A guide to critical cleaning of oxygen components and services
Guide to critical cleaning of oxygen components
The COVID pandemic of 2020-2023 increased the demand for critical cleaning of oxygen components to treat patients with symptoms. The need for respirators and installation of new and extended oxygen systems in hospitals, clinics and care homes with the provision of ancillary pressure reduction and delivery systems led to a massive increase in demand for the valves, fittings and pipelines which control the supplies from storage tanks and cylinders, all of which needed critical cleaning.
CLEANING OXYGEN COMPONENTS
Critical cleaning of oxygen components is a crucial process to ensure the safety and reliability of systems that handle oxygen, especially in industries like aerospace, healthcare, and industrial gas production.
Cleaning for oxygen service is best defined as the removal of combustible contaminants from the surface of any equipment or system in oxygen service. Essentially, any component that may encounter an oxygen rich environment. The combustible contaminants include organic and inorganic substances such as hydrocarbon material for example oils and greases, paper, fibre, dust, and soils. If these contaminants are not removed properly, in a worst-case scenario, this can cause combustion or explosion in an oxygen atmosphere or at the least rejection of the product due to unacceptable product purity.
Oxygen is not flammable, but it supports combustion. Oxygen can react with most materials. The higher the oxygen content and/or pressure in a system the more vigorous the combustion and the lower the ignition temperature required. Materials that do not normally ignite in air will burn and may explode in an oxygen rich environment. In addition, the oxygen rich environment will give rise to a higher flame temperatures and combustion velocity with potentially devastating consequences. The recognition of oxygen’s reactivity has led to stringent requirements regarding the cleanliness of equipment in oxygen service. Strict guidelines exist to ensure that care must be taken in the selection of equipment including all materials and components, which all need to be oxygen compatible. They must also be free from combustible contaminants as described above.
Consideration must be given to any cleaning processes employed in the manufacture and maintenance of all components of oxygen service systems. There are many options depending on the type of contaminants from aqueous to semi aqueous and blasting systems, to removal of welding slag etc. These are all referenced in the section below.
INDUSTRY STANDARDS FOR OXYGEN SERVICE CLEANING
As part of the programme of worldwide harmonisation of industry standards, the ‘European Industrial Gases Association’, (EIGA) published Cleaning of equipment for Oxygen Service Doc 33/18. The publication was developed from the Compressed Gas Association Document G-4.1 Cleaning Equipment for Oxygen Service by the ‘Compressed Gas Association’.
Specific consideration must be given to the following:
- Cleaning standard to be achieved (how clean is clean?).
- Cleaning procedure.
- Solvent cleaner to be used.
- Surface properties of the parts to be cleaned.
- Shape and geometry of the material.
- Types and amounts of contaminants.
- The degree of automation required.
The size and capacity of the equipment is determined by:
- The size of the material or components to be cleaned.
- The required throughput.
Your starting point should be the cleaning standard and procedure. Solvent cleaning and solvent vapour phase cleaning of components consists of the removal of contaminants by immersion in the solvent, possibly with the addition of ultrasonic agitation and the action of continued condensation of solvent vapour on the component surfaces. The procedure requires that the oxygen equipment, system or component is colder than the solvent boiling point. This allows the vapour to condense on the components and perform a final rinse.
The major significant advantage of solvent cleaning is that vaporised solvent is always pure, and the contaminants remain in the boiling liquid section which requires only periodic cleaning out, thus causing a reduction in the frequency of system downtime. The effectiveness of a particular cleaning agent depends upon the method used, the nature and type of the contaminants and the characteristics of the article being cleaned, such as size, shape, and material. Final evaluation of the cleaning agent should include testing of actual products and production processes. All equipment must, together with the cleaning chemistry, comply as a minimum with current legislation for health, safety and environment. The efficiency is controlled by utilising typical samples, written procedures and requested criteria for cleanliness.

Corrosion control for extreme conditions
Preventing disaster with corrosion control – lt is clear that the use of SuperCORR A for corrosion control can bring financial savings in reduced maintenance and replacement costs and more importantly greater safety.
Most people associate corrosion control 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 saltwater as well as water vapour. They will also corrode when they come into contact with chemicals, liquid acids as well as acidic vapours, salts and bases, and bacteria.
Corrosion is also a problem in electronics from circuit breakers and contactors to wire bond connectors and soldered components on a printed circuit board. Electrical connectors and plugs are very prone to corrosion as well as non-ferrous metals and alloys such as copper and aluminium. For purposes here, corrosion can be defined as a chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.
Corrosion is an increasingly serious and costly problem that can lead to plant and equipment failures which range from being an annoyance to being catastrophic. Failures caused by corrosion could and do lead to a direct failure of a component which could affect the entire system and can not only be very expensive in terms of down time to repair or replace plant and equipment, but can also prove to be very costly in loss of productivity but to human life.

B: Untreated section
C: Treated with SuperCORR A, demonstrating its superior performance.
Preventing disaster with corrosion control – Electrical component failure
If an electrical component fails that affects your car that is just an annoyance and can be repaired fairly inexpensively and if you’re driving the car rolls to a stop and you get out. However, if an electrical system failed because of a corroded electrical contact in a control circuit which caused another electrical failure in the master fuel control system on an airliner at 30,000 feet with 250 people on board that could prove to be catastrophic. While the electrical contacts in both cases failed due to corrosion both failures could very well have been prevented by using SuperCORR A in a Corrosion Prevention Program incorporated into all routine maintenance programs.
“Self-healing” ultra-thin film barrier

It is much simpler and a lot less costly to prevent corrosion than to repair or replace the damaged equipment or component that failed because of corrosion. The photographs show the effects of protecting metal surfaces and components in extreme condition with a SuperCORR A aerosol.
SuperCORR A is a non-conductive, non- flammable, hydrophobic, ultra-thin film lubricant and corrosion preventive compound. It is a “self-healing” ultra-thin coating that lubricates and protects metals, motors, electrical and electronic components from moisture, salts, chlorides, acids, and oxidation.
Corrosion of electrical components is very prevalent problem and one that can be prevented. Preventing moisture from coming in to contact with the electrical components is the key. An ultra-thin film of SuperCORR A will not only prevent moisture from coming in to contact but will displace moisture that is there already.
SuperCORR A is hydrophobic, that is it repels water and forms a “self-healing” ultra-thin film barrier that prevents moisture from coming into contact with the coated electronic components.

Ideally suited for cleaning protective coatings, grease and soils from used or parts during manufacturing processes. Aquus CL-One can be used in parts washing equipment or dipping tanks without modifications and leaves no residue after drying.
Oil and grease separate from the water and coalesces on the surface of the cleaning solution which can then be skimmed off for recovery and recycling. Precipitated solids free of hydrocarbons can be removed by settlement or in filtration systems. The cleaning solution can be reused continuously within its chemical effectiveness parameters for efficient and economical use.
GENERAL CLEANING
Aquus CL-One is remarkably efficient removing oils, greases, and accompanying dirt from most surfaces. It can be applied by wiping surfaces, mopping floors or in rotary floor cleaning machines, or by low or high-pressure spray. Aquus CL-One is also an effective cleaner in industrial kitchens removing grease and baked on deposits on internal surfaces of ovens and trays. For maintenance of machines, engines etc oil and grease is easily removed pre and post assembly making inspection and repair easier, quicker and cheaper by returning equipment to use.
PREPARATION FOR PAINTING OR POWDER COATING
Aquus CL-One is an excellent choice for cleaning mild steel and ferrous metal parts which are not painted immediately. Process oils and grease on the parts protect the surfaces from changes in humidity but once removed flash rusting can occur while drying. Aquus CL-One prevents this leaving an invisible barrier on the metal surfaces providing extended corrosion protection during storage, fabrication or assembly before finishing. The barrier film can be painted over without additional rinsing and without affecting adhesion of paint or powder coatings. Any cleaning system can be used hand wiping, dip tanks, or pressure washing.
WASTE TREATMENT SYSTEMS
Aquus CL-One is extremely effective in separating oil, water, and solids in drains and conveyor traps and sumps on automatic honing, turning and grinding machines when using water based lubricant and cooling liquids. The 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, and oil and grease float to the top. The efficiency of oil/water separators in plant waste treatment systems are significantly increased while the amount of toxic waste requiring disposal after treatment is significantly reduced. The cleaning solution can be reused to treat more waste streams until biodegradation occurs and it no longer operates effectively.

Tried And Tested Vapour Degreasing Solvent For Critical Cleaning
CONTENT ON THIS PAGE IS RETAINED FOR INFORMATION ONLY
DUE TO n-Propyl bromide now being included in Annex 14 of REACH
EnviroTech Europe Ltd (ETE) continue to publish it as historical information and to record changes occurring in legislation which have affected decisions on formulations and equipment used in vapour degreasing - the most effective, quickest, flexible and cheapest cleaning system used in industry.
EnSolv® invented and patented by EnviroTech has been a market leader all over the world for vapour degreasing. It is based on n-bromopropane (nPB) which now cannot be used as a vapour degreaser within the UK or EU without authorisation.
Archived information about EnSolv® can be found using the Discontinued Products & Resources navigation menu on this page.
Using experience accumulated over 40 years supplying and supporting users of the vapour degreasing process ETE specialists have developed “drop in” alternatives:
ProSolv®, ProSolv5408e® and EnSolv CC-A® give the same or improved level of performance and economy as the original EnSolv® products.
Please contact our advisers who are available to discuss your needs and propose the best replacement product.
Or please click here to return to our vapour degreasing products homepage for information about our current products.
EnSolv vapour degreasing solvents distributed by EnviroTech Europe Ltd has been used over the last 30 years by hundreds of companies and for thousands of different applications.
With the unique stabiliser/inhibitor system giving stability and long life for degreasing tanks, reducing maintenance costs and low solvent losses EnSolv is very widely used and approved. Intense worldwide competition needs very tight control of manufacturing costs. EnSolv vapour degreasing solvents gives our users a tried and tested, economical product with the lowest operating costs.
n-Propyl Bromide (nPb) update
For more than 30 years n-Propyl Bromide (nPB) has offered users a safer solvent as a replacement for the carcinogen trichloroethylene as customers using EnSolv will know. Unfortunately, European legislation has set a “sunset date” for the use of nPB, the solvent used as the base material for EnSolv. The inclusion of nPB into Annex XIV has been challenged in the European Court by our supplier, the only manufacturer in the EU. EnviroTech Europe Ltd have always sourced from this consistently high quality manufacturer rather than search out cheaper often lower quality alternatives from Asia.
The Court was very receptive to all the points made. Despite our firm belief that the inclusion of nPB into Annex XIV was not carried out on the basis of all available evidence and we expected a decision earlier, this has been delayed until later in the year. EnviroTech will inform all clients of the outcome as soon as the decision is known.
Just in case EnviroTech are moving forward.
EnviroTech Europe are in the final stages of development of some new and exciting “drop in” cost effective replacements for all our valued customers old and new.
EnSolv CC-A a unique blend of dichloromethane with surfactants for improved cleaning and lifting of surface soils.
ProSolv a new formulation based on 1,2 trans-dichloroethylene with further developments in our laboratories of other blends to complement the range.
If a change is needed these products are available with full technical advice and support to give the same economical, high quality vapour degreasing and service for uninterrupted production. Details are available on our website.
As specialists in cleaning technology our new Aquus CL-One water based general cleaning solution is a game changer for manufacturing industry, petrochemicals, aviation and institutions with one product, safe on all substrates, for removal of oils, grease and odours.
Don’t Panic.
If you are using EnSolv products now, contact our sales team to discuss “nPB sunset data” we have the information you need to help you prepare and to change to the most economical best alternative. Not using EnSolv! get in touch anyway, our expertise is free and it will probably be to your advantage.

Replace Toxic Solvents For Industrial Cleaning
Use Clarea degreasers to replace toxic solvents
for industrial cleaning
Clarea solvent degreasers are a newly formulated range of highly refined hydrocarbon based degreasing solvents with very high cleaning power and low odour, which can be used as an alternative to other hazardous solvents used throughout industry to remove oils, greases, hydraulic fluids cutting fluids and a wide variety of hydrocarbon based protective coatings.
Clarea solvents can be used in dip, brush or in hand-wipe applications.
Clarea HC40 has a relatively fast evaporation rate with low odour and is suited to hand wipe and brush cleaning and air dries while Clarea HC62 is not classified as flammable and is typically used with immersion dip and soak tanks for heavily contaminated parts where oven or forced air drying is acceptable.
Clarea solvents leave minimal residues on drying and are compatible with all metals and many plastics and composite materials. Clarea degreasing solvents can reduce usage and contain no halogens such as chlorine or fluorine so do not deplete the ozone layer or contribute to global warming.
Clarea solvent cleaners are one of the ranges of solvent based cleaners and surface treatment products from cleaning specialists EnviroTech Europe Ltd.
We can provide you with a Material Safety Data Sheets, independent laboratory reports, product samples and technical assistance.
