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.
