The Yamato DNE-911 is the 540 L flagship of the DNE energy-saving programmable oven family (brochure model DNE910), a forced-circulation constant-temperature oven rated to 210 °C with microcomputer PID control and 32-step program operation. It is the largest, highest-throughput unit in the range, with dual blowers and dual heaters for uniform dry heat across its 540 L chamber.

Application Profile
The 540 L DNE-911 targets the highest-volume dry-heat processing in the family:
- Large-batch and production-adjacent drying. High glassware and sample throughput at uniform temperature.
- Curing and heat conditioning at scale. Coatings and components across a wide, deep chamber below 210 °C.
- Facility-shared processing. 8 shelves and 29 shelf positions accommodate mixed multi-user loads.
- Extended soak and multi-stage methods. Long stabilization runs with the operating-hours counter, plus up to 32 program steps with auto-start / auto-stop scheduling.
The dual sirocco blowers and dual 1.5 kW heaters maintain ±2.0 °C uniformity at 210 °C across the wide 1090 mm chamber, the reason to choose forced circulation over natural convection at this scale. (See gravity-vs-forced-convection-oven.)
Design Architecture
The DNE-911 uses forced circulation driven by two sirocco fans / condenser motors (30 W × 2) with two 1.5 kW stainless pipe heaters, governed by a microcomputer PID controller (VI CR3 type) reading a K-thermocouple. The SUS304 stainless interior and glass-wool insulation support uniform heating across the large 540 L chamber. Operation modes include fixed temperature, auto-start, auto-stop, and 32-step program operation, plus timer, clock, total-operating-hours counter, fan control, and calibration offset. The exhaust opening is on the back surface (30 mm inner diameter); casters (two on this size) should be locked in place per the brochure.
Safety includes an earth-leakage breaker, an independent overheating-prevention device, a key-lock function, and self-diagnostics for sensor error, heater disconnection, triac short circuit, and automatic overheating prevention. This model is specified for 200V AC single-phase, 16 A service (US nominal 220 V).
Frequently Asked Questions
What is the DNE-911's chamber capacity? 540 L, the largest, highest-throughput unit in the DNE energy-saving programmable oven family (brochure model DNE910).
What temperature range and uniformity does it deliver? Room temperature +10 °C to 210 °C, with ±0.5 °C adjustment accuracy and ±2.0 °C distribution at 210 °C, maintained by dual sirocco blowers and dual 1.5 kW heaters.
Why forced circulation rather than natural convection? The dual blowers keep ±2.0 °C uniformity across the wide 1090 mm chamber and recover faster after door openings, the reason to choose forced circulation at this scale.
How many program steps does it support? Up to 32 program steps with auto-start / auto-stop scheduling, plus fixed-temperature, auto-start and auto-stop modes.
What electrical service does it require? 200V AC single-phase, 16A, 50/60 Hz (US nominal 220V), a connection best completed by a licensed contractor.
Ordering & Configuration
Standard delivery includes the oven, 8 stainless punching-metal shelves (15 kg/shelf), 16 shelf brackets, and the instruction manual. Optional extra shelves (ODN24), larger cable ports, and door options are available.
Confirm at quote: voltage and plug (the 220V-nominal variant maps to the brochure's 200V AC single-phase / 16 A rating; confirm your service and have a licensed contractor complete the 200 V connection); the temperature and program profile (target ≤ 210 °C with ramp/soak steps); shelving and accessories (additional shelves for the 29-position rack); floor footprint and access against the 1220 × 696 × 1675 mm external, ~178 kg unit (floor space, door swing, dual-caster locking, back-surface exhaust routing); delivery and rigging for a unit of this size and weight; and lead time and warranty per Yamato standard capital-equipment terms.
