The Yamato DNE-611 is the 150 L, 220V-nominal member of the DNE energy-saving programmable oven family (brochure model DNE610) — 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-601, priced identically, for 220 V laboratories needing 150 L of uniform, energy-efficient dry heat.

Application Profile
The 150 L DNE-611 suits mid-volume laboratory dry-heat processing on 220 V service — including gravimetric dry-to-constant-weight determinations at higher throughput. Typical uses:
- Batch drying and dehydration — larger glassware sets and sample trays at uniform temperature.
- Curing and heat conditioning — coatings and components on defined ramp/soak profiles below 210 °C.
- Constant-temperature soak and stabilization — extended holds with program repeat and the operating-hours counter.
- Multi-stage method development — 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) across the 150 L chamber. (See gravity-vs-forced-convection-oven.)
Design Architecture
The DNE-611 uses forced circulation via a sirocco fan / condenser motor (30 W) with a 1.34 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 heating across the 150 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. 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, 7.5 A service (US nominal 220 V) — the single-phase 200 V connection should be made by a licensed contractor per the brochure.
Frequently Asked Questions
What temperature range does the DNE-611 reach? Room temperature +10 °C up to 210 °C, with ±0.5 °C adjustment accuracy and ±2.0 °C temperature distribution at 210 °C.
What voltage does the DNE-611 require? 200V AC single-phase, 7.5 A, 50/60 Hz (US nominal 220 V). The 100 V sister model is the DNE-601.
How large is the chamber, and what shelving is included? 150 L, with internal dimensions of 600 × 500 × 500 mm. It ships with 2 stainless punching-metal shelves rated 15 kg each and 13 shelf-bracket steps at 30 mm.
Is the DNE-611 forced or natural convection? It is a forced-circulation oven, using a sirocco fan / condenser motor (30 W) with an adjustable damper for ±2.0 °C uniformity across the chamber.
How many program steps does it support? Up to 32 program steps, plus fixed-temperature, auto-start, and auto-stop operation, governed by a microcomputer PID controller.
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, OT62), stacking fittings, extra shelves, larger cable ports, and a right-hinged door are available.
At quote, confirm your 200 V single-phase service (the 220V-nominal variant maps to the brochure's 200V AC / 7.5 A rating; the 100 V sister is the DNE-601), your target temperature and program profile (≤ 210 °C with ramp/soak steps), any additional shelving, stand, or stacking fittings, and bench or floor clearance for the 730 × 696 × 910 mm external footprint with exhaust routing. Lead time and warranty follow Yamato standard capital-equipment terms.
