The Yamato DF-832 is a 512 L large forced-air fine oven with high-accuracy control to 200 °C on 3-phase power, designed to support high-throughput precision heat treatment. With an 800 mm cubic chamber and ±0.5 °C fluctuation at 200 °C, the Yamato DF-832 brings fine-oven uniformity and programmability to large parts and full-batch production. It is the entry model of Yamato's large 832/1032 fine-oven range.

Application Profile
The 512 L DF-832 is a production-scale precision oven for drying, curing, and conditioning large parts or full batches up to 200 °C. Forced air circulation holds ±0.5 °C fluctuation at 200 °C across the 800 mm cubic chamber, and the ten-position shelving supports dense loading. Accumulated power-consumption and CO₂ monitoring, plus user setting save/restore, make it suited to documented, repeatable production processes rather than occasional bench work.
Why the Yamato DF-832 is a large fine oven
Scaling forced-convection precision to 512 L requires a 4.5 kW heater and 3-phase power, and adds a manual exhaust damper for quick venting/cooling of a large chamber. The DF designation caps the range at 200 °C; when a process needs 300 °C at this scale, the DH-832 is the direct sibling. (See laboratory-oven-selection.)
Frequently Asked Questions
What temperature range does the Yamato DF-832 reach? Room temperature +15 °C to 200 °C, with ±0.5 °C fluctuation at 200 °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, 13.5 A (Japanese nominal 200 V) — a 3-phase circuit is required.
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.
How is it different from the DH-832? Same 512 L 3-phase fine oven; the DF-832 tops out at 200 °C while the DH-832 reaches 300 °C with a larger 6.9 kW heater.
Ordering & Configuration
quote-based. The DF-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 200 °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 DF-832.
DF/DH 832/1032 large fine-oven range: DF-832 (512 L, 200 °C, this unit) / DF-1032 (1000 L, 200 °C) and DH-832 (512 L, 300 °C) / DH-1032 (1000 L, 300 °C). Pick DF for 200 °C and DH for 300 °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.
