Ash Air - Compressed Air Dryers - Refrigerated, Desiccant

Discover compressed air dryers and protect your air compressor set up

If you have experience using an air compressor, you may have observed the presence of moisture in the air. This is due to the fact that water cannot be compressed like air can. When air is compressed, the moisture content per unit volume increases, leading to condensation. It is essential to use compressed air dryers to eliminate this moisture, as it can result in corrosion, quality problems, and the growth of microorganisms in your air system.

What is a compressed air dryer?

Dryers are essential for removing extra moisture from compressed air, ensuring industry compliance and safeguarding your air compressor system. Consider refrigerant (fridge), adsorption, and membrane dryers, each offering unique advantages to help you manage costs and maintain air quality standards. Choose the right type to meet your specific needs and requirements.

Desiccant Air Dryers

Our innovative desiccant dryers give customers efficient protection against the presence of any humidity in the air, which often is the source of pipe corrosion and decreased efficiency of equipment and tools.

The Ash Air range of advanced technology 360-1080 m3/hr and 1188-10800 m3/hr adsorption air dryers are for customers who have a focus on energy efficiency and low operating costs, while maintaining the highest standards in air purity. Our Pneumatech blower purge air dryers use heated blower purge air to remove moisture from the desiccant material, which means no purge loss during regeneration.

Different types of compressed air dryers:

Refrigerant dryers, commonly used in various applications, are designed to maintain a PDP of +3 °C/37.4 °F. They feature both air-to-air and air-to-refrigerant heat exchangers and can be either air-cooled or water-cooled. Pneumatech provides a range of options including non-cycling, cycling, and VSD refrigerant dryers to meet specific efficiency and investment needs.

Adsorption or desiccant dryers utilize a hygroscopic substance such as silica gel to remove moisture from compressed air. The air passes through the material, effectively drying it. These dryers can achieve a Pressure Dew Point (PDP) ranging from -10 °C/14 °F to -70 °C/-94 °F. In order to maintain consistent performance, adsorption dryers are equipped with two drying vessels. One vessel is used for drying the incoming compressed air, while the other is used for regenerating the desiccant material. Our dryers employ three different methods for regeneration: purge regeneration (also known as "heatless-type dryers"), heated purge, and blower regeneration.

Membrane dryers utilize a technique known as "selective permeation." They are made up of a cylinder that contains numerous small hollow polymer fibers coated on the inside. By selectively allowing certain molecules to pass through, these fibers eliminate water vapor, reaching typical PDP levels of +3 °C/37.4 °F.

Importance of air dryers in NZ

Compressed air dryers are crucial for maintaining the reliability and integrity of your air system, as well as meeting the ISO 8573-1 standards. These regulations determine the permissible levels of contaminants, such as water, in treated air. The standard outlines various air quality classes, each with specific requirements for Pressure Dew Point (PDP) levels. For instance, Class 1 under ISO 8573-1 necessitates a PDP of -70 °C/-94 °F, while Class 4 indicates a PDP of +3 °C/37.4 °F.

The use of compressed air dryers in New Zealand is required in countless industrial and professional applications

Textile industry

The modernization of production processes has led to an increased demand for compressed air in textile manufacturing. This versatile "fourth" utility is crucial for the operation of various machines involved in different production processes, including:

Air-jet weaving
Man-made fiber production
Texturizing
Winding and dyeing non-woven textiles
Pneumatic transport for PET chips

Additionally, compressed air is essential for powering spinning machines, grinding mills, and other equipment used in denim processing, yarn production, and various other manufacturing processes. Furthermore, compressed air plays a vital role in treating the substantial volume of wastewater generated by textile production.

Pharmaceutical industry

The pharmaceutical industry stands as one of the most rigorously regulated sectors, and for valid reasons. The products crafted within pharmaceutical facilities have the potential to alleviate suffering and preserve lives. To accomplish this, the production process must adhere to rigorous quality standards, starting with the crucial element of exceptionally clean compressed air. Pneumatech provides a comprehensive array of solutions designed to help pharmaceutical companies meet the exacting compressed air quality standards required in their operations.

Food and beverage

Food and beverages hold paramount importance in our lives, serving as essential sustenance. In the same way our bodies rely on them for sustenance, producers of these items depend on high-quality compressed air. This dependency arises from the need to guarantee the safety and palatability of the consumables. The food industry is subject to strict compressed air standards, and Pneumatech provides appropriate air dryers and filters to ensure the quality of food products.

Cement production

Similar to compressed air, cement is ubiquitous in our surroundings, and the absence of either would render our modern world inconceivable. It follows logically that compressed air plays a vital role in the cement manufacturing process. However, it is crucial to adhere to quality standards for compressed air in cement production, as untreated compressed air has the potential to jeopardize the final product. Pneumatech provides air dryers and filters essential for maintaining a seamless and dependable cement production process.
