Compact and Large Desiccant Dryers
Series DC 12 to 1545
Flow capacity 1.2 to 154.5 m³/min
Assuming perfect operation under reference conditions (purge air requirement 13.5 %),
PDP -40 °C, ten-minute cycle time (5 min adsorption, 4 min desorption, 1 min pressure build-up),
running time 8000 operating hours/yr.,
compressed air generating costs 2 Euro cent/per m³, current DC list price.
Reliable and Efficient Pressure Dew Point Performance to -70 °C
Low-pressure dew point performance can also be achieved & sustained with continuous system operation, even at full load and with high inlet temperatures. With a purge air requirement of only 13.5 % (determined over one cycle under reference conditions), these highly efficient dryers more than pay for themselves within a very short time and enable considerable savings, especially in comparison with conventional systems (see graph). High performance is achieved using large dryer tanks filled with generous volumes of KAESER’s quality SIGMA Dry desiccant to ensure sufficient drying capacity even under extreme load conditions. Stainless-steel diffusers provide optimal airflow over the desiccant to ensure an even drying load. Purge air requirement is further reduced, as the heat gathered during adsorption is temporarily stored in the desiccant and can be used for regeneration. The drying process is carried out in long energy-saving cycles that are kind to components due to the minimal number of switching and pressure build-up phases.
| ||Desiccant Tank|
Application specific design for a million load cycles in accordance with AD2000.
All requirements met as per Pressure Equipment Regulation 97/23/EG.
Continuous operation of at least ten years is possible.
| ||Maximum Reliability|
High quality changeover switches ensure minimal pressure drop and gentle pressure build-up to reduce pressure fluctuations in the air network. Pressure is also monitored during the individual cycle phases. The volume of required purge air is precisely adjusted to meet demand via valve and pressure gauge, whilst operational status can be viewed at a glance via a moisture indicator.
| ||Service-Friendly Design|
The radial layout of the desiccant tank’s inlets and outlets enables the desiccant to be easily changed using large connectors on the highest or lowest point of the tank. Furthermore, the connectors are easily accessible for tank inspections and the filter housings are also within easy reach. These features, combined with soundproofing that's simple to remove and clean, contribute to significantly reduced servicing and maintenance costs.
| ||Low Noise|
With at least two powerful silencers (according to model size), even standard DC series dryer models operate extremely quietly. Special soundproofing is also available for certain models to provide additional noise reduction. For example, depending on the dryer, the optional soundproofing can reduce operating noise levels to 80 dB(A).
