The Yamato DNE-811 is the 300 L, floor-standing member of the DNE energy-saving programmable oven family (brochure model DNE810) — a forced-circulation constant-temperature oven rated to 210 °C with microcomputer PID control and 32-step program operation. It is the large-capacity, 200 V single-phase unit for high-throughput drying, curing, and conditioning where 300 L of chamber volume and a tall load height are required.

Application Profile
The 300 L DNE-811 targets high-throughput and tall-load dry-heat processing:
- High-volume batch drying — large glassware sets, multiple sample trays, and taller apparatus.
- Curing and heat conditioning at scale — production-adjacent coating and component processing below 210 °C.
- Facility-shared processing — 29 shelf positions accommodate mixed loads for multiple users.
- 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.
Forced circulation with an adjustable damper maintains ±2.0 °C uniformity at 210 °C even in the large 300 L chamber, with a fast ~45-minute rise time thanks to the dual 1.2 kW heaters. (See gravity-vs-forced-convection-oven.)
Design Architecture
The DNE-811 uses forced circulation via a sirocco fan / condenser motor (30 W) with two 1.2 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 tall 1000 mm-high 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. On this floor-standing size the exhaust opening is on the back surface (30 mm inner diameter), with cable and intake ports on the right surface. Casters 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, 13 A service (US nominal 220 V).
Frequently Asked Questions
What is the DNE-811's chamber capacity? 300 L in a floor-standing cabinet with a tall 1000 mm load height and 4 stainless shelves (29 shelf positions) — brochure model DNE810.
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, and a fast ~45-minute rise time from the dual 1.2 kW heaters.
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.
Does the DNE-811 have a lower-voltage option? No — this 300 L size is 200 V single-phase only; there is no 100V variant at this capacity in the family.
What electrical service does it require? 200V AC single-phase, 13A, 50/60 Hz (US nominal 220V).
Ordering & Configuration
Standard delivery includes the oven, 4 stainless punching-metal shelves (15 kg/shelf), 8 shelf brackets, and the instruction manual. Optional extra shelves (ODN22), larger cable ports, and a right-hinged door are available.
Confirm at quote: voltage and plug (the 220V-nominal variant maps to the brochure's 200V AC single-phase / 13 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 730 × 696 × 1675 mm external, ~112 kg unit (floor space, door swing, caster locking, back-surface exhaust routing); and lead time and warranty per Yamato standard capital-equipment terms.
