Inert Oven Programmable 95L Overview
The Inert Oven Programmable 95L (model DN411IE) from Yamato Scientific creates a non-oxidizing process environment by purging its 95 L chamber with nitrogen gas. Heat treatment and heat-resistance testing run across a +15 to 360°C operating range. LabSupplies.com supplies this oven as an authorized Yamato Scientific dealer.
Chamber interiors use stainless steel, while the exterior is chrome-free electrogalvanized carbon steel finished with a chemical-proof baked-on coating. Interactive key input drives setup. Programmable control supports up to 99 steps across 99 patterns with a repeat function, plus a calibration offset, power-failure recovery modes, and saved user configuration data.
Power requirements are 220V. Footprint measures 36 × 36 × 46 inches (L×W×H) at 290 lbs, so verify bench or floor clearance before delivery. Manufactured in Japan, the unit ships under Yamato's ISO 9001:2015 and ISO 14001:2015 quality and environmental management systems.
Key Features
- Nitrogen atmosphere: N₂ gas is introduced into the chamber to produce a non-oxidizing environment, with controllable flow amount.
- Temperature range: operates from +15 to 360°C for heat-resistance testing and heat treatment.
- Programmable control: stores up to 99 patterns of 99 steps each with a repeat function.
- Operation modes: program operation, calibration offset, power-failure recovery selection, and user configuration saving.
- Safety package: self-diagnostic functions, digital setting, independent overheat prevention device, and an electric leakage breaker.
- Door switch protection: fan and heater turn off automatically if the door is opened during operation.
How to Choose the Right Inert Oven
An inert oven is specified around the process atmosphere, thermal demand, and the control precision your protocol requires. Match these axes to your application before purchasing.
- Capacity: the 95 L chamber sets how many parts or sample trays you can process per cycle; size it to your batch volume.
- Temperature range: a +15 to 360°C ceiling determines which heat-treatment and heat-resistance protocols the oven can run.
- Atmosphere control: controllable N₂ flow matters when oxidation must be suppressed during curing or annealing.
- Control type: programmable 99-step, 99-pattern operation suits repeatable, multi-stage profiles versus simple fixed-setpoint work.
- Voltage: confirm a 220V supply and a suitable dedicated circuit are available at the install site.
- Footprint and weight: at 36 × 36 × 46 inches and 290 lbs, plan bench or floor space and delivery access in advance.

Frequently Asked Questions
What is the temperature range of the DN411IE inert oven?
The DN411IE operates from +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 external footprint?
The oven provides a 95 L chamber. External dimensions are 36 × 36 × 46 inches (L×W×H), and the unit weighs 290 lbs, so confirm clearance and access before delivery.
What power supply does the DN411IE require?
The unit runs on 220V. Verify your facility provides a matching dedicated circuit ahead of installation.
What are the chamber and exterior made of?
The interior is stainless steel. Its exterior is chrome-free electrogalvanized carbon steel coated with a chemical-proof baked-on finish.
How does the oven maintain a non-oxidizing environment?
Nitrogen gas is introduced into the chamber to displace oxygen. The N₂ flow amount is controllable to suit the process during heat treatment.
Can processes be programmed and repeated?
Yes. The controller stores up to 99 patterns of 99 steps each with a repeat function, plus calibration offset and power-failure recovery modes.
