Inert Oven Programmable 223L Overview
The Yamato Scientific Inert Oven Programmable 223L (model DN611IE) is a 223 L mechanical convection oven engineered for heat treatment and temperature testing in a non-oxidizing atmosphere. Nitrogen (N₂) gas is introduced into the chamber to displace oxygen, supporting a working range of +15 to 360°C. LabSupplies.com is an authorized Yamato Scientific dealer.
Construction pairs a stainless steel interior with a chrome-free electrogalvanized carbon steel exterior finished with a chemical-proof baked-on coating. A controllable N₂ flow regulates the inert environment, while a door switch cuts fan and heater power if the door opens during a run. Safety layers include self-diagnostics, an independent overheat prevention device, and an electric leakage breaker.
This DN611IE operates on 220V and arrives as a single floor-standing unit measuring 40 × 48 × 55 inches and weighing 380 lbs. Manufactured in Japan, the oven ships under Yamato's ISO 9001:2015 and ISO 14001:2015 certified quality and environmental management systems.
Key Features
- Inert N₂ atmosphere: nitrogen gas is fed into the chamber to create a non-oxidizing environment for sensitive heat treatment.
- Programmable control: a 99-pattern, 99-step controller with repeat function supports complex multi-stage temperature profiles.
- Operation modes: program operation, calibration offset, power-failure recovery selection, and user configuration saving via interactive key input.
- Controllable gas flow: N₂ flow amount is adjustable to tune the inert condition for the application.
- Layered safety: self-diagnostic functions, independent overheat prevention device, digital setting, and electric leakage breaker.
- Door interlock: opening the door during operation turns the fan and heater OFF automatically.
How to Choose the Right Inert Oven
An inert oven selection hinges on matching chamber size, temperature ceiling, and control sophistication to your process while confirming site power and floor space. Use the criteria below to align the unit with your workflow.
- Capacity: the 223 L chamber suits batch heat treatment and larger sample loads; size the volume to your throughput.
- Temperature range: a +15 to 360°C span covers most curing, annealing, and drying tasks that must avoid oxidation.
- Control type: programmable 99-step, 99-pattern control is essential when processes require ramped or repeated profiles rather than a single setpoint.
- Voltage: confirm your facility supports the 220V supply before installation.
- Footprint and weight: verify the 40 × 48 × 55 inch envelope and 380 lb load against your bench or floor plan.
- Safety features: independent overheat protection, leakage breaker, and door interlock matter for unattended or extended runs.

Frequently Asked Questions
What is the temperature range of the Yamato DN611IE inert oven?
The DN611IE operates across +15 to 360°C. This range supports heat resistance testing and heat treatment within a non-oxidizing nitrogen atmosphere.
What is the chamber capacity and overall size?
The chamber holds 223 L. The complete unit measures 40 × 48 × 55 inches (L × W × H) and weighs 380 lbs, so plan floor space and handling accordingly.
What voltage does the DN611IE require?
This oven runs on 220V. Confirm your facility provides a compatible supply before installation.
How does the oven create an inert environment?
Nitrogen (N₂) gas is introduced into the chamber to displace oxygen and form a non-oxidizing atmosphere. The N₂ flow amount is controllable to tune the inert condition.
What materials are used in the chamber and exterior?
The interior is stainless steel. The exterior is chrome-free electrogalvanized carbon steel with a chemical-proof baked-on finish.
Can the DN611IE run multi-step temperature programs?
Yes. The controller stores up to 99 patterns and 99 steps with a repeat function, plus calibration offset and power-failure recovery mode selection.
