2. Lubricated Rotary Screw Compressors
Benefits of a Lubricated Compressor
- Fully Automated via Delcos Controller – Delivers the precise amount of lubricant at the right time, with no manual intervention.
- Zero Downtime – Ensures uninterrupted production.
- Fast, Cost-Effective Maintenance – Cartridge replacement is performed at 4,000 or 8,000 hours.
- Extended Life Expectancy – Rotors rarely require replacement.
- Assure Warranty Coverage – Applies to all units commissioned from 01/01/2019.
- Fixed Speed – Runs continuously and is highly efficient when operating at full capacity.
- Variable Speed – Adjusts output to match demand, using only the energy required for the needed airflow, resulting in significant energy and cost savings.
