- Innovative Air End Construction
- Oil Mist Remover
- Motorized Isolation Valve
Features&Benefits
Innovative 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 is 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 (VSD)
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
Hitachi Motors
Key features:
- IE3, TEFC and IP44 (Fixed Speed 22-240 kW models and VSD 160-240 kW models)
- TEFC, DCBL-PPM and IE4 (DSP37V, DSP55V and DSP75V models)
Benefits:
- Support provided in house - no external motor suppliers to navigate
- Motors are high efficiency and very compact
VSD Fan Motors
Available on DSP22-75
Benefits:
- More efficient cooling system
Hitachi Inverters
Benefits:
- Support provided in house - no external inverter suppliers to navigate
Phase Monitor
Benefits:
- Protects the compressor against improper reverse rotation at startup
Warranty
- All DSP Series Compressors feature a 3 year package warranty* when continuously serviced with genuine
DSP parts
