The Yamato DH-1032 is the flagship 1000 L large forced-air fine oven with high-accuracy control to 300 °C on 3-phase power — the largest and highest-capacity model in the 832/1032 range. With a 1000 mm cubic chamber, a 9.0 kW heater, and two fan motors, the Yamato DH-1032 delivers production-scale precision heat treatment for the largest parts and batches up to 300 °C. It is the top of the Yamato large fine-oven range.

Application Profile
The 1000 L DH-1032 is the production oven for high-temperature drying, curing, and conditioning of oversized parts or large batches up to 300 °C. Forced air circulation — driven by two fan motors — holds ±1.0 °C fluctuation at 300 °C across the full cubic-meter chamber, with ten shelf positions for dense loading. Glass-wool-plus-ceramic-fiber insulation supports the higher ceiling at scale, and accumulated power/CO₂ monitoring with user setting save/restore suit documented, repeatable production heat treatment.
Why the Yamato DH-1032 is the top of the range
The DH-1032 combines the largest chamber (1000 L), the highest DH ceiling in this series (300 °C), the biggest heater (9.0 kW), and the highest current draw (28 A, 3-phase). Two fan motors maintain uniform convection across the full volume. It is the pick for large-part, high-temperature production; for a 500 °C ceiling in a smaller chamber, the DH-650Z is the alternative. (See laboratory-oven-selection.)
Frequently Asked Questions
What temperature range does the Yamato DH-1032 reach? Room temperature +15 °C to 300 °C, with ±1.0 °C fluctuation at 300 °C.
How large is the chamber? 1000 L — a 1000 × 1000 × 1000 mm cubic chamber with 10 shelf positions at 98 mm pitch.
What power supply does it require? 3-phase AC220V, 28 A (Japanese nominal 200 V) — a dedicated 3-phase circuit is required.
Why does the 1032 have two fans? Uniform forced convection across a full cubic-meter chamber requires two axial-flow fan motors, as noted in the catalog.
How is it different from the DF-1032? Same 1000 L 3-phase fine oven; the DH-1032 reaches 300 °C (vs 200 °C) using a 9.0 kW heater (vs 6.0 kW) and added ceramic-fiber insulation.
Ordering & Configuration
quote-based. The DH-1032 is a capital 3-phase fine oven sold through a quote. At quote we confirm the 3-phase 220 V service and the 28 A circuit, your process temperature and program profile within 300 °C, rigging and floor space for the 1700 × 1215 × 1530 mm, ~450 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-1032.
DF/DH 832/1032 large fine-oven range: DH-1032 (1000 L, 300 °C, this unit) / DH-832 (512 L, 300 °C) and DF-1032 (1000 L, 200 °C) / DF-832 (512 L, 200 °C). Pick DH for 300 °C and DF for 200 °C; pick 1032 for 1000 L and 832 for 512 L. For smaller single-phase chambers use the DF/DH 412/612 series; for 500 °C use the DH-650Z.
