Domnick Hunter Introduces Mini Dry Air System

PNEUDRI MiDAS, a mini dry air system, provides plant engineers uninterrupted clean dry compressed air just where they need it without the need for drying the entire compressed air system which can be both costly and totally unnecessary.

NEUDRI MiDAS contains both a high efficiency and particulate filter along with a desiccant cartridge inside a single module allowing contaminated compressed air in and clean dry air out. A 100% service can be achieved in less than 15 minutes due to the quick release top cap arrangement, which does NOT require the inlet/outlet ports to be disconnected as with traditional systems.

Boasting top end re-pressurization, PNEUDRI MiDAS ensures uninterrupted compressed air at all times. The unit can be placed directly after a compressor OR after a particular application where the air is critical to the operating process or end product. Units can be wall or canopy mounted using an optional mounting kit where space is limited. The unit is available at a pressure dewpoint of -40°F or -100°F and at flow rates of 3 to 20 scfm at 100 psig.

Typical applications include: Computer Numerical Control (CNC) Machines, Coordinate Measuring Machines, Laboratories, Lasers, Packaging Machines, Instrumentation, Processing Equipment and Conveying Machines.

Portable Screw Compressors C 85-14 – C 140-9 In this widely successful range, Compair relies on the new QSB 4.5 engine range from Cummins. These engines are fitted with electronic injection and meet all the EU demands with regards to exhaust emissions for the foreseeable future.

At the customer’s request, Compair will continue to supply the standard machine with the proven mechanically regulated engine for export markets outside Europe.

Design for the toughest construction site conditions This new series of compressors offers the highest reliability, performance and quality of compressed air, whether it is for road building or civil engineering applications, cable blowing, concrete spraying, spray painting, piling/pile capping or DTH drills. This range comprises seven new single axle models. The series C85-14 – C140-9 is particularly suitable for sand blasting work on concrete or steel, for building demolition and special construction work such as piling and geotechnical drilling. Specialised building contractors in these areas today demand accurately defined air quality for both oil and water content. Options such as aftercoolers and air line lubricators guarantee this desired air quality.

The C8514 – C140-91 range provides 8.5-14m3 of air at operating pressures of between 8.6-14 bar. The compressor is equipped with numerous standard options, which, from any other manufacturer, would only be available at a great additional cost to the customer. Thanks to the inclusion of two batteries the best running performance can be guaranteed even in the coldest of winters. The long life cycle of these compressors are further enhanced by automatic shutdowns.

TurboScrew Compressors with new Cummins engines Introduced six years ago, the TurboScrew series, with its unique technology for energy efficiency and reliability, is being enhanced. The new QSB 6.7 engine developed by Compair in conjunction with Cummins, has made this possible. The bi-turbo technology of Compair’s TurboScrew portable system makes it the best in its class in terms of reduced fuel consumption for applications e.g. ship refurbishment, oil-barrier, building and bridge refurbishment, dry-ice-blasting, drilling, pneumatic lance, earth loosening, ground exploration, water well drilling.

This is achieved through the use of a second exhaust turbo charger which precompresses the inlet air for the screw compressor stage. The patented machine concept significantly improves the efficiency of the compressor, particularly over everyday partial load operation. This design produces savings of up to 30% on diesel fuel at the same volume flow rate as other similar output machines. This unique technology provides machines which are the lightest in their class, up to 2000 kg lighter than other comparable compressors of any supplier.

At the customer’s request, Compair will continue to supply the standard machine with the proven mechanically regulated engine for export markets outside Europe.

Low operating weights CompAir also scores highly when it comes to the operating weight of the machines. In the 3.5 to 5.0 m³/min compressor class, CompAir offers machines weighing less than 750 kg, which eliminates the need for restrictions placed on road transportation and driving licence classes in many European countries. This also applies to the 2.0 to 2.5 m³/min class in a similar manner.

DOMNICK HUNTER COMPRESSED AIR DRYERS

Drying Water Vapor

Water vapor is water in gaseous form and will pass through water separators and coalescing filters just as easy as the compressed air. The ability of air to hold water vapor is dependent upon its pressure and its temperature. The higher the temperature, the more water vapor that can be held by the air, the higher the pressure, the greater amount of water vapor is squeezed out. As large volumes of air are drawn into the compressor and compressed, the temperature of the air increases significantly. This allows the heated air to easily retain the water vapor in the atmospheric air. Unlike water in a liquid or aerosol form which is removed from compressed air using a coalescing filter; water vapor (water in a gaseous form) can only be removed using a dryer.

Types of Compressed Air Dryers

Desiccant Air Dryers

Desiccant dryers remove water vapor by passing air over a regenerative adsorbent material known as desiccant which strips the moisture from the air. All desiccant air dryers remove water vapor using this method, however the adsorbent must be periodically regenerated to ensure a continuous supply of dry air, and a number of different regeneration methods are available.

Pressure dewpoint is the term used to describe the temperature at which condensation will occur and the water removal efficiency of a dryer is expressed as a pressure dewpoint (written as a temperature). Desiccant dryers are extremely efficient and typically provide pressure dewpoints of -40°F (-40°C) or -100°F (-70°C). This means for water vapor to condense into a liquid, the air temperature would need to drop below -40°F (-40°C) or -100°F (-70°C) respectively. The actual air temperature after a desiccant dryer is not the same as its dewpoint.

Typically, a pressure dewpoint of -40°F (-40°C) is used in most applications as compressed air with a dewpoint below -14.8°F (-26°C) will not only prevent corrosion, it will also inhibit the growth of micro-organisms within the compressed air system. Desiccant air dryers (also known as regenerative air dryers) can be purchased in a tower tower dryer or modular dryer construction. Types include: heatless dryer, heated dryer, blower purge dryer and a high pressure air dryer. Point of use dryer and inline air dryer varieties bring clean dry air just where you need it at the point of use application.

Refrigerated Air Dryers

In general purpose applications, refrigerated air dryers are often used in place of desiccant air dryers. Refrigerated air dryers remove water vapor by cooling the compressed air and collecting the condensed liquid. For this reason, they are limited to to positive pressure dewpoints to prevent freezing of the condensed liquid providing pressure dewpoints of +37.4°F (+3°C), +44.6°F (+7°C) or +50°F (+10°C). This type of dryer will remove free water from the system and slow corrosion, however they will not inhibit bacterial growth and are not suitable for installations where piping is installed in ambient temperatures below the dryer dewpoint (i.e. systems with external air receivers and piping). Types include but are not limited to: thermal mass dryer and high temperature refrigeration.

Are all compressed air dryers the same?

Compressed air purification equipment must deliver uncompromising performance and reliability while providing the right balance of air quality with the lowest cost of operation. Many manufacturers offer products for the filtration and purification of contaminated compressed air, which are often selected only upon their initial purchase cost, with little or no regard for the air quality they provide, the cost of operation throughout their life or indeed their environmental impact. When purchasing purification equipment, delivered airquality, the overall cost of ownership and the equipment’s environmental impact must always be considered.

Getting the most out of a compressor depends largely on air quality.

Compressed air always has been a major source of energy for work in construction and industrial applications. Both oil-flooded and oil-free compressors provide the right solutions to the many rental applications requiring compressed air. The pressure and volume of air required are key factors in choosing a portable compressor for the application. For many contractors the "quality" of the air provided is also an important consideration. "Quality of air" can be defined by how dry, clean and free from contaminates the air is.
