The refrigerant dryer drains moisture into the compressed air by cooling it and liquefying the moisture, respectively. An important parameter is the dew point, which for this type of dehumidifier is + 5C. Another important parameter is the maximum pressure at which the dryer can work. It is recommended that when used in combination with a receiver, place it before it. It works with compressors with different flow rates up to the maximum indicated for the dehumidifier.
