Electrical corrosion protection – Prevent hydrogen sulphide corrosion in electrical and electronic equipment
Super CORR A is a proven and cost-effective way to prevent or inhibit corrosion from destroying electronics and electrical components. Adverse work environments where corrosive gases such as hydrogen sulphide are found, can cause severe corrosion and rapid deterioration of electronic components and equipment, including connectors and switches.
Lost productivity and revenue caused by plant and equipment downtime
Corrosion, in its many forms, costs both private and public sectors hundreds of billions of Euros a year to repair or replace electrical, electronics, or avionic components because of failures caused by corrosion. While all metals corrode, due to a number of different factors, there is no simple or single solution to the overall corrosion problem. However there are some very cost effective and proven ways to prevent corrosion and failures caused by corrosion and thereby reducing or eliminating associated costs and increasing safety which should be foremost in the mind set of any preventative maintenance programme manager.
Super CORR Awas specifically designed to lubricate and prevent corrosion in electrical fittings and connectors; electrical and avionic harness assemblies and connectors; electrical and electronic switches; close tolerance and dissimilar metal components; lighting connectors and sockets. A unique non-flammable “self-healing” ultra-thin film lubricant with a proprietary corrosion preventive compound that will not harden or crack, is not a wax or oil-based product and is formulated without sulphates, chlorides or halogens.
Super CORR A inhibits corrosion caused by exposure to both fresh and salt water moisture as well as the corrosive vapours from Sulphur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulphide (H2S), Ammonia (NH3), and Chlorine (CL12) based gases found in waste water and sewer treatment plants, pulp and paper mills and plants, chemical and petroleum plants, maritime industry, aircraft/airline industry, military equipment including ships, aircraft, and rolling stock, auto industry, farming and agriculture industry, and the list goes on.
Super CORR A extends the working life of electrical components and systems and other critical items by preventing the deterioration and/or failure caused by corrosion and can significantly reduce downtime, operating and maintenance costs as well as enhance safety. An ultra-thin film, water displacing lubricant and corrosion inhibiting compound Super CORR A has undergone extensive testing by Battelle Labs as well as the U.S. Air Force and meets MIL-DTL-87177B (revised MIL-L-87177A) specification. SuperCORR-A is used by NATO (NATO NSN 8030-99-226-6966) to protect avionic, electrical, electronics, electrical switches and connectors and components from corrosion in both the military and civilian aircraft. Savings for the U.S. government alone is estimated to be in excess of $50 million per year.
Super CORR Aprovides 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 (0.00028 inch) thick and is formulated to meet the RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.
The question for you is: What is the cost of NOT using Super CORR A in your preventative maintenance programme?

ProSolv®5408e vapour degreasing solvent cleaner for flushing refrigeration pipeline systems
Vapour degreasing solvent cleaner for flushing refrigeration pipeline systems
Concerns connected with the challenging environmental profile of traditional refrigerant gases have led to changes in legislation which are a driving factor in phase-outs and bans on the use of some gases to remove the older materials typically with high ozone depletion (ODP) and global warming potential (GWP). Systems can be replaced or refurbished with new models using compressors able to use more sustainable and acceptable gases. The evolving trend to newer refrigerants continues as the chemistries develop. The refrigerant R-22, which itself was an improvement over earlier refrigerants, is phased out and replaced with R-410a and other alternatives based on HFOs are being marketed.
Retrofitting of current refrigeration systems to accommodate the new developments is not straightforward as most refrigerant gases are not cross-compatible, so the necessity to completely remove all traces of the older versions from the system, including refrigerant lines is essential.
Of course, where possible it’s best simply to replace existing lines with new ones. However, it’s not always possible to do this cost-effectively, especially when the old piping runs under floors or through walls. In such cases thoroughly flushing existing pipework is especially important because even tiny traces of impurities left in the lines can damage new equipment and lead to compressor failure.
THE PERFECT SOLVENT FOR FLUSH CLEANING REFRIGERATION PIPEWORK
Your first step to proper pipework flushing is to select the right solvent. The solvent you choose must be highly effective at dissolving oil grease and other contaminants, to ensure that all residue is removed from the pipes and must be sustainable, environmentally friendly and comply with current legislation.
ProSolv 5408e is the ideal solution to this problem with a profile of properties and advantages making it perfect as your solvent of choice for refrigerant pipeline flushing.
• No flash point Non flammable liquid.
• High specific gravity gives a high soil suspension loading.
• High solvency strength with a KB value of 98.
• Powerful cleaning agent that can flush lines fast, dissolving oil and grease releasing soils from the inner surfaces of pipelines and fittings
• Volatile for fast evaporation. Removing ALL solvent from the pipework after flushing is vital, very volatile so evaporates fast.
• Environmentally responsible. ProSolv 5408e is sustainable and kind to the environment with very low global warming potential, zero ozone depleting potential (ODP).
• Safe for operators when user conditions are followed.
• Economical as it is easily distilled for reuse. No testing or stabilisation required.
PROCEDURE FOR FLUSH CLEANING REFRIGERANT PIPELINES WITH ProSolv®5408e
Of course, simply replacing old piping is the only way to be 100 percent sure that your lines are clean. But in retrofit situations where complete replacement is not possible, flushing the lines with ProSolv 5408e solvent is the best alternative solution for the protection and long working life of your refrigeration system upgrade.
1 – Remove any obstacles. Any equipment and components such as valve, filters and expansion valves that might obstruct the line should be removed prior to the purge.
2 – Pre-flush. This will dislodge any loose debris from the sides of the lines enabling more effective use of the solvent, oil free air or nitrogen at 120 psi is recommended. It’s also good practice to oscillate the pressure to encourage dislodging of debris.
3 – Preparing the pipework. Reducing the length of piping can be more effective due to the pressure loss in long lengths. Section the operation into 15 metre lengths by cutting pipes where necessary. One end of the pipe must be fitted with a connector for the pipe to the nitrogen supply while the exit needs a restrictor valve to allow variable pressures to shock loose particles from internal walls.
IMPORTANT – Flushing with solvent. Refer to ProSolv 5408e Safety Data Sheets for advice on operator protection using solvents.
4 – Safe working. Full PPE with suitable eye protection goggles and gloves must be worn. Solvent fumes are heavier than air and exposure levels can easily be reached working in pits or enclosed spaces. Always institute a ‘buddy system’ and use air fed face masks with attached line.
5 – Delivering solvent. Use a drum pump electric or hand operated with a flexible tube connection for delivering the solvent to the open end of the pipe or tubing to flush the internal surfaces. Using a fresh drum of ProSolv®5408e connect drum pump and the delivery tube to the end of pipe/tube to be cleaned using a pre-fitted screwed or compression fitting.
6 – Drainage and Testing. The drainage end of the pipe or tube should be fitted with a flexible tube into a tank or drain sump allowing samples to be taken in a glass bottle or tube at regular intervals to be sure when no particles or soils are being expelled. The colour of the solvent will change as oil and soluble contaminants are removed and flushing must continue until the flow is totally clear and water white.
7 – Post-flush. ProSolv 5408e solvent is volatile so will dry completely using an oil free airline or nitrogen supply connected to the end of the cleaned pipe/tubing.
8 – A wipe of the pipe/tubing surface at the inlet and outlet using solvent saturated lint free cloth completes the cleaning. If not connected immediately to other parts of the system enclose both ends of cleaned item to prevent recontamination.
Used ProSolv 5408e should not be reused for flushing but can be recovered for reuse by a simple distillation process. Removal from site should use licensed disposal companies.

An ounce of protection is worth a pound of cure
“An ounce of prevention is worth a pound of cure.”
Benjamin Franklin said that in 1736 and it is as true today as it was then.
One of the most important opportunities for savings today is the prevention of failures caused by corrosion. Corrosion leading to the repair of or the complete re-placement of failed parts or components, a pound of cure, which is preventable, equates to increased production costs and a decrease in the bottom line profits.
SuperCORR A is the ounce of prevention that will save your company money; man hour costs and parts in the re-pair or replacement of equipment that failed because of corrosion issues that are easily preventable. Whether it’s an electrical connection that failed because of corrosion which caused a cooling pump to shut down that caused a bearing to overheat and burn out that brought an entire production line to a halt or it’s the floor of an airliner that was so corroded that the aircraft was grounded for extensive repairs, corrosion is a serious and a very expensive problem. A problem that is preventable.
An ultra thin-film lubricant with corrosion preventative compounds that displaces water, SuperCORR A has been extensively tested on metals and electronics and has shown extremely good results in preventing corrosion.
The question to ask yourself is: What is the cost of NOT using SuperCORR A to prevent corrosion?
If you were able to say we are saving £100 a day by using SuperCORR A by not having a failure caused by corrosion would that be a good thing? How about saving a £1000 a day? A saving that would directly influence the bottom line.
You have essentially two choices:
1). Being proactive about corrosion and doing something simple and very cost effective to prevent it,
2). Do nothing and take your chances that the cause and the associated costs of the next lost production time are not directly related to a preventable corrosion problem.
Being proactive about corrosion and doing something that is cost effective and protects the bottom line is nothing but a positive. Remember the cost of lost productivity is directly related to lost profits.
CORR-EX corrosion control solutions have the answer to corrosion prevention for all industries and utilities.

See how SuperCORR A can save money and time changing light bulbs
Question – How many engineers does it take to change a lightbulb?
Answer – One,
but they’ll spend three hours checking it for alignment and leaks.
There are thousands of jokes on this theme but anywhere, factories, offices, warehouses, supermarkets, sports stadiums, railway stations, ocean liners, road lighting and other applications where thousands of light fittings are installed it can be a major maintenance expense rather than a joke.
SuperCORR A is a corrosion preventative dry lubricant aerosol which rejects water and protects the bulb socket and fitting and prevents sticking. This makes bulb changing easy and quick.

SuperCorr A defeats increasing gold prices for connector manufacture
Thinner plating caused problems with increased corrosion on USB connectors as gold coating thickness decreased with escalating gold prices.
A major company in the U.S. found that by using SuperCORR A it was able to prevent galling corrosion due to vibration on printed circuit leads and connectors.
They found that because of the advances in gold plating technology the plating thickness was being reduced over the base substrate metal of the connectors. The thickness of the gold plating became thinner and thinner over time. This thinner coating saved a lot of money as gold was and is becoming increasingly expensive. However the resulting reduced thickness of gold plating also resulted in failures caused by corrosion. Minute irregularities in the surface of the connectors base metal caused irregular or uneven wear of the connector causing the “high spots” on the connector to wear through the gold plating.
Using SuperCORR A prevented or delayed the corrosion and subsequent failures. However it must be recognized that
SuperCORR A is a lubricant with corrosion preventive compounds, and as is the case with all “lubricants” they will be worn off over time. Having said that, the Company also had SuperCORR A tested 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 USB connectors at all. In fact they commented that the USB connector looked as good as new.

Corrosion Control
Corrosion is a serious problem for industry and governments worldwide. Most people associate corrosion with rust, which only happens in things made of ferrous metals such as steel girders, ships, iron pipes, steel reinforcement rods, and steel tanks and is the reason metals deteriorate and fail.
Ferrous and non-ferrous metals corrode on contact with both fresh and salt water as well as water vapor. They will also corrode when they come in contact with chemicals, liquid acids as well as acidic vapors, salts and bases, and bacteria.
Read our article “Corrosion Control Solutions – A Solution To A Costly Problem” for more information about the enormity of the costs involved in failing to prevent corrosion.
