Yamato DN Series Inert Gas Ovens are designed for precise heat treatment and thermal testing in non-oxidizing environments. By introducing nitrogen (N₂) into the chamber, these ovens enable controlled atmosphere processing, making them ideal for sensitive materials and demanding thermal cycles.
- Models: DN411IE, DN611IE
Features:
- Supports heat resistance testing and heat treatment up to 360°C
- Intuitive operation using interactive key inputs
- Programmable controller supports up to 99 steps and 99 patterns with repeat functionality
- Calibration offset, power failure recovery, and user configuration save/load functions included
- Nitrogen flow rate is adjustable with integrated flow meter
Safety Features:
- Self-diagnostic functions for sensor failure, SSR short, heater disconnection, and more
- Independent overheat prevention and electric leakage breaker
- Key lock for secure operation
- Door safety switch disables heater and fan when door is open
- Resin-coated door and chamber for added safety during inert operation
