TWO-STAGE ROTARY SCREW AIR COMPRESSORS 90-250 KW

FS Curtis NXHE 90 – NXHE 260

Flow:- 19.5- 54.3 CMM

  • Two-stage air compressors are closer to the ideal isothermal compression
  • Reduced leakage increases volumetric efficiency
  • Saves 10-15% of energy compared to single stage compressors
  • Increases flow 10-15% compared to single stage compressors
  • Lower pressure differential increases efficiency and reliability
  • Low heat load

O LS Technology

The ultimate in system protection and reliability
• Protects critical cc•mponents from compressor-generated neat
• Compartmentaliæ:i air flow design and oversized aftercooler
• Extends component lite and reduces downtime

Energy-efficient Two-stage airend

Energy-saving and Eco-friendly
• Patented airend design integrates the first and second stage rotors into
one airend
• Oil is injected between the first and second stages to cml the air and
optimize efficiency
• Splitting the compression cycle into Two-stages reduces the axial and

thrust loading to which improves service lite ot airend and bearings
• Twcpstage compression significantly reduces noise

Effectively integrated overall design

Designed for low COSI ot ownership, easy service little down time
• Sate. etticieM air tilter system
• Independent bearing lubrication
• High efficiency. %sy-to-maintain oil separator
• IE3 high efficiency motor
• End face sealed to prevent leakage
• Connections utilize O-ring face seals lot leak—free performance
• Asbestos-tree gaskets protect operator health

KSRengineers Service Kits include all genuine parts and wear parts for the respective maintenance and ensure optimum operation of the systems.
