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.
