HAUG.Sirius NanoLoc - high pressure oil-free and gas-tight compressors (11 - 30 kW)

Unique combination of high-pressure cylinders with NanoLoc® design can reach a discharge pressure up to 451 bar(abs). At the same time the hermetically sealed and entirely wear-free drive with magnetic coupling ensures compression of various gases without leaks. This system ensures no gas losses to atmosphere and no compressed gas pollution from outside.

HAUG oil-free and gas-tight compressors are environmental friendly because there is no oil disposal and gas leakage which can contaminate the environment.

NanoLoc® Design

  • Especially suitable for high pressures >101 bar(abs) because sealing without piston rings
  • No friction losses in the cylinders due to friction-free sealing
  • No wear at cylinders and very low wear of piston, thus significantly longer service life than with piston and packing rings
  • Lower overall height and very compact and simple design with only a few parts Service-friendly, components are easy to replace
  • Service-friendly, components are easy to replace
  • No water cooling required
  • Lower power consumption, since pistons move without friction in the cylinder
