The DKL-301C is the 27-liter, 115V entry point of Yamato's economical DKL forced-convection oven family — a basic, non-programmable benchtop oven built for routine drying, curing, and general-purpose heating where a fixed setpoint and reliable air circulation are all the workflow needs. A 10W Sirocco (forced-air) fan drives active convection across the chamber, delivering ±2.5°C temperature-distribution accuracy at 260°C — substantially tighter uniformity than a gravity/natural-convection oven of the same class, which is the reason to reach for forced convection when sample-to-sample consistency matters. This is the smallest of three capacities (27L / 90L / 150L) and the 115V half of the 301C/311C pair.

Application Profile
The DKL-301C suits routine laboratory drying and heating where a stable fixed temperature is the whole job: drying glassware and labware, moisture removal, curing coatings and adhesives, sterilization prep, sample conditioning, and general elevated-temperature holds up to 260°C. The compact 27L chamber fits crowded benches and single-investigator workflows. Forced convection makes it the right pick over a natural-convection oven when you need even heat across multiple samples or faster recovery after door openings.
Design Architecture
Air is circulated by a 10W Sirocco fan through a chamber lined in stainless steel (SUS430), wrapped in glass-wool insulation behind a powder-coated SPCC steel exterior. Heat comes from an 0.8 kW SUS304 pipe heater under SSR (solid-state relay) control, governed by PID control from a microprocessor reading a K-thermocouple. Temperature is set digitally with dedicated menu keys and ▲/▼ keys. Operation modes are Fixed temperature, Quick Auto-Stop, Auto-Stop, and Auto-Start, with a calibration-offset auxiliary function. There is no programmable ramp/soak profiling on the DKL class — for programmable multi-step profiles and a color-LCD controller, the DKV series is the step up. A 30 mm I.D. cable port (right side) and two 30 mm I.D. exhaust ports (top) are standard.
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. Per the brochure: never use in flammable or explosive gas atmospheres, and never process explosive or flammable materials.
Frequently Asked Questions
What temperature range does the DKL-301C reach? The DKL-301C operates from room temperature +10°C up to 260°C, with ±1°C control accuracy and ±2.5°C temperature-distribution accuracy at 260°C.
Is the DKL-301C available in 220V? No — this is the 115V unit (AC115V, 7.5A, 50/60Hz, with plug). The 220V sister model is the DKL-311C.
Does the DKL-301C support programmable temperature profiles? No. The DKL class is non-programmable, offering fixed-temperature, quick auto-stop, auto-stop, and auto-start modes only. For programmable ramp/soak profiles and a color-LCD controller, step up to the DKV series.
Why choose the forced-convection DKL-301C over a gravity/natural-convection oven? A 10W Sirocco forced-air fan actively circulates air across the chamber, delivering ±2.5°C distribution accuracy at 260°C — tighter uniformity than a same-class gravity oven, which matters when sample-to-sample consistency and faster recovery after door openings are needed.
Does the DKL-301C come with shelves? Yes. It ships with 2 stainless-steel shelf plates and 4 shelf brackets, with 6 shelf steps at 35 mm pitch and a 15 kg load rating per shelf plate. Additional shelf sets are available as options.
Ordering & Configuration
Ships with the oven chassis, 2 stainless-steel shelf plates and 4 shelf brackets, and the standard cable/exhaust ports. Optional items (ordered separately) include the ON30C stand (Q020101001), additional shelf sets (Q110101001), alternate cable-port diameters (Ø25 mm / Ø50 mm — specify with main-unit order), and a seismic mat (296902).
Confirm at quote: voltage/plug configuration (this is the 115V unit; choose DKL-311C for 220V), capacity fit (27L vs 90L/411C vs 150L/611C), stand or stacking-kit needs, cable-port diameter, and lead time. Warranty per Yamato standard capital-equipment terms — confirm at quote.
