Description
Efficient and economical compressed air drying – resulting from many features of the DPS series
Series DPS 10-100 adsorption dryers, optionally available as DPS 10-100 A with additional activated carbon oil vapour adsorber, can dry the compressed air to a pressure dew-point of -25°C, -40°C or down to -70°C. In doing so, they create dry, thoroughly under-saturated compressed air in which no further condensation takes place and thus no formation of liquid water can occur at compressed air temperatures above the pressure dew-point.
Series DPS 10-100 adsorption dryers consist of welded and coated steel vessels, which are pressure-rated up to 16 bar, and practically leak-free valve blocks with large flow cross-sections and thus low differential pres-sure. The valves are individually controlled with a time delay which means there is no overlap. The dryers are operated with a 2-layer desiccant bed, consisting of 20% water resistant silica gel WS and 80% high-grade drying molecular sieve.
Series DPS 10-100 adsorption dryers are fitted with pressure gauges and a pre-filter and after-filter with differential pressure gauge as standard. The standard C1 control unit with plain text display and integrated operating elements controls all operating modes for heatless adsorption dryers and enables both independent operation of the dryer as well as integration into the control system of an existing compressed air station.
In conjunction with an optional dew-point sensor, the adsorption dryer can be operated depending on the load in variable cycle mode and thus typical energy savings of 20-70% can be achieved.
