The DKL-311C is the 27-liter, 220V member of Yamato's economical DKL forced-convection oven family, identical in chamber, controller, and performance to the 115V DKL-301C, differing only in electrical supply. It is the basic, non-programmable benchtop oven for routine drying, curing, and general heating on 220V single-phase service, delivering ±2.5°C temperature-distribution accuracy at 260°C via a 10W Sirocco forced-air fan, the uniformity advantage that distinguishes forced convection from natural/gravity convection. This is the 220V half of the 27L 301C/311C pair; the unit ships without a plug (round terminal) for hardwired 220V installation.

Application Profile
The DKL-311C serves the same routine drying and heating workflows as its 115V twin (glassware and labware drying, moisture removal, coating/adhesive curing, sterilization prep, and general elevated-temperature holds up to 260°C) for labs on 220V single-phase power. The 27L chamber suits single-investigator benches. Forced convection is the right choice over a natural-convection oven wherever even sample-to-sample heat and faster post-door-open recovery matter.
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. An 0.8 kW SUS304 pipe heater under SSR control is governed by PID control from a microprocessor reading a K-thermocouple. Setpoints are entered digitally via menu and ▲/▼ keys; operation modes are Fixed temperature, Quick Auto-Stop, Auto-Stop, and Auto-Start, plus a calibration-offset function. The DKL class has no programmable ramp/soak profiling, for that, step up to the DKV series. Standard ports: one 30 mm I.D. cable port (right side) and two 30 mm I.D. exhaust ports (top).
Safety: self-diagnostic functions (temperature-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 gas atmospheres or with explosive/flammable materials.
Frequently Asked Questions
What temperature range and uniformity does the DKL-311C 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-311C ship with a power plug? No. As the 220V unit it ships without a plug (round terminal) for hardwired installation. The 115V sibling DKL-301C ships with a plug.
Is the DKL-311C 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? 27 L internal (310 × 310 × 310 mm), with 6 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-301C and DKL-311C? They share the same 27 L chamber, controller, and performance. The DKL-301C is 115V (with plug); the DKL-311C is 220V (no plug, round terminal).
Ordering & Configuration
Ships with the oven chassis, 2 stainless-steel shelf plates and 4 brackets, and standard cable/exhaust ports. Optional items include the ON30C stand (Q020101001), extra shelf sets (Q110101001), alternate cable-port diameters (Ø25/Ø50 mm; specify with main-unit order), and a seismic mat (296902).
Confirm at quote: this is the 220V, no-plug/round-terminal unit (choose DKL-301C for 115V with plug); confirm capacity fit (27L vs 90L/411C vs 150L/611C), stand/stacking needs, cable-port diameter, and lead time. Warranty per Yamato standard capital-equipment terms.
