The Yamato DVS-603C is the 162 L programmable model of the DVS natural-convection drying-oven family, a constant-temperature oven with a VS4 program controller and an operating range of ambient +5 °C to 260 °C. The Yamato DVS-603C offers the larger DVS chamber for higher-throughput programmed drying, curing, and conditioning, retaining the same fan-free gravity airflow and multi-step recipe capability. It is the top-capacity unit in the DVS line.

Application Profile
The 162 L DVS-603C targets higher-throughput programmed drying, curing, and conditioning up to 260 °C, larger batches of samples and media on staged drying cycles, multi-step cure schedules for coatings and adhesives, and standardized conditioning protocols. The reinforced-glass observation window lets operators check a full load without opening the door and disturbing the setpoint.
Why the Yamato DVS-603C fits programmable gravity work
Program operation is the differentiator: the VS4 controller runs multi-segment ramp/soak recipes with quick auto-stop, auto-stop, and auto-start modes for repeatable, hands-off cycles. As a natural-convection oven it moves air gently through a rotating exhaust damper, ±5 °C distribution at 260 °C, tighter than the fixed DX ovens, while staying fan-free. Where forced-air uniformity is essential, step to the DKN/DF forced-convection lines. (See oven-temperature-uniformity.)
Frequently Asked Questions
What temperature range does the Yamato DVS-603C reach? Ambient +5 °C to 260 °C, with ±1 °C control accuracy and ±5 °C distribution accuracy at 260 °C.
How large is the chamber? 162 L (600 × 540 × 500 mm internal), with two 15 kg-rated trays and a 250 × 280 mm reinforced-glass observation window.
Is the DVS-603C programmable? Yes. It uses a VS4 program controller with multi-step program operation plus fixed-temperature, quick auto-stop, auto-stop, and auto-start modes.
Is it forced-air or natural convection? It is a natural-convection oven with a rotating exhaust damper; there is no circulation fan.
What voltage does it use? The DVS602 base model is rated 100V AC, 14 A (US nominal 115 V). The 220 V sibling is the DVS-613C.
Ordering & Configuration
quote-based. The DVS-603C is a capital programmable drying oven sold through a quote. At quote we confirm bench/floor service and plug configuration (this 115 V-nominal unit maps to the brochure's 100 V / 14 A rating), the program profile you need (target soak temperatures and ramp/soak steps ≤ 260 °C), tray loading, and the 710 × 651 × 870 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 DVS-603C.
DVS programmable natural-convection family: DVS-403C/413C (99 L) → DVS-603C/613C (162 L, this unit). Choose the DVS line over the fixed-mode DX ovens when you need automated ramp/soak recipes; step to a forced-convection oven when tight uniformity across a full load is the priority.
