Product Details
28Nm3/min refrigerated air dryer
,fully automatic drainage air dryer
,air-cooled refrigerated dryer with warranty
As an authoritative brand in industrial-grade compressed air purification, AIRERA presents the 28 m³/min smart fully automatic drainage air-cooled refrigerated dryer—a highly reliable, all-in-one air treatment solution designed for large-scale manufacturing facilities. Perfectly aligned with the rigorous demands of continuous heavy-duty production lines, its core integrated condensate monitoring and automatic discharge system precisely senses high-load moisture accumulation to perform seamless, zero-loss drainage, completely eliminating the risk of downstream water carryover caused by manual maintenance oversights. Leveraging AIRERA’s years of expertise in aerodynamic flow control and heavy-duty industrial air-cooling, this unit consistently delivers a stable, ultra-low dew point air supply even under continuous, harsh operating conditions—providing robust protection for your critical production assets.
-
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.

For modern large-scale factories utilizing a 28 m³/min class dryer, how can the fully automatic drainage and operating status of this unit be integrated with central control systems for digital management?
Designed for large-scale industrial applications, this premium AIRERA model is equipped with a smart communication interface compatible with mainstream protocols such as Modbus RTU. From the central control room, operators can monitor real-time operating temperatures, dew points, and even track the discharge frequency and level status of the auto-drain valve. If any minor drainage anomaly occurs, the system immediately transmits an early-warning signal to the central platform before any risk escalates—providing a solid data foundation for predictive maintenance and digital workshop management.
During seasonal transitions with extreme temperature fluctuations, the volume of condensate varies drastically. How does the auto-drainage system of the AIRERA 28 m³/min dryer adapt to these changes to ensure stable air quality in extreme conditions?
AIRERA’s self-adaptive drainage algorithm has been optimized based on extensive field data from diverse industrial operations. During hot and humid summer seasons when condensate spikes, the system automatically increases discharge frequency and duration to prevent moisture accumulation. Conversely, in dry and cold winter months, it adjusts settings to reduce mechanical wear and prevent external drain line freezing caused by over-frequent cycling. This dynamic adjustment ensures high stability and reliability throughout seasonal transitions year-round.
How are the design and performance calibration of this 28 m³/min air-cooled refrigerated dryer aligned to meet international ISO compressed air quality standards?
AIRERA strictly follows the ISO 8573.1 international compressed air quality standard for product development and performance calibration. By employing thermodynamic simulations and rigorous boundary-limit testing, the outlet air moisture level fully complies with the strict water vapor classes defined under ISO 8573-1. We deliver clean, certified air for industries such as precision electronics and heavy machinery, helping our clients easily pass stringent industry audits and quality inspections.
