Clean Oven 91L 3 Phase Overview
The Clean Oven 91L 3 Phase (DT411) is a forced-convection Class 100 clean oven from Yamato Scientific, supplied through LabSupplies.com as an authorized dealer. Built for temperature testing in dust-free environments, this unit holds a 91 L chamber and reaches a maximum of 360°C across an operating range of ambient +30 to 360°C.
Chamber construction pairs a stainless steel interior with an exterior of chrome-free electrogalvanized carbon steel finished in a chemical-proof, baked-on coating. A V type controller shows power consumption, CO2 emissions, and heater manipulated variables directly on the panel. Three-color indication signals HEPA filter replacement timing, while anti-fouling casters prevent wheel contamination during transport.
Power draws from a 220V 3-phase supply, and a phase-reversal relay detects an incorrect power source at installation. Footprint measures 52 × 35 × 76 inches at roughly 800 lbs. Manufactured in Japan, the oven carries ISO 9001:2015 and ISO 14001:2015 certification documentation.
Key Features
- Class 100 forced convection: maintains a dust-free chamber for clean temperature testing.
- V type controller: displays power consumption, CO2 emissions, and heater manipulated variables on the panel for improved visibility and operability.
- Three-color HEPA indication: signals filter replacement timing at a glance.
- Phase-reversal relay: detects incorrect power source wiring during installation for added safety.
- Anti-fouling casters: prevent wheel contamination while moving the unit.
- φ33mm cable port: larger access for routing instrumentation and sensors.
How to Choose the Right Clean Oven
Matching a clean oven to your workflow comes down to chamber size, thermal range, and the cleanliness class your process requires. Use these axes to confirm the DT411 fits your application before purchase.
- Capacity: the 91 L chamber sets how many samples or fixtures you can process per cycle, so size it to your batch load.
- Temperature range: an ambient +30 to 360°C span covers most curing, drying, and burn-in protocols; verify your target set point sits inside it.
- Cleanliness class: Class 100 forced convection suits dust-sensitive testing where particulate contamination would compromise results.
- Voltage and power: this model requires a 220V 3-phase circuit, so confirm your site service before installation.
- Footprint and mobility: at 52 × 35 × 76 inches and about 800 lbs, plan floor space and use the anti-fouling casters for positioning.
- Monitoring and safety: the V type controller and phase-reversal relay matter where energy reporting and installation safeguards are priorities.
