PRODUCT OVERVIEW

Complete refrigeration solution for all configurations

The KYD‑N series is a comprehensive range of refrigerated air dryers designed to deliver reliable moisture removal across a wide variety of system setups. Indeed, the line can accommodate compressors from 1 to 300 HP and flow capacities from 0.7 to 47 Nm³/min, enabling precise sizing according to system requirements. Moreover, each model stands out through its efficient refrigeration control, stable airflow paths, and durable components, all playing a key role in protecting downstream equipment.

 

KyungWon also engineered this series with a compact footprint and easily accessible service points to simplify installation in diverse environments. Thanks to high‑quality materials and consistent dew point control, these dryers are well‑suited for continuous industrial operation, where air purity is essential. In short, the series combines stable performance with strong versatility and easy integration into existing compressed air systems.

Refrigeration control technology

Each model relies on closed‑loop refrigeration technology designed to cool incoming compressed air, condense moisture and automatically discharge accumulated water. The system maintains stable thermal conditions through controlled refrigerant flow and optimized heat‑exchange surfaces, ensuring a consistent dew point. This technology significantly helps to prevent corrosion, protect pneumatic equipment and maintain reliable air quality even under fluctuating load conditions.
