Oil-free reciprocating nitrogen boosters and air boosters DX & DN(VSD)

DX&DN (VSD): advanced oil-free air and nitrogen technology

Advanced single or two-stage compression technology.
Boosts your air or nitrogen up to a wide range of pressure and flows.

The difference between DX and DN is to be found in the size:

  • DX is the smaller unit from 37 to 110 kW
  • DN is the bigger unit from 110 to 315 kW

Certified oil-free and nitrogen boosters

Our robust DX/DN boosters come as mono-stage or two-compression stage machines, compressing your air or nitrogen in a broad variety of pressure ranges:

  • up to 70 bar (e) maximum
  • flow ratios depending on your specific process needs

With a delivery of 100% oil-free ISO 8573-1 Class 0 certified compressed air or nitrogen, you minimize the risk of oil contamination in your production. This is because no oil from the compressor will ever enter your air or nitrogen network from the booster.

Main industry applications in Food and beverage, Automotive, Power, PET bottle blowing, and general industries.

No oil contamination

The booster systems are ISO 8573-1 Class 0 certified, meaning that no oil from the booster will enter your air or gas network, minimizing production downtime.

Adaptable booster design
The DX/DN nitrogen gas boosters are adaptable in design: depending on the kind of gas you want to boost for your process, they can be delivered with or without a canopy.
Plug and play compressor boosters
DX/DN (VSD) boosters are installed in no time thanks to their compact design, integrated components, and concrete base. Minimal installation costs


Energy saving nitrogen and air boosters

You can save more thanks to the integrated heat recovery system; which enables you to re-use the heat of compression as hot water elsewhere in your production system (e.g. like heating spaces or, showers).

Safety first: the Elektronikon® unit controls the pressure and flow, and protects the unit from failure due to the internal sensors.

Our innovative design and use of advanced materials has allowed us to simplify the design of the unit as well as increase energy efficiency, . DX/DN boosters are all-in-one packages, very easy to install and maintain, and saving you time and money.

High energy savings
Variable Speed Drive (VSD) adjusts the flow automatically according to your needs, reducing your compressed air or nitrogen energy bills by approximately 35%.
Re-use your energy
The integrated energy recovery system uses the heat of compression for hot water elsewhere in your production system like boilers, space heating…
Control your process
The Elektronikon® unit saves you money by controlling the pressure and flow to maximize efficiency and protects your equipment from failure.
