Norgren Hydra-D desiccant air dryers
Norgren has introduced the Hydra-D range of high-purity desiccant air dryers. The dryers use the pressure swing absorption principle to efficiently dry compressed air, minimising the risk of water contamination.
The dryers feature a heatless twin tower configuration, with each column containing a desiccant cartridge incorporating inlet and outlet filtration. This improves the flow distribution, resulting in enhanced performance while lowering the pressure drop, meaning purge air for regeneration is only 15%, while dew-point monitoring means purge only occurs when the bed is fully saturated.
The dryer is controlled by a programmable logic controller system which periodically switches the solenoid valves during operation, reversing the function of each column and ensuring a continuous supply of dry air.
Optimum dew-point performance is ensured through a pressure-maintaining device which controls air velocity. Other features include PLC memory retention, a strong, corrosion-resistant construction, and the ability to be either floor or wall mounted.
