Reliable Drying Results with Component-Kind Ten Minute Cycles
Small DC desiccant dryers also operate in ten-minute cycles to achieve pressure dew points of -40 °C. By reducing the number of switching sequences between the tanks, this method consequently reduces the load on valve components and the SIGMA Dry desiccant. Moreover, long cycle times reduce the amount of compressed air required to restore pressure after the desiccant regeneration phase. For example, 7.6% of the compressed air has to be diverted for a two-minute cycle. However, this proportion drops to 1.3% for a ten-minute cycle with a small DC dryer from KAESER KOMPRESSOREN. This reduction saves energy and extends desiccant service life. The outstanding reliability and efficiency of DC dryers is further aided by the flow optimised round interior of the desiccant tank and by streaming of air through the desiccant via the specially designed screen filters.
