Desiccant Dryer

POWERFUL, COMPACT AND RELIABLE

Made from activated aluminium oxide the DESSICANT has an exceptionally high adsorption capacity and its regeneration capability provides sustained low pressure dew point performance with minimal pres- sure loss. The desiccant is also waterproof and mechanically stable,which makes it particularly suitable for long periods of operation. Furthermore, specific pellet sizes are available to ensure optimal performance of flow diffusers and sieve plates

  • Small models DC 1.5 to 7.5
  • Compact models DC 12 to 133
  • Large models DC 169 to 1545
  • Combination with activated carbon adsorber

DESICCANT TANK

Application-specifi c design enables a million load cycles at 10 bar(g). Performance meets all requirements as per Pressure Equipment Regulation 97/23/EC. Continuous operation of at least ten years is possible.

CYCLE CONTROL

The user-friendly cycle control system from KAESER enables quick and clear pressure dew point selection of -40 °C and -70 °C.

INTERMITTENT OPERATION

An on/off controller can help save energy in systems with frequently interrupted cycle phases. “Reverse regeneration” (where the regeneration cycle uses air from the downstream air receiver) is particularly reliable, as a completely regenerated desiccant tank is always available each time the drying cycle restarts. This technique eliminates the possibility of extreme pressure dew point values from occurring at the outlet as a result of excessive loading of the desiccant.

NETWORKING WITH SIGMA AIR MANAGER

Both ECO CONTROL versions are equipped as standard with a remote on/off and fl oating contact that can be monitored for alarm situations. With the ECO CONTROL system it is possible to connect and display data from a pressure dew point measuring device via an analogue input.

QUALITY COMPONENTS

Proven valve technology guarantees trouble-free operation. Operational status can be viewed at a glance via the manometer which is fi tted to each tank. All DC compact desiccant dryers are equipped as standard with easily accessible pre- and particulate fi lters from KAESER KOMPRESSOREN.

E-PACK (OPTIONAL FOR ALL SIZES)

In this version, the upstream desiccant dryer pre-fi lter is equipped with an ECO-Drain electronic condensate drain to provide highly effective condensate removal without compressed air loss.

ECO CONTROL BASIC : SIGNIFICANT PURGE AIR SAVINGS

With Eco Control basic, the dryer is able to reduce its regeneration cycle to a value below the set rated fl ow value. For example, if the dryer is purchased with future compressed air system expansion in mind and is operating at only 80 % capacity, its regeneration time can be reduced from 4 minutes to 3.2 minutes – a purge air saving of 20 %. This feature allows drying capacity in the compressed air system to be varied according to actual demand.

SERVICE-FRIENDELY

Units feature an easy-to-read display panel with visual system overview and LEDs on the pressure switch, valve, and tank icons to provide clear, precise information regarding operational and servicing status. The exact valve switching sequence can be checked in the manual test mode.

DEPENDABLE DRYING POWER TO -70 °C

Meticulous design and quality ensure that KAESER DC series desiccant dryers operate efficiently to provide dependable low pressure dew point performance at continuous load, even under the toughest of conditions. The impressive drying results are aided by generous quantities of KAESER’s high quality ‘SIGMA Dry’ desiccant, as only a fraction of the material’s initial load is used. Consequently, this means that minimal quantities of purge air are required for desiccant regeneration, even after longer than average periods of operation. In addition, long cycle periods reduce the number of flow optimised components required for reliable, integrated performance, such as KAESER’s pre- and particulate filters.
