The DKL-411C is the 90-liter, 220V member of Yamato's economical DKL forced-convection family — identical chamber, controller, and performance to the 115V DKL-401C, differing only in electrical supply. It is the basic, non-programmable benchtop oven for mid-scale drying, curing, and general heating on 220V single-phase service, with a 10W Sirocco forced-air fan holding ±2.5°C distribution accuracy at 260°C — the uniformity advantage of forced over natural convection. Ships without a plug (round terminal) for hardwired 220V installation.

Application Profile
The DKL-411C serves the same mid-scale drying and heating workflows as its 115V twin — glassware/labware drying, moisture removal, coating and adhesive curing, sterilization prep, and elevated-temperature holds to 260°C — for labs on 220V single-phase power. The 90L chamber with 9 shelf steps handles taller items and multiple racks. Forced convection provides the even, repeatable heat natural-convection ovens cannot match for filled chambers.
Design Architecture
A 10W Sirocco fan circulates air through a stainless-steel (SUS430) chamber inside glass-wool insulation and a powder-coated SPCC steel exterior. A 1.2 kW SUS304 pipe heater under SSR control is governed by PID control from a microprocessor reading a K-thermocouple. Digital setpoints (menu + ▲/▼ keys); operation modes Fixed temperature, Quick Auto-Stop, Auto-Stop, Auto-Start plus calibration offset. No programmable ramp/soak on the DKL class. Standard: one 30 mm I.D. cable port (right) and two 30 mm I.D. exhaust ports (top).
Safety: self-diagnostic functions (sensor error, memory error, automatic overheat prevention, measured-temperature error), an MCB with over-current protector, and an independent hydraulic standalone overheat-prevention device. Never use in flammable/explosive atmospheres or with flammable materials.
Frequently Asked Questions
What temperature range and uniformity does the DKL-411C deliver? Room temperature +10°C to 260°C, with ±1°C control accuracy and ±2.5°C temperature distribution at 260°C, reaching setpoint in about 90 minutes.
Does the DKL-411C ship with a power plug? No. As the 220V unit it ships without a plug (round terminal) for hardwired installation. The 115V sibling DKL-401C ships with a plug.
Is the DKL-411C programmable? No. The DKL class is non-programmable, offering Fixed temperature, Quick Auto-Stop, Auto-Stop, and Auto-Start modes plus a calibration offset. For programmable ramp/soak profiles, choose the DKV series.
How large is it and how many shelves does it hold? 90 L internal (450 × 450 × 450 mm), with 9 shelf steps at 35 mm pitch; two stainless shelf plates and four brackets are included, each rated to 15 kg.
What is the difference between the DKL-401C and DKL-411C? They share the same 90 L chamber, controller, and performance. The DKL-401C is 115V (with plug); the DKL-411C is 220V (no plug, round terminal).
Ordering & Configuration
Ships with the chassis, 2 stainless-steel shelf plates and 4 brackets, and standard ports. The 90L supports the ON61C stand (Q020101002), the OD40C stacking kit (Q010101001), extra shelf sets (Q110101002), alternate cable ports (Ø25/Ø50 mm), and a seismic mat (296902).
Confirm at quote: this is the 220V, no-plug/round-terminal unit (choose DKL-401C for 115V); confirm capacity fit (90L vs 27L/311C vs 150L/611C), stand vs stacking-kit configuration, cable-port diameter, and lead time. Warranty per Yamato standard capital-equipment terms.
DKL forced-convection family (economical, non-programmable):
