Low Dew Point Twin Tower High Pressure Air Dryer

Low Dew Point Twin Tower High Pressure Air Dryer(KRD-3WXF).

Accurate columns design ensures minimum of 4.8 seconds contact time between inlet air and absorbent substance for the desired dew point.

Extra desiccant is filled to compensate for natural aging; this ensures optimum performance over the expected life span.

The KRD dries the air by operating four solenoid valves to alternate the airflow between two columns. (1) The compressed air flows from the bottom to the top of one of the two columns (A) for a certain period of time and transfers water vapour to the adsorbent substance. At the same time, 14% of the dried air passes through a by-pass, expands to atmospheric pressure and flows from the top to the bottom of the other column (B) removing the moisture that the adsorbent substance had adsorbed during the previous cycle. This phase, known as the regeneration phase, is shorter than the drying phase in order to allow the regenerated column time to return to operating pressure. (2) A new cycle begins, passing the incoming compressed air into column (B) while column (A) is now regenerated.

Future of KRD Series Refrigerated Desiccant Combination Air Dryer
Dry air outlet at low dew point
Extended desiccant service life
Lower maintenance costs
Refrigeration and drying units, filters are all located at one skid for easier access
Advanced auto-mode control system

Less purge air amount is required. Since the compressed air is already dry, purge air amount can be reduced to 3%
