsion-breaking capability in addition to its unusual combination of properties that makes it so attractive for a wide range of industrial applications including an unusual application which is discussed below in more detail, utilising these properties to control odours and eliminate bad smells at source.

CONTROL ODOUR BY ELIMINATING UNPLEASANT SMELLS AT SOURCE

Aquus CL-One eliminates odour problems caused by bacteria and other organisms. No fragrance or other masking agents are used, the odour is very effectively eliminated at source. Conventional masking agents use fragrances or enzymes which act slowly and are less effective and more expensive than the Aquus CL-One alternative which uses a totally different approach to these problems.

MANY APPLICATIONS FOR ODOUR CONTROL

Odour control is needed where cleaning is performed in food preparation, processing equipment and containers, sewage treatment plants and in other waste-water facilities.

VOLATILE ORGANIC COMPOUNDS

Aquus CL-One breaks down the organic compounds responsible for the release of the volatile organic compounds (VOCs) producing the unpleasant smells associated with some commercial and industrial processes and systems.

Aquus CL-One eliminates the ability for bacteria to produce the odour producing VOCs by disrupting the integrity of the cell walls.  Odour producing microorganisms have cell walls made up of organic materials including lipids (fats). The alkalinity and surface-active ingredients of the Aquus formula breaks down the cell walls of the organism which protect the inner workings. Once compromised the bacteria can no longer absorb nutrients and eliminate waste. This kills the organism which then cannot generate the VOCs which produce the smells.

ADVANTAGES OVER OTHER METHODS

Aquus CL-One has considerable advantages over the toxic, fragrance or enzyme based alternative odour control products which only mask the smells. Enzyme based formulas need regular maintenance to keep the enzymes active and work slowly. Masking agents are usually ineffective and expensive.

Aquus CL-One eliminates completely the odours and smells associated with these organic materials including bacteria and other organisms simply and effectively.

Some examples of controlling bacteria related odours –

ENGINEERING WASTEWATER TREATMENT SYSTEMS

Aquus CL-One is extremely effective in separating oil, water, and solids in drains, conveyor traps and sumps on automatic honing, turning and grinding machines when using water-based lubricant and cooling liquids.

Emulsions are broken allowing cleaned metal dust, shavings and dirt to precipitate to the bottom, the solution of Aquus CL-One and water retains the active cleaner in the middle layer, oil and grease float to the top. The efficiency of oil/water separators in plant waste treatment systems are significantly increased while the disposal of toxic waste is greatly reduced.

FARMING AND AGRICULTURE   

FARMING AND AGRICULTURE    Farming and agriculture require reliable water-based cleaners for the innumerable cleaning applications needed particularly where animal husbandry is involved. Scrupulous cleaning of surfaces on rails, floors and walls is essential for the health of the animals. The unique bacterial destruction abilities described earlier is very effective in odour control in many farming applications

Aquus CL-One is the concentrated water activated cleaner which is used at different dilutions to meet the requirements of the many applications and challenges met in farming and agriculture. Aquus CL-One which is completely biodegradable within 30/40 days, is not toxic and not considered a hazard which is particularly important in sensitive environmental sites and situations. Safe for use with any application equipment such as high or low-pressure washers, spray washers or dip tanks it can be used with mops, brooms etc by operators without needing personal protective clothing.

The unique combination of oleophilic and hydrophilic properties encourage sedimentation of solids from liquids in wastewater separation tanks and as the cleaner solution can be recycled and reused until biodegradability reduces its effectiveness it is very economical in use. As an example, in normal use a one litre bottle is mixed with 40 litres of water to activate the cleaning solution which in turn can be recycled many times.

HOSPITALS AND HEALTHCARE  

HOSPITALS AND HEALTHCARE   Cleaning of soiled and contaminated surfaces in hospitals, nursing homes and other medical facilities is essential to control bacterial contamination. Aquus CL-One cleaner can be used for all cleaning applications which reduces time and costs by removing the need for multiple cleaning products usually needed to deal with the challenges presented by the wide range of soils, oils, blood, body liquids and other contaminants which need to be removed.

Aquus CL-One is safe for the environment and users, contains no solvents and is biodegradable within 30 days. With only one product for all cleaning applications incorrect selection or dangerous uses can be avoided.

Vapour degreasing – A simple guide for production engineers

vapour degreasing

This simple guide for production engineers discusses why vapour degreasing is the most effective and economical process for cleaning of manufactured components.

Now is a good time to review your existing cleaning processes or upgrade current equipment. In the autumn Budget 2021, the Chancellor, Rishi Sunak, announced an extension of the temporary increase in Capital allowances which allow the cost of capital assets to be written off against taxable income. The 130% super-deduction and 50% first-year allowance are very generous but only available for a short time. This will allow companies to not only lower their corporation tax bills but improve productivity and reduce operating costs for cleaning processes.Vapour degreasing is the simplest but most effective degreasing and cleaning process which, until recently, has been subject to little change since it was first invented in the early part of the last century. This is a very mature chemical technology which legislation is now effecting changes so fundamental that the more accurate name for the process “Condensation Cleaning” should be used to reflect the improvements in equipment design, chemistry, reduced emissions, economies in usage of solvents and the subsequent environmental acceptability compared to the open topped tanks so ubiquitous in factories and workshops worldwide. The alternatives in equipment design offer differences in technology, which guarantee the continuing use of this process in the future, need to be considered and understood.

cleaning tank The cleaning tank in the corner of most engineering shops hides a very well researched process using sophisticated chemistry. Its popularity is in its simplicity. The tank sump is heated, fitted with cold coils around the internal surfaces at the top to retain the vapour.  Fill to a few centimetres with a non-flammable solvent able to dissolve contaminants, boil to form a vapour 3 to 4 times heavier than air to fill the tank. Hot solvent vapour condenses on the cooler target parts at workplace temperature. The hot liquid solvent dissolves oil and grease and other contaminants. Used solvent returned to the sump revaporises continuing the cycle until parts have achieved the same temperature as the vapour when, with no further condensation, the process is complete. Simple but perfect. Highly productive and economical, parts removed from the cleaning process are clean, warm, and dry in 5 to 10 minutes.

Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour heavier than air at a temperature greater than ambient.

In Europe, the United States and in other advanced industrialised economies increasingly stringent legislation to control emissions of VOCs, especially solvents, has led to new formulations for paints and other coatings where water replaces most of the solvent. In the early days the quality of water-based paints was not as good as traditional solvent-based coatings, but innovation has driven the development of new polymers with results as good as, if not better than, the solvent-based originals.

As with coatings, cleaning systems have had to change. With increasingly demanding standards of cleaning required for precision engineering, electronics, optics etc solvents are often first choice, for reasons outlined above, but these have been targeted by regulators and alternatives are encouraged by the relevant authorities and law makers often without serious consideration of unintended consequences.

For example, water-based cleaning is encouraged as the obvious alternative, but this has many disadvantages compared to condensation cleaning as although the machines are simple and relatively cheap the processes require multiple heated tanks for immersion or spray processing or long programmed cycles in batch machines for cleaning, rinsing, and drying. Water based processes are slow, energy intensive and occupy more floor space than solvent-based condensation cleaning equivalents where only one tank with a small footprint is needed, delivering shorter process times and, most importantly for the environment, using minimal energy.

The ideal cleaning process would be “Condensation Cleaning” using water but due to the physical characteristics of the water vapour/steam and the inability to carry onto the surface of the targeted parts surfactants to remove the oil, grease and soils and the difficulty and expense of rinsing and especially drying this can only ever be a dream.

Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour three to four heavier than air at a temperature greater than ambient.

The traditional solvents such as trichloroethylene exhibits all these characteristics however concerns about its carcinogenic properties and the danger to operators by exposure, led to a continuing search for a safer alternative. 1,1,1 trichloroethane based solvent formulations became popular in the mid part of the last century as a safer replacement. An excellent solvent, safer for users, it proved to be depleting the protective ozone layer around the Earth and was subsequently banned. With the development of the REACH legislation in Europe, trichloroethylene was again allowed with restrictions and stringent controls for use in authorised machines which control emissions to very low figures close to zero.

EnviroTech have been supplying vapour degreasing solvent formulations for 40 years constantly responding to increasingly stringent regulatory requirements for environmental and safety laws and the need for improved cleaning standards.

ProSolv® 5408e is a new sustainable solvent blend with near zero OPD (Ozone Depletion Potential) and GWP (Global Warming Potential) for high performance degreasing and cleaning which ticks all the boxes with the perfect profile for a vapour degreasing solvent. Soft on the environment and safer for users with high performance, improved cleaning, and lower costs. Lower boiling point, economical with energy with low solvent losses, faster production, reduced costs, easy handling. Exceptionally low surface tension to penetrate micron sized holes and close contact surfaces. Sustainable and secure for future use as your ‘forever solvent’.

As with all legislation for chemical use regulation and restrictions drive development of associated processes and equipment. Sealed tanks are now standard with many different designs available. The most common are discussed below.

The single tank hermetically sealed machines favoured by some manufacturers uses a process tank to contain the solvent and a separate storage tank/vapour generator. Baskets loaded with parts to be cleaned are introduced from the top or through access points on the side of the tank. Lids or doors hermetically seal the tank. Solvent is pumped into the process tank where agitation, ultrasonics or pumped liquid is circulated through the parts. Used Solvent is removed to the vapour generator, condensing coils controlling the vapour are linked to coils located in the vapour zone which, when the cycle is complete, collapse the vapour.  The process tank is emptied. Controlled air introduced to process tank is then recycled through carbon absorption units to remove traces of solvent until the concentration is within regulatory standards when the lid is released for the basket of parts, clean and dry, to be removed and replaced with a further basket.

Variations of process within the hermetically sealed tank are possible using sprays of cold or hot condensed solvent, immersion with or without ultrasonics and revolving baskets to cover most of the problems experienced when processing machined and fabricated parts. Continuous external distillation of the contents of the vapour generator is also an option depending on contamination.

The alternative technology is much simpler and uses well tried techniques not requiring the long recovery times of the hermetically vacuum sealed processes. The multilevel system uses a standard vapour degreasing tank design with a sealed loading section above the process tank. Components to be cleaned loaded in work baskets or jigs are fed to the load section by hand or conveyor, an internal platform raises and lowers the baskets in controlled cycles.

Loading complete – the load enclosure is sealed to completely isolate the process. Then seal on the process tank is opened and the basket automatically lowered into the cleaning section which can be simple condensation cleaning or immersion cleaning with or without ultrasonics or power sprays. Revolving baskets can also be added to improve cleaning in blind or through holes or oil ways in castings and fabrications.

On completion the basket rises to the area where the condensation coils are located, and parts allowed to drain and dry, basket raises into the load section when the process tank is sealed. A fan circulates air within the load area which can be recycled through carbon absorption systems if no external exhaust is preferred.

As baskets entering the loading space contain parts drained and dried only very small amounts of solvent are carried in the exhausted air which is monitored to ensure compliance with appropriate legislation. When this is complete the seal opens fully for removal of cleaned components. The loading section can be fitted with top or side seals allowing baskets to flow through on conveyor systems or be removed by hand or hoist. No solvent enters the work area.

Both processes will produce parts cleaned to the highest standards but the choice of which offers the best solution needs a little more consideration.

The hermetically sealed vacuum process is complicated with the need to move liquids in the machine. It is relatively slow as the carbon adsorption process has to remove high levels of solvent from the recirculated airstream from the process tank. This is inefficient as adsorption rates for carbon fall rapidly with increasing saturation.  Final levels of solvent in the tank when the lid or loading door opens will be dragged into the workshop and the area where the operator is working. Long process cycles reduce throughput.

The simpler multilevel systems where movement of liquids is not required are more efficient and offer much faster process times.  Cost of manufacture is also reduced as no liquid movement or vacuum is involved. The extracted loading section ensures no leakage of solvent into the work area giving complete safety for operators and factory staff.

Both designs of process machines fully comply with the emission regulations of the EU and U.S authorities. Which to choose will depend on many factors which should be discussed with equipment and solvent suppliers who have the experience to advise on which offers the best process for the application. Equipment and solvent must work together, so it is advisable to ensure that the suppliers co-operate to offer a package with high levels of responsible care and product stewardship to ensure the best and safest installation. EnviroTech personnel and distributors are trained to work with our equipment suppliers to advise on the use of ProSolv® 5408e for the most satisfactory outcome.

Condensation cleaningThe “Condensation cleaning” process still gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage and environmental impact. With the new generation of sealed cleaning machines its future as the process of choice is assured.

Vapour degreasing solvent for precision metal cleaning

precision metal cleaning

EnSolv® CC-A Vapour degreasing solvent for precision metal cleaning

The EnSolv® CC-A formulation for precision metal cleaning responds to the need for high performance vapour degreasing solvents for critical cleaning in general engineering, aerospace, medical optical and electrical industries.

EnSolv® CC-A  removes cutting oils, lubricants, lapping compounds grinding pastes and water based cutting oils or fluids. This complex synergistic blend utilises environmentally compliant solvents combined with selected surfactants to remove oils and lubricants to the highest standards for critical cleaning applications and releases and suspends inorganic solids and soils such as fingerprints, polishing compounds and grinding paste from finely finished and highly polished surfaces such as stainless steel and plated parts, optical lenses and components for medical appliances.

EnSolv® CC-A is a proprietary blend of inhibitors and stabilisers for the solvents to prevent water staining and corrosion of yellow metals such as copper, brass and bronze which can be a problem with some other solvents.

EnSolv® CC-A is non-flammable, stable and specifically formulated for use in any vapour degreasing equipment with the added advantage of lower solvent usage, greater stability and reduced costs. The formulation is compliant with all current environmental and user safety legislation.
