DSP CE Series Industrial Oil Free Rotary Screw Air Compressor

RELIABLE HITACHI ENGINEERED PACKAGE DESIGN BASED ON MORE THAN 50 YEARS OF OIL FREE ROTARY SCREW EXPERIENCE

The DSP Series brings advanced oil free operations right where it is needed: your facility!

Built on Hitachi engineering, the DSP is designed to supply oil free air reliably and efficiently— today and tomorrow.

  • Innovative Air End Construction
  • Patented Oil Mist Remover (OMR) 
  • Motorized Isolation Valve (MIV) 

Models vary by region. Please contact your Sullair sales representative for more details.

INNOVATION AIR END CONSTRUCTION
Key features: 

  • Rotor design, material and coating optimized
    for efficiency
    • Stainless steel rotors in 1st and 2nd stage
    • Patented PTFE free rotor coating
    • Rotor housing coated internally

Benefits: 

  • All aspects of the air end have been carefully engineered to provide long life and high efficiency
    • The stainless steel rotors, patented rotor coating and coated housing provide long life of air end

PATENTED HIGH PRE-COOLER DESIGN (AIR COOLED UNITS)
Key features:

  • Stainless steel high pre-cooler placed before aftercooler

Benefits:

  • Helps prevent thermal fatigue and premature failure of the aftercooler, providing higher reliability and durability

MOTORIZED ISOLATION VALVE (MIV)
Key features:

  • Located at the compressed air discharge, the MIV helps avoid migration of moisture back into the compressor package when the DSP is not running
    • Opens when the motor is running and closes when the motor is off

Benefits:

  • Provides additional protection for the compressor against downstream humidity – one of the biggest enemies of oil free screw compressors

OIL MIST REMOVER (OMR)
Key features:

  • Removes oil mist from gearcase with 99.99% efficiency
  • Maintains gearcase at negative pressure

Benefits:

  • Recaptured oil mist returned reducing gearcase top offs needed — saving you money
  • Helps ensure a cleaner production environment around the compressor

CAPACITY CONTROL SYSTEM
Fixed speed
Key features:

  • Spool type — simple design
  • Pneumatically controlled
  • Designed to operate 1 million cycles/year

Benefits:

  • High reliability and durability
  • Lower maintenance cost
  • Longer maintenance intervals

Variable speed drive
Key features:

  • No inlet valve on VSD
  • Two speed reduction
  • Turndown works always in the most efficient range of specific power, below turndown DSP works load/unload at minimum point of turndown

Benefits:

  • No restriction means no air losses at inlet
  • Minimize power consumption at unload condition
  • Power consumption at no load is reduced up to 30% vs fixed speed of same model
    • More efficient at low capacities vs VSD from others that run with larger turndown and a very inefficient specific power at lower points of turndown

MOTORS, INVERTERS AND PHASE MONITOR
Key features:

  • Hitachi motors
    • IE3, TEFC and IP55 (22–240 kW Models)
    • DCBL-PMM on DSP37V, DSP55V and DSP75V models
  • VSD fan motors on DSP22–120
  • Hitachi inverters
  • Phase monitor standard

Benefits:

  • Support provided in house — no external motor suppliers to navigate
  • Motors are high efficiency and very compact
  • More efficient cooling system
  • Support provided house — no external inverter suppliers to navigate
  • Protects the compressor against improper reverse rotation at startup

WARRANTY INFORMATION:

  • All DSP Series Compressors feature a 3 year package warranty when continuously serviced with genuine DSP parts.
