Booster Packages for High Pressure Compressed Air Applications


Fully enclosed package boosts pressure where needed

The design of the DN-C booster package has a smaller footprint (approximately half the size of previous models) with a component layout that not only ensures optimized cooling air flow, but also provides easy maintenance access.

The 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.

DN-C Series Models

Benefits, Features, and Applications



  • Compact design without compromising  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.
  • The Sigma Control 2 provides maintenance and service reminders and history, helping to reduce your maintenance costs.
Standard features:
  • Maximum ambient temperature up to 113°F at 4.5:1 compression ratio.
  • Air-cooled
  • UL508A control cabinet
  • UL approved motors
  • NPE motors with 1x PT100 sensor
  • Full enclosure with starter cabinet
  • Sigma Control 2 controller
  • Factory tested and assembled

Optional features:

  • Auxiliary heating
  • Nitrogen recovery version
  • Water-cooled version

Improved user-friendly design for 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.
  • Optimized access for maintenance work. Removable panel provides easy access to components like the air cooler shown here.
  • Three cylinder models feature an aftercooler with a high-speed fan to ensure lowest possible compressed air discharge temperatures. A water-cooled aftercooler version is also available to achieve even lower “delta T” results
