The DN C compact booster package – more than just a space-saver


Our unique and compact power house with a footprint of only 2.35 m²

This complete system has it all: Featuring a new design and a footprint approximately half the size of previous models, the DN C looks good both on the inside and outside. The new component layout not only ensures optimised cooling air flow, but also provides maintenance access.

Moreover, the updated SIGMA CONTROL 2 controller offers new, multiple monitoring and control options with a number of interfaces – including for connection to master controllers – with dynamic control.

Performance parameters:

  • 22 – 45 kW
  • Initial pressure up to 13 bar – discharge pressure up to 45 bar
  • Flow rate: 2.9 – 19.60 m³/min

Optional features:

The system is available as an air- or water-cooled version. Versions for nitrogen recovery, or a closed variant without external air (N2 version), are also available.

Applications:

PET bottle production, process air applications, nitrogen production, high pressure for test stations (e.g. brakes, coolers, etc.), test stations for pressure checks, burst pressure tests, and pulse tests.

Your advantages

  • Compact:
    This unique compact package is space-saving and powerful: no compromises in performance, reliability or energy efficiency.
  • Minimal installation effort:
    The DN C is delivered ready for connection to the electricity supply. The system can be configured for a large number of applications, including self-monitoring applications.
  • Service cost savings:
    thanks to the new design with access from the front. This is made possible due to the new component layout, which also reduces maintenance effort, e.g. when performing belt changes.

Energy cost savings
Life-cycle costs

High-quality premium efficiency electric motors deliver unparalleled efficiency for remarkably low power consumption. Their low operating temperature provides an added advantage.

 

Product details

New design for improved user-friendliness, greater efficiency and flexibility

  • Extended service life:
    The motor and airend have been decoupled from the rest of the machine. The control cabinet, cooler, fan and pipework are therefore significantly less affected by vibrations.
  • Optimised access for maintenance work:
    Side view with air cooler installed – better access once again here thanks to easily removable panel
  • Improvement for maintenance work:
    Belt change, solenoid valve servicing (nitrogen version) or replacement of dirt trap on inlet valve
