DX/DN: Oil-free reciprocating piston booster, 37-315 kW / 54-422 hp.

Customer benefits

  • Certified 100% oil-free – DX/DN boosters add no oil to your process. If the air or nitrogen entering the booster complies with ISO 8573-1 class 0 certification (2010), then the air or nitrogen will comply with class 0 at the outlet. CLASS 0 means zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and zero risk of damaging your company’s hard-won professional reputation.
  • Nitrogen-ready – We adapt the piston rings and packing rings to nitrogen composition, dew point and purity. We supply DX/DN with or without a canopy (gas detection).
  • Energy savings – DX/DN boosters with two compression stages are also available in Variable Speed Drive versions, allowing for 35% energy savings due to:
    – Unload losses are reduced to a minimum
    – Load/no load transition losses are eliminated
    – Precise pressure control allows a tighter pressure band and a lower average working pressure, resulting in reduced energy consumption.
  • Use your energy twice – Compression creates heat that is normally wasted in coolers. Energy recovery systems enable the recovery of most of the heat. The heat is directly usable as a source of energy in the form of hot water. The hot water can be used for showers, space heating, steam boilers, processes etc…
  • Easy installation – Fitted on a concrete base-plate, the DX/DN booster comes as an all-in-one package. The compact design eliminates the need for extras and accelerates installation, saving you time and money.
