If you operate within the realm of hyperbaric therapy, aquaculture, and the production of ozone and biogas, leveraging on-site oxygen generators proves invaluable for securing top-tier pressurized gas. Opting to generate your oxygen on-site, rather than relying on external suppliers, offers a multitude of advantages.
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.

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.
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.
