Kaeser desiccant dryers achieve pressure dew points as low as −70 °C. Enjoy reliable anti-frost protection for your control valves and lines and compressed air drying for sensitive processes at minimal cost – thanks to high-quality compressed air filters fitted as standard and efficient energy-saving controllers. Aluminium oxide desiccant ensures maximum operational reliability.

Heatless regenerated desiccant dryers are perfect for supplying low compressed air requirements and units from 12.0 m³/min can also serve as reliable redundancy systems for our extremely efficient HYBRITEC combination dryers.

For compressed air requirements of 17.6 m³/min and higher, our heat regenerated desiccant dryers feature efficient and space-saving unit design.

 

a) Heatless Regenerated Desiccant Dryers, 0.15 - 0.75 m³/min

Minimal space requirement, huge savings
DC series compact desiccant dryers easily fit inside cramped containers and deliver exceptional reliability and efficiency. For instance, they are able to dry air to a pressure dew point of −40 °C within a ten-minute cycle. During this process, the dryer switches between the two desiccant chambers only once every five minutes. This is an important feature for low-wear operation which also conserves compressed air.

• PDP to −70 °C
• Flow rate 0.15 to 0.75 m³/min
• ECO-DRAIN electronic condensate drain (E-Pack option)

Your advantages

• Space-saving and easy to install:
  The compact design of the protective all-round enclosure makes our small desiccant dryers ideal for decentralised compressed air treatment. They are also perfect for wall installation.
• The 10-minute cycle also makes them highly efficient:
  Keeping the number of switching sequences between the chambers to a minimum also reduces the load burden on the valves and desiccant. Furthermore, only 1.3 % of the compressed air is diverted for pressure build-up following the regeneration phase.
• Long-term reliability:
  The tried-and-trusted valve technology ensures trouble-free cycling over the long-term, whilst the durable desiccant chamber is designed for continuous operation for at least 10 years.

b) Heatless Regenerated Desiccant Dryers from 1.17 to 154.53 m³/min

Efficient and reliable to PDP −70 °C
The powerful desiccant dryers of the DC series, including both compact and large models, shine thanks to extremely low service and operation costs whilst easily overcoming the most challenging operational conditions. In particular, their minimal regeneration air requirements and the ECO-CONTROL energy-saving controller ensure rapid amortisation of investment costs.

• PDP to −70 °C
• Flow rate 1.17 to 154.53 m³/min
• ECO CONTROL BASIC or ECO CONTROL with innovative, trend-detecting pressure dew point control (E-Pack option)
• Can be optionally coupled to an ACT activated carbon adsorber, for technically oil-free compressed air to meet the strictest requirements

Your advantages

• Low operating costs:
  Desiccant dryers from the DC 12 model and higher feature extremely low regeneration air requirements – thanks to optimal flow dynamics through the high-quality desiccant. Moreover, the resulting heat from the adsorption process is channelled into the regeneration process.
• Energy-saving, intelligent control:
  The ECO CONTROL controller included in DC "E-Pack" versions is load-independent and employs the highly reliable trend-detection method for dew point control, which delivers maximum energy savings.
• Inexpensive service and maintenance:
  DC dryers are constructed using high-quality, extremely durable components. Inlets, outlets and filter housings are easily accessible whilst disassembly and cleaning of the silencers is highly straightforward.

c) Heat Regenerated Desiccant Dryers from 17.6 to 194.2 m³/min

Space-savers for high flow rates
The compact heat-regenerated desiccant dryers of the DW series deliver reliable drying performance down to a pressure dew point of −40 °C whilst also featuring generous fill levels of innocuous aluminium oxide desiccant. Desiccant regeneration is performed with externally heated blower air using the highly efficient reverse flow process. This boosts operational reliability whilst cutting operating costs.

• PDP to −40 °C
• Flow rate 17.6 to 194.2 m³/min
• Optionally available with ECO CONTROL DW dew point control

Your advantages

• Highly energy efficient:
  DW-series desiccant dryers take advantage of the efficient reverse flow regeneration process and are additionally equipped with high-quality heat insulation.
• Reverse flow process with safety buffer:
  DW dryers use activated aluminium oxide desiccant – a water-resistant material with extremely high mechanical stability. The generously dimensioned desiccant fill level constitutes an emergency operation reserve in extreme situations.
• Cost-effective transport:
  DW dryers feature significantly lower height compared to competitors' models, which allows for straightforward transportation of all DW models by truck (articulated lorry).
