HEAT REGENERATING ADSORPTION DRYER ALM-WDA
Adsorption dryers are used wherever a pressure dew point of +3°C is not sufficient.
The drying of compressed air by adsorption is a purely physical process in which water vapor is bound (adsorbed) to a desiccant by deposition. For adsorption, the moist compressed air is passed through the adsorption dryer. As the compressed air flows through the vessel from bottom to top, the compressed air comes into contact with the hydrophilic desiccant. The desiccant thereby absorbs the moisture and dry compressed air flows out of the vessel.
Description
HEAT REGENERATING ADSORPTION DRYER ALM-WDA
Two vessels connected in parallel are required for the continuous drying process by means of adsorption drying. Each vessel is filled with desiccants which act as a drying medium.
For ALMiG heat regenerating adsorption dryers ALM-WDA high performance desiccants are used, which have a long lifetime at high inlet temperatures and thus provide very low pressure dew points.
The advantage of a vacuum system over other heat regenerating systems is the lower evaporation temperature. Under vacuum conditions, water evaporates at a lower temperature than under pressure conditions. This shortens the heating time, which is cost effective in terms of energy savings.
Advantages:
- The welded steel tanks are designed according to PED 2014/68/EU (other standards and approvals are available upon request).
- A stainless steel slotted screen in the wet end of the vessel is a self-cleaning system that provides uniform distribution of airflow with low pressure differential throughout the system
- Touch screen control for continuous monitoring to communicate with customer’s control equipment via integration of Profibus and Modbus interfaces
- Additional integrated monitoring of inlet and outlet temperatures
- Features load sensing control (LCS) as a standard feature
- Uses standard industrial valves for fast availability and easy maintenance
- Low energy consumption, fast return on investment
- No purge air is required for regeneration /
- “ZERO PURGE”
