We offer a comprehensive and tailor-made filter cleaning service. With our filter cleaning service, we can remove a wide variety of thermo-chemical contaminants and any other unwanted materials from process equipment. We have worked in a host of industrial sectors such as pharmaceutical, oil and gas, utility, chemical, electronics, and food and beverage.
Some examples of filter cleaning contaminants we have removed include:
PPSL is the European leader in thermo-chemical cleaning processes, specialising in the removal of non water-soluble contaminants from a vast array of processing equipment. PPSL is also a leader in filter and hardware cleaning.
We are part of the Precision Group of companies who offer a wide portfolio of filter and hardware cleaning solutions to an extensive client base.

We are industry leaders in component cleaning. With our many years of cleaning experience in filter systems and component cleaning, we offer a tailor-made service, as well as testing processes and technical and environmental support.
Examples of industries that we have provided our filter cleaning services for include pharmaceutical, oil and gas, utility and power, chemical, electronics, and food and beverage.
The process of oxygen cleaning involves removing contaminants from manifolds, valves and pipes. Oxygen cleaning can remove the following contaminants: scale, organic contaminants, inorganic contaminants, grease and oil. We carry out oxygen cleaning on your components to your requirements and to the standards required by industry.
We carry out oxygen cleaning on the following:
PPSL has developed a range of cleaning services for all kinds of industry. We currently provide specialist services in the following sectors and many more!
PPSL utilises a comprehensive range of controlled cleaning process including solvent cleaning, chemical cleaning, ultrasonic cleaning and molten salt cleaning to ensure the highest possible cleaning standards for every part passing through its processing plant.
Solvent cleaning involves the use of especially formulated solvents. This cleaning process is widely used for removing the polymers, paints, rubbers and plastics from metal parts. This very effective process completely dissolves the contaminant without attacking the surface of the metal.
Chemical cleaning can be used uniquely or as part of a multi-stage cleansing process to clean a wide range of filters types and contaminants. The chemicals and chemical strengths used vary according to the contaminant and the material the filter is made from. This ensures the highest quality of cleaning and the least risk to the customers parts.
Molten salt cleaning provides a deep penetration cleaning The parts are placed in a bath of specially formulated salts and heated to the appropriate temperature under carefully controlled conditions. The specific temperature depends upon the contaminant to be removed and the thermal limits of the parts to be cleaned. Because the salt is in liquid form it can penetrate the finest of metal meshes to ensure even non-visible contaminant is removed.
Ultrasonic cleaning uses high-frequency sound waves to agitate and dislodge contaminants from parts. Used in conjunction with the appropriate cleaning chemical produces a very effective and thorough clean. Ultrasonic cleaning is powerful enough to remove tough contaminants, yet gentle enough not to damage the substrate. It provides excellent penetration and cleaning in the hardest to reach places.
The cleaned filter is submersed in alcohol and plugged. Air pressure through the filter is increased gradually and the back pressure is recorded at the point when the first bubble appears through the media. Essentially this test provides an indication of the largest pore size of the filter that can then be compared to the manufacturers specification.
After the 'Bubble Point' is established the back pressure is the recorded at a air flow rate of 10LPM. This gives an indication of the mean pore size of the filter and can be used to assess the integrity and performance the filter will give online.
All filters are weighed after cleaning. This enables us to compare the weight of the cleaned filter with the base weight of the new filter. Over time, weight loss can be tracked, and can be a useful factor when determining the continued integrity of the filter.
All filters are carefully checked, both on receipt and after cleaning, the signs deterioration of the media, physical damage or anything else out of the ordinary. Where damage or imperfections are found that could impair filter performance we will advise the customer. If we believe that the damage can be repaired we will advise on the likely cost of repair and if requested arrange for the repair work to be undertaken.
Over the years we have greatly expanded our range of capabilities and our customer focus. We can now offer tailor-made processes depending on specific customer requirements and work to providing a solution for our customers problems.
We can offer the latest in cleaning technology, filter performance tracking and a comprehensive testing and inspection regime.
We 'add value' for our clients by providing Transport, Logistics and Environmental support. We provide regular feed-back to our customers, identifying possible opportunities to improve their own processes which are identified from our experience and test data. Our expertise in this field has enabled us to extend our client base to include major companies throughout continental Europe and beyond.
We work in partnership with our customers as they develop new processes, and undertake trial cleans on new process plant prior to and during commissioning, through to the implementation of full on-line production. By adopting this systematic approach, we gain a full understanding of our customers' needs which leads to a long-term business relationship which is mutually beneficial.
