The AIRERA 18 m³/min compact, all-in-one air-cooled dryer is a premier upgrade engineered for industrial applications demanding both high energy efficiency and space optimization. Equipped with an advanced, upgraded heat exchange system, it features refined flow channels and high-efficiency thermal technology to minimize pressure drop and energy loss, keeping your compressed air system running smoothly at ultra-low energy costs. Its highly integrated, compact air-cooled layout eliminates complex installation piping while saving valuable floor space, reliably delivering a continuous supply of high-quality dry air under diverse operating conditions—making it an exceptional choice for both low-carbon and highly efficient air treatment.
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.

With a high flow rate of 18 m³/min, how does this dryer prevent pressure loss while ensuring excellent drying performance?
We implemented a "wide-channel, low-velocity" structural design in the upgraded heat exchange system. Even under high-capacity flow conditions, the widened internal passages effectively reduce airflow friction, keeping system resistance to an absolute minimum. This allows compressed air to undergo highly efficient heat exchange and moisture condensation with minimal pressure drop, ensuring no compromise on air quality or system power.
From a long-term operational perspective, what practical economic benefits does the "low energy loss" of this AIRERA model bring to a factory?
Pressure drop in a compressed air system directly determines the power consumption of the air compressor. Thanks to the ultra-low pressure drop of our upgraded heat exchanger, the compressor does not need to run at higher set pressures to overcome resistance, directly reducing the motor load. Over long-term operation, this not only saves substantial electricity costs but also minimizes wear on your entire air system, significantly shortening your investment payback period.
Despite its highly compact and space-saving footprint, we have optimized the internal airflow path and equipped the unit with a high-static pressure, high-volume professional cooling fan. Combined with the larger effective heat transfer area of the upgraded heat exchanger, the system achieves rapid, powerful thermal convection—ensuring excellent cooling efficiency and dew point stability even in tight spaces and high-ambient temperature workshops.
