Our compressed air systems utilize the latest technology to provide energy efficient solutions with low life-cycle costs. Air purity is attained by meeting strict international standards that can only be achieved with filtration, water separation and drying. The use of clean dry compressed air ensures high levels of reliability, and guarantees that quality standards are met and production costs are reduced.
Refrigerant dryers are the most common type of drier technology used in many industries. As the name suggests, heat exchangers are used to cool compressed air which condenses the bulk amount of water vapor within the air. Once the compressed air is cooled and water is removed, the air is reheated to approximately room temperature to ensure no more vapor forms within the pipe system.
Principle Of OperationThanks to the highly efficient design, the refrigerant circuit absorbs lower power and uses less refrigerant charges than other comparable dryers. Developed around a state-of-the-art aluminum heat exchanger featuring an air-to-air section, an air-to-refrigerant section, a highly efficient stainless steel demister separator and a moisture collection chamber, the new range provides air quality at unrivaled costs.
Adsorption compressed air dryers are designed to remove moisture by passing air over a regenerative desiccant material, which attracts and retains water vapour molecule.
The term pressure dew point refers to the temperature at which water condensation occurs. A typical pressure dew point specified for an adsorption dryer is -40°C which prevents corrosion and inhibits the growth of microorganisms.
The compressed air to be treated is filtered both at the inlet and at the outlet of the adsorption dryer, serving to protect the adsorbent material from contaminants as well as to retain particles of the adsorbent material at the outlet. Entering to the adsorption dryer, compressed air is made to circulate in one of the two towers of which the dryer is made up.
Inside, when it comes into contact with the desiccant material, it releases nearly all the water vapor it contains into this material by the physical phenomenon known as "adsorption". The residual vapor remaining in the compressed process fluid after the drying process is assessed indirectly according to its dew point, i.e. the lowest temperature to which the process fluid can be cooled without the remaining vapor condensing (at working pressure or atmospheric pressure as required).
While the most common types of air dryers are either adsorption or refrigerant dryers; adsorption dryers are predominantly used for instrument air in EPC contracts.
Hybrid compressed air dryers are designed by combining refrigerant and adsorption dryer technology. This unique combination offers higher quality air and lower energy consumption compared to traditional heatless and heat regenerative adsorption dryer technology.
A compressed air dryer is used for removing water vapor from compressed air.
The process of air compression concentrates atmospheric contaminants, including water vapor. This raises the dewpoint of the compressed air relative to free atmospheric air and leads to condensation within pipes as the compressed air cools downstream of the compressor, so compressed air including water vapor shall be removed through air dryer.
Almost every air system uses an after cooler (air cooled or water cooled) to cool compressed air as it exits the air compressor. The after cooler will cool the air. In almost all cases, the air exiting the after cooler is saturated, meaning it cannot hold any additional water vapor at its present temperature and pressure.
The instrument air dryer packages are supplied as custom to meet the client’s requirements. The instrument air dryer packages are equipped with its instruments, junction boxes, and the PLC based controller. Ingersoll Rand provides standard designs or totally engineered for heavy-duty and severe ambient installations, extreme temperatures or explosive environment conditions. The dryer packages can be packaged in a skid or containerized.
Safe operation - Untreated air can cause corrosion and damage to pipeworks and the internal structure of your air compressor. Air dryers are used to dehumidify compressed (process) air to significantly lessen or eliminate water vapor present in the air stream, or to eliminate contaminated air. Industrial air dryers can be used to reduce the dew point of compressed air to below the lowest temperature obtained at site.
Reliable operation - Compressed air dryer packages will help to keep your air system running damage-free and your operation safe and reliable. Choosing an equipment with high quality components ensures a continuous supply of clean, dry air and reliable operation.
High-quality end-product - Air containing water vapor can cause product deterioration, which can be very costly for businesses. The compressed air dryer ensures that the air is pure and dry before it reaches the point of use, thus ensuring optimum quality of the final product.
