Nitroxtec Modular Type Oilless Desiccant Dryers provide oil-free and ultra-dry compressed air with dew points of –40 °C or –70 °C, according to application needs. Designed with an integrated activated carbon and desiccant system, these dual-tower adsorption dryers feature modular, weld-free construction, requiring no welding test and offering low maintenance. Ideal for industries demanding ISO 8573-1:2010 Class 1 oil and Class 2 moisture compliance.

Nitroxtec Modular Type Oilless Desiccant Dryers

Modular, Oil-Free, and Ultra-Dry Air for Demanding Applications

Nitroxtec Modular Type Oilless Desiccant Dryers are engineered for applications that require exceptionally clean, oil- and moisture-free compressed air. Combining desiccant drying with activated carbon filtration, the system effectively removes both water vapor and oil vapors, achieving dew points down to –40 °C or –70 °C and meeting ISO 8573-1:2010 Class 1 for oil and Class 2 for moisture.

The system’s modular, weld-free design eliminates the need for welding certification or testing—making installation easier and maintenance lower. With a dual-tower adsorption system, the dryer ensures uninterrupted operation by alternating between drying and regenerating cycles using 10–15% purge air.

Working Principle

This adsorption dryer uses two towers filled with high-efficiency desiccant (such as activated alumina). As moist compressed air enters the system, it passes through one tower where the desiccant adsorbs moisture. The partially purified air then moves through an activated carbon stage, where it is further cleaned of oil vapor and hydrocarbons, reaching an oil content as low as 0.003 mg/m³.

Meanwhile, a small portion of the dried air (10–15% purge) regenerates the second tower. The system automatically alternates between towers to provide a continuous flow of clean, dry, oil-free compressed air.
