High purity nitrogen, hydrogen and air are used for a wide range of critical life science and chemical analysis industries and applications. However, obtaining a continuous supply of the high purity gases can be problematic and expensive.
Parker offers an ideal solution for this requirement with cost effective and comprehensive ranges of gas generation systems, both point of use and centralised systems that enable users to produce their total demand for analytical gases, on their premises, under their complete control.
Nitrogen gas is used for a wide range of industrial applications, from modified atmosphere packaging for perishable food products to preventing fire and explosion in chemical plants. However, while nitrogen is all around us, making up 78% of the air we breathe, obtaining a ready supply of the gas can be problematic and expensive.
Parker domnick hunter offers an ideal solution to this requirement with a comprehensive range of cost effective nitrogen gas generation systems, that enable users to produce their total demand for nitrogen gas, on their premises, under their complete control.
Parker domnick hunter offer a range of high efficiency coalescing compressed air filters for the removal of water and oil aerosols, solid particulates and micro-organisms, and dust filters for the removal of dry particulate and micro-organisms from industrial compressed air systems.
Failure to remove or reduce contamination will cause a number of problems within the compressed air system. This can include corrosion within compressed air storage vessels and the air distribution system, as well as blockage or damage to production equipment; which can result in product contamination and unhealthy working conditions.
All Parker domnick hunter high efficiency compressed air filters deliver air quality in accordance with all editions of ISO 8573-1 which has been independently verified by Lloyds Register. OIL-X EVOLUTION filters offer minimum pressure loss. Starting with a low pressure loss and staying low enables the user to save energy and money, giving the filter a low lifetime cost in comparison to alternative compressed air filters.
Filter housings are guaranteed for 10 years and coalescing and dust removal elements are covered by a Parker domnick hunter one year compressed air quality guarantee, rene
Parker domnick hunter offer a range of high efficiency heatless and heat regenerative compressed air dryers for the removal of water vapour from a compressed air supply. If the water is not removed, it will cause corrosion of the distribution system, blocked or frozen valves and machinery, as well as providing an ideal breeding ground for micro-organisms. Adsorption compressed air dryers remove moisture by passing air over a regenerative desiccant material, which attracts and retains the water vapour molecules. The term pressure dewpoint refers to the temperature at which water condensation will occur, a typical pressure dewpoint specified for an adsorption dryer is -40°C which prevents corrosion and inhibits the growth of micro-organisms. A pressure dewpoint of -70°C is often specified for critical applications.
Compared to traditional twin tower dryer designs, Parker domnick hunter compressed air dryer’s unique modular construction is typically 60% the size and weight of conventional twin tower desiccant dryers. Providing a simple to install and easy to maintain dryer which is fully corrosion protected and supported by numerous international standard approvals. The unique design of the Parker domnick hunter PNEUDRI dryer range means periodic pressure vessel inspections are not required.
Carbon dioxide is used within beverage production for carbonation of the finished product and for inert storage of flavorings.Quality Guidelines for producers of beverage CO2 are issued by organizations such as the International Society of Beverage Technologists (ISBT) in the US and the European Industrial Gases Association (EIGA). However, potential CO2 impurities may still occur as a result of trace contaminants being carried over in the source gas or by being introduced into the bulk liquid CO2 during storage and transportation.
In response to increased awareness to the impact on beverage characteristics that potential impurities can have, Parker domnick hunter has developed a range of PCO2 carbon dioxide gas polishers, designed to act as quality incident protection units to help in protecting the final beverage against possible flavor defects and hazards. Potential CO2 impurities known to have flavor impact on beverages include volatile organic compounds (VOCs), aromatic hydrocarbons, acetaldehyde and sulphur compounds. Parker domnick hunter's unique PCO2 systems for retail point of use and plant scale operations are recognized as the industry's preferred choice for CO2 polishing systems and are used in over 80 countries worldwide.
After the oily condensate has been efficiently removed from the compressed air system it cannot be discharged directly to the foul sewer without first having the oil content reduced to within legal disposal limits. Parker domnick hunter ES2000 Series Oil / Water Separators are a simple, economical and environmental solution.
ES2000 Series Oil / water separators are installed as part of the compressed air system and simply reduce the oil concentration in the collected condensate to a level permitted, for discharge. This allows the larger volume of clean water, up to 99.9% of the total condensate, to be discharged safely into the foul sewer and the relatively small amount of concentrated oil to be disposed of legitimately and economically
Parker domnick hunter offers four different ranges of desiccant compressed air dryers; which are specially designed for the rail industry. Their function is to remove water vapour from the air supply generated by the on-board compressor. Each uses patented design technologies that have the ability to withstand the rigours of shock and vibration in the most demanding and extremes of operating conditions and climates.
Parker domnick hunter railway air dryers can be installed for use on various rolling stock vehicles including, light rail vehicles, trams and high speed passenger trains, as well as heavy rail locomotives and freight vehicles. With the protection of pre- and after compressed air filters clean, dry oil-free compressed air can be delivered in accordance with NF F11-100 and ISO 8573-1:2010 air quality standards. Pneumatic applications include on-board functions such as the trains breaking system, self-levelling air suspension, pantograph operation, automatic doors and other ancillary applications (e.g. wipers and horns)
These ranges of railway compressed air dryers offer unique design features allowing horizontal, vertical or stacked mounting orientations, which can be sized to fit into any envelope concern to meet the trains’ space requirements.
Whether new build or refurbishment of locomotives and rolling stock, total compressed air protection can be provided by the installation of a dedicated Parker domnick hunter railway dryer package complete with pre - and after filters.
The Railway TF compressed air filter range manufactured by Parker domnick hunter has been designed for the efficient removal of bulk liquids, aerosols and particulate from the onboard rolling stock compressed air systems helping to reduce unplanned maintenance and set out for service costs.
Compressed air is used to control various on-board pneumatic applications including the trains breaking system, pantograph operation and self-levelling air suspension. A clean, dry oil-free supply is essential to keep the rolling stock operational. When installed with Parker domnick hunter Railway compressed air dryer, compressed air can be delivered in accordance with NF F11-100 and ISO 8573-1:2010 air quality standards.
All Parker domnick hunter compressed air filters are corrosion protected using alocrom on all aluminium surfaces with external surfaces being further protected with a dry powder epoxy paint coating. When supported by a planned maintenance schedule Parker domnick hunter guarantees the filter housing for a 10-year period.
Compressed air is a safe and reliable power source that is widely used throughout industry. Approximately 90% of all companies use compressed air in some aspect of their operations, but unlike gas, water and electricity, compressed air is generated on-site, giving the user responsibility for air quality and operational costs.
However, untreated compressed air will cause major performance and reliabilty problems with any system. Almost all of these can be directly attributed to contamination. After generation, compressed air typically contains up to 10 different contaminants as it enters the distribution system. Modern production facilities are increasingly becoming more complex and ascompressed air applications become more critical, compressed air purification is essential
