DSP CE Series Oil Free Air Compressors

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.
