The DKV-910 is the 535-liter, single-phase 220V flagship of Yamato's programmable DKV forced-convection family — the largest, highest-capacity oven in the line, a wide twin-column floor unit for the biggest bulk-drying and batch-processing workloads. It carries the same VSD-1 / 3.5-inch color-LCD programmable control and full communication/output suite as the rest of the family, with forced convection holding ±0.6°C fluctuation and an 11°C gradient (per brochure test conditions) across its very large chamber. Unlike the smaller DKVs, the 910 has a lower 220°C maximum operating temperature. This is a 220V single-phase-only Tier-1 model.

Application Profile
The DKV-910 is built for the largest-scale bulk thermal processing — high-volume production drying, large batch curing, and multi-rack conditioning across a twin-column chamber, with programmed ramp-and-hold cycles up to 220°C. The wide 1090 mm interior with two columns of 29 shelf steps and ~120 kg total load supports very large batches or many racks in a single supervised run — the right pick for production lines and core facilities needing maximum capacity with programmable, documented process control. Where a process needs the full 260°C ceiling, choose the 300L DKV-810 instead — the 910 tops out at 220°C.
Design Architecture
Air is driven through a wide stainless-steel chamber inside a chromium-free electrogalvanized steel, baked-on-finish exterior. A 3.0 kW SUS tube heater is governed by PID control from a microcomputer via the VSD-1 controller with a 3.5-inch color LCD, reading a K-thermocouple. Operation modes: Fixed temperature, Quick Auto-Stop, Auto-Stop, Auto-Start, Programmed Auto-Start, and Program operation; timer 1 min to 99 h 59 min. Additional functions: calibration offset, power-failure return mode, timer-wait, security management, upper/lower temperature-limit alarms, fan-OFF delay, program preview, operation-trend display. Terminals: RS-485, 4–20 mA temperature output, time-up output, error output, recorder terminal. Door hinges click at 30° and 120°. One 33 mm I.D. cable port (right); two 33 mm I.D. exhaust ports on the back. The standard 910 includes a center column dividing the twin-column interior; a special-order version without the center column is available (with a limited maximum temperature).
Safety: extensive self-diagnostics (automatic over-temperature protection, sensor error, SSR short, heater disconnection, fan error, clock/relay/memory/comm errors), an independent overheat-prevention device, door switch/door alarm, an overcurrent leakage breaker, and fall-prevention fittings (4 pcs; fixing-hole Φ14, M12 anchors recommended). Never use in flammable/explosive atmospheres or with flammable materials.
Frequently Asked Questions
How large is the DKV-910? 535 L — the flagship, highest-capacity model in the programmable DKV forced-convection family, built as a wide twin-column floor unit. (The brochure header and manifest state 535 L while the spec-table row shows 545 L; confirm the exact figure with Yamato.)
What is its maximum operating temperature? Room temperature +10 °C to 220 °C — a lower maximum than the smaller DKV models (which reach 260/270 °C). Where the full 260 °C ceiling is needed, choose the 300L DKV-810 instead.
How uniform is the temperature? ±0.6 °C fluctuation with an 11 °C gradient at 220 °C, per brochure test conditions, held by forced convection across the large chamber.
What controller does it use? The VSD-1 controller with a 3.5-inch color LCD, offering fixed-temperature, quick auto-stop, auto-stop, auto-start, programmed auto-start, and full program operation, plus RS-485 and 4–20 mA outputs.
What electrical supply does it require? Single-phase 220V, 14.5A, 50/60 Hz, with no plug (round terminal) — a hardwired connection, with no 115V option.
Ordering & Configuration
As a large floor-standing unit the DKV-910 ships with 6 stainless-steel perforated shelf plates + 12 brackets, 4 fall-prevention fittings, the center column, and standard cable/rear-exhaust ports. Optional items: extra shelf-and-bracket set 212490, sheath sensor ODT48/212946, silicone stopper ODT52/212947, and alternate cable ports (281454/281455).
Confirm at quote: single-phase 220V, 14.5A hardwired round-terminal supply (no 115V option); that the 220°C maximum (lower than the rest of the family) suits the process; the 535L vs 545L brochure capacity discrepancy (confirm exact figure with Yamato); floor space and the 1220 × 685 × 1610 mm / ~195 kg footprint; M12 fall-prevention anchoring; whether the center-column-delete special order is needed; communication/recorder needs; cable-port spec; delivery/rigging; and lead time. Warranty per Yamato standard capital-equipment terms.
