The Yamato DNE-411 is the 90 L, 220V-nominal member of the DNE energy-saving programmable oven family (brochure model DNE410) — a forced-circulation constant-temperature oven rated to 210 °C with microcomputer PID control and 32-step program operation. It is the 200 V single-phase sister of the 100V DNE-401, priced identically, for laboratories on 220 V service needing uniform, energy-efficient dry heat at 90 L.

Application Profile
The 90 L DNE-411 suits general laboratory dry-heat processing on 220 V service. It handles general drying and dehydration of glassware, samples, and prepared materials at uniform temperature, curing and heat conditioning of coatings and components on defined ramp/soak profiles below 210 °C, and constant-temperature soak and stabilization for extended holds using the operating-hours counter and program repeat. Moisture and gravimetric workflows — dry-to-constant-weight determinations — run with forced-air uniformity, and multi-stage method development is supported by up to 32 program steps with auto-start / auto-stop scheduling.
Forced circulation with an adjustable damper yields tight uniformity (±2.0 °C at 210 °C). (See gravity-vs-forced-convection-oven.)
Design Architecture
The DNE-411 uses forced circulation via a sirocco fan / condenser motor (10 W) with a 1.1 kW stainless pipe heater, governed by a microcomputer PID controller (VI CR3 type) reading a K-thermocouple. The SUS304 stainless interior and glass-wool insulation support uniform, efficient heating. 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. Cable, exhaust (top surface), and intake ports (30 mm inner diameter) are provided.
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, 6 A service (US nominal 220 V) — a licensed contractor should perform the single-phase 200 V connection per the brochure.
Frequently Asked Questions
What is the DNE-411's temperature range? Room temperature +10 °C to 210 °C, with ±0.5 °C adjustment accuracy and ±2.0 °C distribution accuracy at 210 °C.
What power supply does the DNE-411 need? 200V AC single-phase, 6 A, 50/60 Hz (US nominal 220V); a licensed contractor should perform the single-phase 200 V connection.
How does it differ from the DNE-401? The DNE-411 is the 200V (US nominal 220V) sister of the 100V DNE-401; both are the 90 L size.
Does it run programmed profiles? Yes — up to 32 program steps with fixed-temperature, auto-start, and auto-stop modes.
Why is the brochure model DNE410? DNE-411 is the price-list SKU for brochure model DNE410, the 90 L, 200V unit; all specs trace to the DNE400/410 column.
Ordering & Configuration
Standard delivery includes the oven, 2 stainless punching-metal shelves (15 kg/shelf), 4 shelf brackets, and the instruction manual. Optional stands (ON62, OT42), stacking fittings, extra shelves, larger cable ports, and a right-hinged door are available.
Confirm at quote:
- Voltage and plug — 220V-nominal variant maps to the brochure's 200V AC single-phase / 6 A rating; the 100V sister is the DNE-401. Confirm your 200 V single-phase service.
- Temperature and program profile — target ≤ 210 °C, ramp/soak steps.
- Footprint and shelving — 580 × 646 × 860 mm external; confirm bench clearance, exhaust routing, and any additional shelves, stand, or stacking fittings.
- Lead time and warranty — per Yamato standard capital-equipment terms.
