The Yamato DH-832 is a 512 L large forced-air fine oven with high-accuracy control to 300 °C on 3-phase power. The high-temperature counterpart to the DF-832, the Yamato DH-832 pairs an 800 mm cubic chamber with a 6.9 kW heater and glass-wool-plus-ceramic-fiber insulation to hold ±1.0 °C fluctuation at 300 °C. It is the 300 °C, 512 L model of Yamato's large fine-oven range.

Application Profile
The 512 L DH-832 is a production-scale precision oven for drying, curing, and conditioning large parts or full batches up to 300 °C. Forced air circulation holds ±1.0 °C fluctuation at 300 °C across the 800 mm cubic chamber, with ten shelf positions for dense loading. Glass-wool-plus-ceramic-fiber insulation supports the higher ceiling, and accumulated power/CO₂ monitoring with user setting save/restore suit documented, repeatable production processes.
Why the Yamato DH-832 reaches 300 °C at 512 L
The DH-832 is the DF-832's high-temperature sibling: same chamber and controls, but a larger 6.9 kW heater, upgraded ceramic-fiber insulation, and a 20 A 3-phase service to hold 300 °C. That 100 °C of extra headroom is the reason to choose DH over DF at this scale; if the process stays at or below 200 °C, the DF-832 is more economical. (See laboratory-oven-selection.)
Frequently Asked Questions
What temperature range does the Yamato DH-832 reach? Room temperature +15 °C to 300 °C, with ±1.0 °C fluctuation at 300 °C.
How large is the chamber? 512 L — an 800 × 800 × 800 mm cubic chamber with 10 shelf positions at 76 mm pitch.
What power supply does it require? 3-phase AC220V, 20 A (Japanese nominal 200 V) — a 3-phase circuit is required.
How is it different from the DF-832? Same 512 L 3-phase fine oven; the DH-832 reaches 300 °C (vs 200 °C) using a 6.9 kW heater (vs 4.5 kW) and added ceramic-fiber insulation.
Is it programmable? Yes. It offers program operation up to 99 steps / 99 patterns with repeat, timed auto-start/stop, and user setting save/restore.
Ordering & Configuration
quote-based. The DH-832 is a capital 3-phase fine oven sold through a quote. At quote we confirm the 3-phase 220 V service, your process temperature and program profile within 300 °C, rigging and floor space for the 1500 × 1015 × 1330 mm, ~350 kg cabinet, and exhaust routing. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the DH-832.
DF/DH 832/1032 large fine-oven range: DH-832 (512 L, 300 °C, this unit) / DH-1032 (1000 L, 300 °C) and DF-832 (512 L, 200 °C) / DF-1032 (1000 L, 200 °C). Pick DH for 300 °C and DF for 200 °C; pick 832 for 512 L and 1032 for 1000 L. For smaller single-phase chambers use the DF/DH 412/612 series; for 500 °C use the DH-650Z.
