Koganei Membrane Air Dryer KRM
Manufacturer: KOGANEI CORPORATION
Features
This freon-free air dryer uses hollow fiber membranes, providing a gentle touch to the environment without requiring a power supply. As a result, no power supply is needed, enhancing both efficiency and eco-friendliness.
Moreover, the absence of mechanical moving parts eliminates vibrations and heat emissions, contributing to a long service life. The built-in dew point indicator further allows for easy condensation checks, ensuring optimal performance.
Additionally, the extracted moisture is released as water vapor, preventing any issues with drain media. This design also makes the unit compact and lightweight, occupying just 1/5th of the installation space and less than 1/10th of the mass compared to Koganei refrigerating-type air dryers.
