As a global solutions provider for a very wide and diverse range of industries and applications, the many business activities of domnick hunter are divided into two main business segments, Industrial Operations and Process Operations. Parker domnick hunter – Industrial Operations Industrial Operations is a World leader in the filtration, purification and separation of compressed air and gases with many significant brand labelled products and major customers. Specialising in the fine end of the market where product quality, support and technological excellence are paramount, it designs and manufactures filters, dryers, breathing air purifiers, condensate management and ancillary equipment. domnick hunter is instrumental in the development of both the international standards for compressed air and filter testing, and continues to work closely on new standards with such governing bodies as the British Compressed Air Society (BCAS), the International Standards Organisation (ISO), PNEUROP, and the Compressed Air and Gas Institute (CAGI). Compressed Air Purification domnick hunter high efficiency OIL-X EVOLUTION filters provide the complete solution for the removal of solid contamination, liquid oil and water droplets, oil odours and vapours to levels so low that only the most advanced equipment can detect any remaining contaminants. Typically, domnick hunter filters can remove contaminant particles down to one hundredth of one millionth of a metre (0.01 micron) in size - 4,000 times smaller than the smallest particle visible to the naked eye!. OIL-X EVOLUTION filters are the most energy efficient compressed air filters in the World, and industries rely on this level of technology for trouble free, efficient production. Whilst filters can remove solid and liquid contamination, they cannot remove water vapour which must be removed with a compressed air dryer. It is not usually cost effective or necessary to dry all the plant air to the highest standard and it is normal practice to dry the ring main air with a refrigeration dryer, and only dry the air for the critical point of use applications with a desiccant dryer. domnick hunter pioneered and patented the first ranges of PNEUDRI modular desiccant dryers which are still today’s benchmark, thousands being in service World-wide. Some critical applications require a pressure dewpoint of minus 70°C pdp, however, most customers opt for minus 40ºC pdp, because below minus 26°C pdp, bacterial growth is inhibited and therefore cannot contaminate processes or spoil end products. Safe Breathing Air Respiratory protection from air borne contamination is essential for the health and comfort of workers. Simple respirators are limited in their application but compressed air purified to breathing air standards can be used to protect against any form of contamination. domnick hunter also offers a full range of breathing air purifiers for single or multi-person use in applications such as shot blasting, spray painting or for safety in hazardous environments. To support the above, domnick hunter also produces an air purity test kit to enable the testing of contaminants upstream and downstream of installed breathing air purifiers. All domnick hunter breathing air purifiers comply with or exceed the latest international breathing air standards. On-site Gas Generation domnick hunter also provides much innovative development for on-site nitrogen, air and hydrogen gas generation equipment for industrial and scientific applications. In the advancement of a more flexible gas supply, high-purity gases coupled with improved performance and safety, are primary benefits from the comprehensive ranges of gas generators. The domnick hunter MAXIGAS and scientific ranges of nitrogen gas generators allows users to produce ultra high purity nitrogen gas from a supply of compressed air, without the need for high pressure cylinders or liquefied gas supplies. Parker domnick hunter – Process Operations Process Operations specialise in the manufacture and supply of filters for the clarification, stabilisation and sterilisation of liquids and gases, principally in the pharmaceutical, beverage, food and electronics industries, and also in laboratories. Throughout these hi-tech and other process industries, there are numerous applications where clean compressed air is just not good enough, they need sterile air. To achieve this, domnick hunter offers ranges of both microfibre and membrane filters in special stainless steel hardware which allows systems to be steam sterilised and the filters to produce a constant stream of bacteria free sterile air. Pure Liquids Although people never give it a thought, many of the day-to-day products they consume or use need to be filtered to remove contaminants before they
