The Yamato DX-612C is the 220 V, 153 L top-capacity model of the DX natural-convection drying-oven family, a constant-temperature gravity-convection oven with a rated maximum operating temperature of 280 °C. Mechanically identical to the 115 V DX-602C, the Yamato DX-612C serves labs on 220 V single-phase service that need the largest DX chamber with fan-free gravity airflow. It is the top of the DX capacity ladder.

Application Profile
The 153 L DX-612C is the DX oven for larger drying batches — trays of glassware, bulk samples, prepared media — and for curing and dry-to-constant-weight preparation below 280 °C. Its natural-convection design moves air without a fan, disturbing light samples and powders less than a forced-convection oven and generating fewer airborne particulates, useful when drying loose or cleanliness-sensitive material at volume.
Why the Yamato DX-612C fits gravity-convection work
The rotating exhaust damper trades uniformity for moisture removal — closed for a stable soak, opened to vent evolved moisture from a full load. Gravity convection accepts a wider distribution band (±10 °C at 280 °C) and slower recovery in exchange for gentle airflow; where tighter uniformity across a large load is required, a forced-convection oven is the better fit. (See the gravity-vs-forced-convection-oven guide.)
Frequently Asked Questions
What temperature range does the Yamato DX-612C reach? Its rated maximum operating temperature is 280 °C, with distribution accuracy of ±10 °C at 280 °C.
How does the DX-612C differ from the DX-602C? Same 153 L oven; the DX-612C is the 220 V version and the DX-602C is the 115 V-nominal (100 V AC) version.
How large is the chamber? 153 L (600 × 510 × 500 mm internal), with two 15 kg-rated shelves.
Is this a forced-air (fan) oven? No. It is a natural-convection (gravity) oven; moisture vents through a rotating exhaust damper.
How long does it take to heat up? Approximately 80 minutes from ambient to 280 °C.
Ordering & Configuration
quote-based. The DX-612C is a capital drying oven sold through a quote. At quote we confirm your 220 V single-phase service and connection, target soak temperature (≤ 280 °C), shelf count and loading, and the 700 × 640 × 830 mm footprint with exhaust routing. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the DX-612C for your drying or curing workflow.
DX natural-convection family (capacity ladder): DX-302C/312C (28 L) → DX-402C/412C (74 L) → DX-602C/612C (153 L, this unit). Choose the DX line for gentle gravity-convection drying; step up to the programmable DVS series for multi-step ramp/soak recipes, or to a forced-convection oven when tighter uniformity across a full load matters.
