Desiccant dryers
Why Desiccant?
Refrigeration dryers are excellent for providing lower cost 'dry' compressed air. But they cannot achieve pressure dew points down below 0° C because the water vapour in the compressed air would freeze, blocking pipes and damaging down-stream equipment.
To provide pressure dew points down to -40° C or lower, a desiccant dryer is the most effective solu-tion. The Ingersoll-Rand ThermoSorb dryer uses twin columns filled with desiccant beads to dry the compressed air.
Tiny pores within the desiccant beads trap moisture and remove it permanently from the compressed air
Supply. The temperature of the compressed air is not lowered, so there is no danger of water vapour
Freezing.
The desiccant is supported by a self cleaning stain-less steel wedge shaped support screen. This
Ensures lower differential pressures, constant pres-sure dew points and increases desiccant life.
To maintain acceptable pressure dew point levels, the desiccant must be regenerated by removing the
Water vapour collected within the desiccant. Themost common methods used are either heatless
(TZ) or heated vacuum technology (TZV).
Energy Management System
Regeneration air requirement is dependent on flow, pressure and temperature. Compressed air systems are rarely constant. All three factors change accord-ing to the compressor loading, the ambient temperature and relative humidity. This means that a constant regeneration flow usually wastes compressed air.
The EMS measures the outlet air dew point and adjusts the cycle time accordingly. This can lower
Operating costs dramatically by reducing the regeneration air usage.
The EMS is integrated into the dryer controller, and shows the outlet dew point.
TZV Features and Benefits
