High Temperature Tublar Furnace
Our Tubular Furnaces are the definitive choice for high-purity, continuous, or batch-type controlled atmosphere thermal processing. Engineered to operate at temperatures ranging from 550°C to 1800°C, these rugged thermal systems are designed for applications requiring precise temperature uniformity, exceptional atmosphere integrity, and flexible cycle management. Unlike standard box systems, our tubular furnaces process materials inside sealed quartz or high-alumina ceramic work tubes—making them ideal for delicate specimens, strict gas-purging applications, and chemical vapor deposition processes. Whether you are performing standard materials testing or specialized high-temperature sintering, our systems deliver the reliability your production line demands.
Key Features & Technical Specifications
Standard Features
- Heavy-Duty
Construction: Built with a reinforced structural steel outer casing to
ensure long-term durability and eliminate structural warping under
continuous heat.
- Advanced
Multi-Zone Heating: Strategically positioned heating elements
surrounding the process tube ensure balanced radiant heat and excellent
radial and linear temperature uniformity across the uniform hot zone.
- Precision
Control Systems: Equipped with digital PID micro-processors,
programmable multi-segment ramp/soak profiles, and high-visibility digital
displays.
- Comprehensive
Insulation: Double-walled casing configuration paired with multi-layer
high-grade insulation minimizes cold-face casing temperatures and
maximizes energy efficiency.
