Low presser refrigeration air dryers are used to remove moisture from compressed air systems operating at pressures below 232 psi (16 bar). The following are some common types of low presser refrigeration air dryers:

Cycling refrigerated dryers: These dryers use a refrigeration system to cool the compressed air and condense the moisture, which is then drained out of the system. Cycling dryers turn on and off automatically based on the air demand, which helps to reduce energy consumption.

Non-cycling refrigerated dryers: Non-cycling dryers operate continuously and maintain a consistent temperature within the system. These dryers are ideal for applications with a steady air demand.

Heatless regenerative dryers: These dryers use desiccant material to absorb moisture from the compressed air. When the desiccant becomes saturated, it is regenerated using a portion of the dried compressed air, which is then released into the atmosphere. Heatless regenerative dryers are a reliable and efficient option for low-pressure applications.

Heated regenerative dryers: Heated regenerative dryers use a heater to regenerate the desiccant material, which allows for a faster regeneration process. These dryers are ideal for applications with high moisture loads.

Blower purge dryers: Blower purge dryers use a blower to purge the moisture from the desiccant material, which allows for a more efficient regeneration process. These dryers are typically used in applications with low to medium air flows.
