Clean Oven 91L 3 Phase Overview
The Clean Oven 91L 3 Phase (model DE411) is a forced-convection cleanroom oven from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Engineered for Class 100 temperature testing in dust-free environments, it delivers a working range of ambient +30 to 260°C across a 91-liter chamber.
Interior surfaces use stainless steel sheet metal, while the exterior is chrome-free electrogalvanized carbon steel finished in a chemical-proof, baked-on coating. A V-type controller improves visibility and operability, displaying power consumption, CO2 emissions, and heater manipulated variables on the panel. HEPA filter replacement timing reads through a three-color indicator.
Power draws from a 220V 3-phase supply, with a phase-reversal relay that flags incorrect wiring at installation. Manufactured in Japan, the unit weighs 750 lbs and measures 49 × 39 × 77 inches. Yamato backs production with ISO 9001:2015 and ISO 14001:2015 certification.
Key Features
- Class 100 forced convection: dust-free chamber suited to temperature testing of sensitive components.
- V-type controller: improved visibility and operability, with power consumption, CO2 emissions, and heater manipulated variables shown on the panel.
- Three-color HEPA indicator: filter replacement timing is read at a glance.
- Phase-reversal relay: detects an incorrect power source at installation for added wiring safety.
- Anti-fouling casters: resist wheel contamination during transport between work areas.
- φ33mm cable port: larger pass-through accommodates more instrumentation wiring.
How to Choose the Right Clean Oven
Selecting a clean oven means matching chamber size, thermal range, control style, and site power to your testing protocol. Use the criteria below to confirm the DE411 fits your workflow.
- Chamber capacity: the 91-liter interior sets how many parts or sample trays you can process per cycle.
- Temperature range: an ambient +30 to 260°C span covers most curing, drying, and heat-soak tests; verify your protocol stays within it.
- Control type: the V-type controller adds on-panel power and CO2 monitoring, useful for energy-aware facilities.
- Voltage and phase: this unit requires a 220V 3-phase circuit, so confirm your installation point supplies three-phase power.
- Footprint and weight: at 49 × 39 × 77 inches and 750 lbs, plan floor space and a delivery path with adequate clearance.
- Safety features: the phase-reversal relay and three-color HEPA indicator support correct setup and maintenance scheduling.
