For customers in markets with stringent cost control and environmental requirements, such as the United States and Germany, procuring decanter centrifuges should not be based solely on initial price. True value lies in the equipment's long-term operating costs. The Total Cost of Ownership (TCO) for decanter centrifuges is primarily comprised of three core elements: energy consumption, maintenance costs, and losses from unplanned downtime.

   Assessing energy efficiency is the first step in reducing TCO. Advanced horizontal screw centrifuge manufacturers achieve significant reductions in energy consumption per unit of processed material through technological innovation:

   G-Ratio Efficiency: Focuses on the specific power consumption per cubic metre of material processed to achieve your target separation factor and dewatering performance. This serves as a key indicator of equipment design quality.

Variable Frequency Drive (VFD) Technology: Advanced VFD control systems enable precise, stepless adjustment of rotational speed and differential speed. This allows the equipment to automatically adapt to optimal operating conditions based on feed volume and material properties, avoiding unnecessary ‘full load’ operation and thereby achieving significant energy savings.

   Optimised Transmission and Differential Design: Minimises mechanical friction and energy dissipation within the differential gear. The refined transmission system ensures efficient power transfer, enhancing overall energy efficiency.

Maintenance costs constitute a significant component of TCO, primarily determined by the durability and reliability of critical components:
   Core Wear-Resistant Design: The screw conveyor is the most susceptible component to wear within centrifuges. High-performance wear-resistant materials should be employed as required. For instance, protection using corrosion-resistant, high-hardness tungsten carbide alloys, or the fitting of replaceable wear-resistant protective sleeves, can extend component lifespan severalfold, substantially reducing replacement frequency and associated costs.

High-Quality Components:
   High-quality bearings and seals from internationally renowned brands are selected. The reliability of these core components directly impacts equipment uptime and maintenance cycles.
