A full-size vertical vacuum furnace can vary widely in cost, generally ranging from around $200,000 to $1 million or more. The price depends on several factors, including:

1. Size and Load Capacity: Larger furnaces that can handle bigger loads tend to be more expensive.
2. Vacuum Level: Higher vacuum levels, such as ultra-high or high-vacuum systems, will increase the cost.
3. Quenching Capabilities: If you need a 6-bar or higher gas quench capability (like what you have with your Vac Aero furnaces), the cost can be significantly higher.
4. Heating Elements and Temperature Range: Furnaces designed for higher temperatures, or with advanced heating elements (such as molybdenum or graphite), will cost more.
5. Automation and Controls: Advanced control systems for precise temperature control and automation options also add to the price.

Customization: Furnaces designed to meet specific process requirements, like those needed for high-speed steel and tool steel, may have additional customization costs.

Key Considerations for Your Purchase

• Application-Specific Needs: Look at which models align best with your application (e.g., hardening high-speed steels or large batch loads).
• Energy Efficiency: Some models offer energy-saving features, which can be beneficial for long-term cost savings.
• Control System Integration: Ensure the furnace integrates well with your existing control systems and has a user-friendly interface.

Most manufacturers also typically provide maintenance packages, training, and installation support, which can be critical for operation and cost management.
