The DKV-810 is the 300-liter, single-phase 220V floor-standing large-capacity oven in Yamato's programmable DKV forced-convection family — the same VSD-1 / 3.5-inch color-LCD programmable control as the benchtop DKVs, scaled to a tall 1000 mm-high chamber for bulk and large-labware thermal processing. Forced convection holds ±0.6°C fluctuation with an 11°C gradient (per brochure test conditions) across the enlarged volume — the uniformity that makes forced convection essential over natural/gravity convection at this scale. This is a 220V single-phase-only model with no 115V variant, and the first Tier-1 unit in the family.

Application Profile
The DKV-810 suits bulk and large-labware thermal processing — high-volume drying, batch curing, multi-rack conditioning, and programmed ramp-and-hold cycles at production or shared-facility scale up to 260°C. The tall 1000 mm chamber with 29 shelf steps and ~120 kg total load supports many racks or tall vessels in one programmed run. Programmable forced convection at this capacity is the right choice for facilities needing both uniformity and repeatable, supervised process execution on large batches.
Design Architecture
Air is driven through a 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 are on the back (not top) on this large model.
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 (standard on the 810/910 floor units). Never use in flammable/explosive atmospheres or with flammable materials.
Frequently Asked Questions
What temperature range does the DKV-810 reach? Room temperature +10°C up to 260°C (the brochure header/test reference cites 270°C — see notes), holding ±0.6°C fluctuation with an 11°C gradient per brochure test conditions.
Is a 115V version of the DKV-810 available? No. At 300 L the DKV-810 is single-phase 220V only (12A, 50/60Hz, no plug, round terminal); there is no 115V variant in this size.
Where are the exhaust ports located? On this large model the two 33 mm I.D. exhaust ports are on the back (not on the top), with one 33 mm I.D. cable port on the right.
Does the DKV-810 come with shelves? Yes — it ships with 3 stainless-steel perforated shelf plates and 6 brackets, across 29 shelf steps at 30 mm pitch. An extra shelf-and-bracket set (212266) is optional.
How is the DKV-810 controlled? By 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 program operation modes.
Ordering & Configuration
As a floor-standing unit the DKV-810 ships with 3 stainless-steel perforated shelf plates + 6 brackets, fall-prevention fittings, and standard cable/rear-exhaust ports (no separate stand needed). Optional items: extra shelf-and-bracket set 212266, sheath sensor ODT48/212946, silicone stopper ODT52/212947, and alternate cable ports (281454/281455).
Confirm at quote: single-phase 220V, 12A supply and hardwired round-terminal connection (there is no 115V option at 300L); floor space and the 1610 mm external height; fall-prevention anchoring; capacity fit (300L vs 150L/610 vs 535L/910); communication/recorder needs; cable-port spec; delivery/rigging; and lead time. Warranty per Yamato standard capital-equipment terms.
