Halward - is in the field of Compressed air Drying and Air Treatment for more than a decade. We offer Air Drying technologies to suit the varied applictions in the industry. The various air drying technologies we recommend are
1. Point of Use Air Dryer - A combination of Physical moisture separation and Chemical Adsorbtion.
2. Refregeration type Air Dryer.
3. Heatless / Desiccant Type Air Dryer.

Depending on the application of the Compressed Air we can suggest the type of Air Dryer most suitable for your requirement so as to minimize the operational costs.

In the compressed air system, hard particles assault equipment and piping. The result is damage to the system and more particles generated. Examples of particles found in a compressed air system include scale, metal oxides, and dirt. Particles in a compressed air system can:

• Plug orifices of sensitive pneumatic instrumentation
• Wear out seals
• Erode system components
• Decrease air tool efficiency
• Damage finished products

Apart from particulate matter, Compressed air is alos saturated with water and different gasses. Chemical gases, either alone or in combination with other contaminants, may cause additional damage or create a potential hazard to the process or personnel. Chemical gases found in compressed air systems include:

• Freon
• Chlorine
• Sulphur
• Carbon dioxide
• Hydrocarbons
• Carbon monoxide

Filtering and drying processes remove particles, moisture, microbes, and chemicals from compressed air. Clean, dry air protects the air system, reduces maintenance costs and increases finished product yields.

Halward Has a range of Filters:

• Removes particles from compressed air and gases
• Protects downstream equipment from solid particles
• Available micron ratings from .3 um – 50 um
• TFE, polyester, fiberglass & organic fiber media
• Piston seal technology ensures effective sealing of element to housing
• In-house vessel fabrication facility carries an ASME Code stamp & PED (97/23/EC)
• Housings designs from 14.7 PSIA – 1440 PSIG
• Materials of construction include carbon and stainless steel
• Housings are available with connection sizes ranging from 1⁄2 inch to 12”

Typical Applications include filteration in

• Natural Gas
• Compressed Air
• Industrial Gases
• Guard Filters
• Point of use

Air Quality Testing

Compressed air is used in a wide variety of manufacturing and commercial applications, and in some industries the quality of the air is extremely important.

Compressed air typically has three main contaminants which are water, particles and oil.

Contaminants originate from three general sources:

1. Contaminants in the surrounding area of the compressor are drawn into the air system through the intake of the air compressor. Ingested contaminants appear in the form of water vapor, hydrocarbon vapours, natural particles and airborne particulates.

2. As result of the mechanical compression process, additional impurities may be introduced into the air system. Generated contaminants include compressor lubricant, wear particles and vaporized lubricant.

3. A compressed air system will contain in-built contamination. Piping distribution and air storage tanks, more prevalent in older systems, will have contaminant in the form of rust, pipe scale, mineral deposits and bacteria.

If the compressed air system has not been designed for your industry specific requirements, it has potential to cause major problems to product quality and operating expenses.

This is especially important for industries such as food and beverage and pharmaceutical if the air comes into direct contact with the product or indirect contact with the packaging.

In order to be compliant with industry standards, the quality of your compressed air should be considered as part of the hazard analysis and critical control point (HACCP) activity.

At Halward, we offer advice about your current compressed air system and provide quality solutions to ensure you achieve the air quality your business requires.

Before we do anything, we ask the question: ‘what air quality do you require?’ We ensure our analysis and recommendations align 100% with industry standards, including taking into account environmental factors in accordance with your system design.
