Description
Compressed air drying on a small scale – with the technology and features of a large dryer
Series DPS 1-8 adsorption dryers, optionally available as DPS 1-8 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 undersaturated 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 1-8 adsorption dryers consist of a powder-coated aluminium profile body which is pressure-rated up to 16 bar. Fully integrated, leak-free valve plates with large flow cross-sections resulting in low differential pressure are connected to the body. The switch-over valves are freely accessible in the lower valve plate and are individually controlled without any 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 1-8 adsorption dryers are equipped with pressure gauges and a pre-filter and after-filter, which can be fitted in various ways, as standard. Wall mounting is simple and easy using commercially available wall brackets. 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.
