Procurement Specifications

3. Replacement vs. Upgrade Decision. For facilities with fewer than 5 MM440 units, direct replacement is cost-optimal. For facilities with 10+ units, a migration assessment to the Siemens G120 series may reduce long-term spare complexity. DriveKNMS can advise on both paths without obligation.
