Nitroxtec High Pressure Oilless Desiccant Dryers
Ultra-Clean Air, Even at 300 Bar
Nitroxtec High Pressure Oilless Desiccant Dryers are engineered for high-pressure air systems, offering reliable performance at operating pressures from 40 to 300 bar. Designed for industries where air purity and pressure integrity are critical, these dryers remove both moisture and oil vapors using a dual-stage process: high-efficiency desiccant adsorption followed by activated carbon filtration.
Achieving dew points as low as –40 °C and oil content down to 0.003 mg/m³, they meet strict ISO 8573-1:2010 Class 1 for oil and Class 2 for water standards. Built with high-pressure-rated vessels and components, the system is ideal for PET bottle production, aerospace applications, laser cutting at 40–300 bar, and defense industries.

Working Principle
Compressed air enters the system and flows through a desiccant-filled vessel where moisture is adsorbed. The air then passes through an activated carbon stage, which eliminates residual oil vapors to ensure ultra-clean output. While one tower is in drying mode, the second regenerates using 10–15% purge air. This alternating cycle allows for uninterrupted, 24/7 operation, even at high pressures. The system is managed by a PLC-based control panel that monitors dew point, regeneration timing, and system performance.
