Advantages

  • Single-stage, direct-drive compression element maximizes efficiency and minimizes maintenance.
  • High quality water injection lubricates, cools and seals the compression process maximizing efficiency.
  • The absence of a gearbox makes oil lubrication unnecessary.
  • Low bearing loads and low speeds allow the use of sealed bearings for life that do not require oil lubrication.
  • Variable speed technology reduces energy costs.
  • Comprehensive control functions ensure safe and reliable operation, including remote communication capability.
  • Completely silenced and packaged housing reduces noise and simplifies installation.

Design

DH compressors have far fewer moving parts than comparable machines, so the number of components that can fail is lower. Reduced speeds and bearing load compensation extend the life of the compression element and reduce operating costs.

Extremely low operating temperatures of around 60°C result in near-isothermal compression. This makes the use of an internal aftercooler unnecessary, with the consequent energy savings, and reduces the pressure drop to a minimum.

Compression loads are balanced to reduce bearing loads and improve reliability:

Proven reverse osmosis filtration technology provides high quality purified water to lubricate, seal and cool the compression process. The impregnation pump allows the necessary water to be reduced to a minimum.
