Applications for compressed air dryers
Dry compressed air prevents corrosion, condensation, and microbial growth. Adsorption dryers deliver compressed air with a low dew point for processes where hygiene and productivity are critical. The typical target values comply with the " Moisture classes according to ISO 8573 " and ensure reliable operation and high product quality. Adsorption dryers are used in a wide range of industrial applications.
Food & Beverages
Dry compressed air prevents condensation and microbial growth on surfaces that come into contact with products and on packaging lines. Adsorption dryers deliver low dew points, which reduce corrosion in pneumatic systems, improve reliability during filling and sealing, and minimize water carryover. Adjusting the process air to meet the humidity classes specified in ISO 8573 supports hygienic production and consistent product quality.

Frequently Asked Questions About Adsorption Dryers
These FAQs address common technical questions regarding adsorption dryers, dew points, sizing, and standards for compressed air quality in industrial facilities.
What is the difference between adsorption dryers and refrigeration dryers?
Refrigeration dryers cool the air to condense moisture, typically achieving dew points around +3 °C. Adsorption dryers use desiccants to adsorb water vapor and can achieve significantly lower dew points, typically −40 °C to −70 °C (depending on the configuration). Our adsorption dryers achieve dew points as low as −40 °C. This is common in many applications.
Which standards are relevant for determining the dryness of compressed air?
ISO 8573-1 defines purity classes for compressed air, including moisture content above the pressure dew point. Applications within the EU may also require compliance with PED 2014/68/EU, CE marking, and ATEX.
How do I size an adsorption dryer?
Take into account the inlet pressure, the maximum and average flow rate (Nm³/h), the inlet temperature, the target dew point, the ambient conditions, and the duty cycle. Take safety factors for peak loads into account and verify compliance with the ISO 8573 moisture class for the specific application.
