Sierra Why dry compressed air? Contamination reduces efficiency The air we breathe contains contamination in the form of water vapour and airborne particles. During the compression process an air compressor concentrates these contaminants and depending on the design and age will even add to the contamination in the form of oil carry over. Modern air compressors generally have built in aftercoolers that reduce the discharge temperature of the compressed air and with the help of water separators, remove the bulk of liquid water. In some applications this may be sufficient, but the remaining dirt and moisture content suspended in aerosol form, will, if not removed, damage the compressed air system and cause product spoilage. Quality Matters Ingersoll-Rand desiccant air dryers will provide clean compressed air to the highest water classification as prescribed by ISO 8573.1. ISO 8573.1 Quality Classes Class Solid Particle Maximum number of particles per m 3 0.1-0.5micron 0.5-1.0 micron 1.0-5.0 micron Water Oil Pressure (incl. vapour) Dewpoint °C mg/m 3 1 100 1 0 -70 0.01 2 100,000 1,000 10 -40 0.1 3 Not specified 10,000 500 -20 1 4 Not specified Not specified 1,000 3 5 5 Not specified Not specified 20,000 7 Not specified 6 Not specified Not specified Not specified 10 Not specified Installation Guide The result - higher overall cost of operation from: ■ Increased system downtime ■ Reduced production efficiency These problems can be avoided with the correct selection and application of compressed air filters and dryers from Ingersoll-Rand. The Air Solutions Group at Ingersoll-Rand has the widest selection of products and application knowledge to protect your investment and your compressed air system. ISO 8573.1 Class 2.2.1 Dirt, Water and Oil Air quality - With correct selection, the above schematic relates to an installation that would provide Class 2 dirt, Class 2 water, and Class 1 oil. This is recommended to stop downstream corrosion, prevent product spoilage and prolong the life of pneumatic tools and the compressed air system. ■ Filters ■ Refrigeration dryers ■ ■ Condensate management Cooling systems ■ ■ Desiccant dryers Piping systems 2
Desiccant dryers Why Desiccant? Refrigeration dryers are excellent for providing lower cost ‘dry’ compressed air. But they cannot achieve pressure dew points down below 0°C because the water vapour in the compressed air would freeze, blocking pipes and damaging downstream equipment. To provide pressure dew points down to -40°C or lower, a desiccant dryer is the most effective solution. The Ingersoll-Rand ThermoSorb dryer uses twin columns filled with desiccant beads to dry the compressed air. Tiny pores within the desiccant beads trap moisture and remove it permanently from the compressed air supply. The temperature of the compressed air is not lowered, so there is no danger of water vapour freezing. Energy Management System Regeneration air requirement is dependent on flow, pressure and temperature. Compressed air systems are rarely constant. All three factors change according to the compressor loading, the ambient temperature and relative humidity. This means that a constant regeneration flow usually wastes compressed air. The EMS measures the outlet air dew point and adjusts the cycle time accordingly. This can lower operating costs dramatically by reducing the regeneration air usage. The EMS is integrated into the dryer controller, and shows the outlet dew point. Stainless steel wedge wire distribution plate. The desiccant is supported by a self cleaning stainless steel wedge shaped support screen. This ensures lower differential pressures, constant pressure dew points and increases desiccant life. To maintain acceptable pressure dew point levels, the desiccant must be regenerated by removing the water vapour collected within the desiccant. The most common methods used are either heatless (TZ) or heated vacuum technology (TZV). TZV controller 3
