2.2 EST - Energy Saving Technology

Heatless adsorption dryers consume energy through the use of process air called purge air which is used to regenerate the off-line desiccant bed.
In order to provide a consistent outlet dewpoint, any compressed air dryer must be sized to reduce the highest amount of water vapour the dryer
will see (full flow demand in summer conditions). Adsorption dryers typically operate on fixed timing cycles based upon these worst case
conditions, however in periods of low demand and or in winter, when the moisture loading is reduced, the fixed cycle will consume more energy
than is required. In order to significantly reduce this energy loss, each CDAS HL/ OFAS HL dryer is fitted with energy saving technologies as
standard.
Each CDAS HL / OFAS HL includes an electronic control system with colour display, providing a visual indication of the unit's performance.
Linked to this control system is the a dewpoint sensor which constantly monitors the outlet dewpoint and adjusts the regenerating cycle to exactly
match the water vapour loading of the dryer. From the minute the system is operated, it is automatically adapting to ambient and duty conditions,
saving air, energy and money.
