The DKV-410 is the 90-liter, 220V member of Yamato's programmable DKV forced-convection family, identical chamber, VSD-1 controller, and performance to the 115V DKV-400, differing only in electrical supply. It brings the same 3.5-inch color-LCD programmable control, multi-step program operation, and communication/output terminals to labs on 220V single-phase service, with forced convection delivering ±0.6°C temperature fluctuation and a 9°C gradient (per brochure test conditions). Ships without a plug (round terminal) for hardwired 220V installation.

Application Profile
The DKV-410 serves the same method-driven thermal processing as its 115V twin (multi-step drying/curing profiles, timed ramp-and-hold cycles, timed auto-start runs, and processes needing data output or alarm supervision up to 260°C) for labs on 220V single-phase power. The 90L chamber fits general single-instrument benches. Programmable forced convection is the right choice where both uniformity and repeatable process execution are required.
Design Architecture
Air is driven through a stainless-steel chamber inside a chromium-free electrogalvanized steel, baked-on-finish exterior. A 1.5 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) and two 33 mm I.D. exhaust ports (top) are standard.
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, and an overcurrent leakage breaker. Never use in flammable/explosive atmospheres or with flammable materials.
Frequently Asked Questions
What is the chamber size of the DKV-410? The DKV-410 has a 90 L internal capacity (450 × 450 × 450 mm), fitting general single-instrument benches.
Is the DKV-410 a 115V or 220V oven? The DKV-410 is the 220V, 7.5A member of the DKV family and ships without a plug (round terminal) for hardwired installation. Its 115V twin is the DKV-400.
What temperature range does the DKV-410 reach? It operates from room temp. +10°C to 260°C (the brochure header/test reference cites 270°C; see notes), with forced convection delivering ±0.6°C temperature fluctuation and a 9°C gradient per brochure test conditions.
Is the DKV-410 programmable? Yes. The DKV-410 uses the VSD-1 controller with a 3.5-inch color LCD and supports multi-step program operation, including Auto-Start, Programmed Auto-Start, and ramp/soak profiles.
How is the DKV-410 purchased? As capital equipment, the DKV-410 is quote-based. Confirm the 220V no-plug/round-terminal build, capacity fit, and configuration at quote.
Ordering & Configuration
Ships with the chassis, 1 stainless-steel perforated shelf plate + 2 brackets, and standard ports. Optional items: stand OA117/281355, stacking kit OA196/281598, extra shelf-and-bracket set 212246, sheath sensor ODT48/212946, silicone stopper ODT52/212947, rubber feet OA198/281634, alternate cable ports (281454/281455), and seismic isolation mat 296902.
Confirm at quote: this is the 220V, no-plug/round-terminal unit (choose DKV-400 for 115V); confirm capacity fit (90L vs 150L/610 vs 300L/810 vs 535L/910), stand/stacking configuration, communication/recorder needs, cable-port spec, and lead time. Warranty per Yamato standard capital-equipment terms.
