Engineered for highly dusty and high-load mining environments, the AIRERA 65Nm³/min Air-Cooled Refrigerated Dryer represents the pinnacle of our brand’s industrial fluid purification expertise. The unit features a heavy-duty, skid-mounted integrated structure with excellent shock and impact resistance, allowing for true plug-and-play installation and agile field relocation without tedious concrete foundation work. To tackle extreme job site conditions, it is equipped with a high-efficiency industrial compressor and a wide-spaced anti-clogging air-cooled condenser, ensuring stable delivery of low-dew-point compressed air even under continuous heavy-duty operations. Aligned with Google's E-E-A-T principles for high-standard air treatment, AIRERA reliably protects downstream pneumatic rock drills and automated processing equipment from moisture erosion and rust, significantly reducing maintenance downtime while ensuring continuous, safe, and round-the-clock mining production.
Stable performance under high-temperature conditions
This HDR series air dryer can withstand inlet air temperatures of up to 80 degrees Celsius. Even in high-temperature workshops during the summer or in scenarios where waste heat from air compressors is directly fed into the system, it can reliably maintain a dew point between 2 and 10 degrees Celsius, ensuring that dehumidification remains effective even when the inlet air is overheated.

Comprehensive Coverage Across All Flow Rates with Strong Adaptability
With models available for flow rates ranging from 1.2 Nm³/min to 65 Nm³/min, these units can be precisely matched to any application—from low-power air compressors in small repair shops to high-flow units in large factories. Pipe connections ranging from Rc1/4 to DN125 are all provided, eliminating the need for additional adapters or modifications.

Maintains a stable, low dew point to prevent corrosion caused by moisture in the air supply.
A high-quality heat exchange evaporator, paired with an automatic drain valve, thoroughly filters moisture from the compressed air, ensuring that the air used in laser cutting, metal spraying, and electronics manufacturing is free of water droplets—thereby preventing workpiece oxidation and bubbling.

How does AIRERA protect the enclosure and internal piping from flying rocks and severe vibrations on mining sites?
It features a thickened, impact-resistant steel enclosure coated with industrial-grade anti-corrosion paint. Internal piping is vibration-reinforced to absorb shocks from rough relocations and blasting, preventing leaks.
How does this 65Nm³/min dryer avoid frequent tripping under scorching summer temperatures in open-pit mines?
It is configured with a heavy-duty, high-ambient refrigerant compressor and oversized heat exchangers. Paired with smart anti-overload controls, it runs stably in ambient temperatures up to 45°C without overheating shutdowns.
Considering limited technical staff on mining sites, is daily maintenance of this unit convenient?
Extremely convenient. The unit features full-access hinged panels, making all core components and service points fully visible. Operators can quickly wash dust filters or check refrigerant gauges without specialized tools.
