Product Description
The Yamato DN-611IE is a 223 L inert gas oven: a forced convection oven that runs its entire cycle under a nitrogen blanket instead of air. Everything that oxidises during heating — solder joints, catalysts, lithium materials, polymers, activated carbon, metal powders — comes out the way it went in.
The number that matters on this machine is the nitrogen substitution time: approx. 70 min to bring the chamber down to 2 % oxygen. That is your purge cost and your cycle overhead on every single run, and it is the figure to compare against any other inert oven you are considering.
Key Features
- Full nitrogen atmosphere operation with built-in flow meter, up to 30 L/min
- Room temperature +15 °C to 360 °C — higher than a standard drying oven
- ±0.2 °C adjustment accuracy and ±3 °C uniformity at 360 °C
- Programmable to 99 steps or 99 patterns with repeat
- Integrated power consumption, CO₂ and heater output monitoring
- Operation time integration to 65,535 hours for maintenance and validation
- 223 L stainless chamber, 17 supports / 30 mm pitch, 30 kg per shelf

Installation requirements
This oven requires a nitrogen supply (not included) and a single phase 220 V circuit with a hard-wired connection — there is no plug. Because the chamber is purged with nitrogen, the room needs adequate ventilation and, depending on your safety assessment, an oxygen depletion monitor. Confirm both before ordering.
