Buying Guide
What to consider when choosing a waste oil processing or disposal solution
- Oil throughput: For centrifugation, confirm hourly processing capacity to match your volume needs.
- Oil types: Some units handle a mix of waste vegetable oil, motor oil, and other fluids; verify compatibility.
- Purification vs. disposal: Centrifuges purify; solidifiers help with disposal. Choose based on how you plan to reuse or discard oil.
- Maintenance needs: Centrifuges require regular cleaning and parts upkeep; solidifiers are simpler but add waste to disposal streams.
- Safety and handling: Proper ventilation, fire safety, and spill containment are important in any oil-handling setup.
- Cost of ownership: Consider initial investment, consumables, and ongoing disposal costs.
