Compressed air treatment systems are designed for a certain rate of air flow which, when the system is operating at full load, pushes against the pressurised air in the air distribution network. However, should this resistance not be present, for example during periods of low load or downtime, it is possible that dryers and filters may be “overwhelmed” by the sudden surge in airflow that occurs when the system re-starts. DHS air-main charging systems reliably prevent this from occurring.

Thanks to a patented pulse width modulating control concept, every DHS air-main charging system is ready-prepared for all eventualities and, as is Kaeser‘s way, combines exceptional operational reliability with straightforward operation.

  • Connection diameters from G ½ to G 3 and DN 40 to DN 400
  • For systems with one or more treatment lines
  • Perfect integration thanks to various interfaces, configuration options and retrofit kits

Your advantages

  • Protection from impermissible air flow: 
    With dropping pressure, the speed of flow in the pipework will quickly increase and potentially cause an overload of all air system components. The installation of a Kaeser DHS air-main charging system guarantees the required minimum pressure and ensures reliable operation, and in particular when re-starting the system following a shut-down. 

Air receivers are an important link in the compressed air chain: as storage media or buffers for peak load demand.

The Kaeser Membrane Module (KMM) features a special flow concept for long-term drying efficiency as well as the innovative, high-density helical fibre structure of the high-performance hollow fibre membranes.

KMM dryers easily deliver pressure dew points in the minus range, even when installed where space is at a premium. They also play to their strengths when energy sources are unavailable or when used as end-point dryers in areas at risk of frost.

  • Flow rates from 0.04 to 3.97 m³/min
  • PDP from +10 °C to −40 °C (relative temperature reduction of up to 90 °C compared to inlet air temperature)
  • Optional versions with energy-saving purge air stop valve

Your advantages

  • Superior membrane design: 
    The helical structure of the extra-fine Kaeser membrane fibres results in a high-surface area separator with low space requirements. Furthermore, effective transportation of water molecules from the outside in means the external membrane pores always remain ready to channel more water (innovative Flow Concept).

HYBRITEC compressed air dryers combine the extremely low pressure dew points of desiccant dryers with the energy-saving functionality of modern refrigeration dryers. The result: outstanding flexibility and huge energy cost savings. This means that the desiccant dryer can simply be switched off during periods where more moderate DTPs are required – such as in the summer months.

  • Reliably dry, cost-effective compressed air from 12 to 150 m³/min (DTE – DTL series models)
  • PDP level can be set between −40 °C and +3 °C
  • Numerous configuration options

Your advantages

  • Maximum energy efficiency: 
    Kaeser combination dryers only require some 50 % of the energy required by heat regenerated desiccant dryers and – incredibly – just 20 % of the energy used by heatless regenerated units.
  • Cost-effective and precise, individual configuration options: 
    Combination dryers can be configured for virtually any application from standard models in our dryer range – a solution that saves money and ensures outstanding operational reliability.

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

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.
  •  

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.
