The DKL-611C is the 150-liter, 220V member of Yamato's economical DKL forced-convection family — identical chamber, controller, and performance to the 115V DKL-601C, differing only in electrical supply. It is the largest basic, non-programmable DKL oven, built for high-throughput 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 across the full 150L volume. Ships without a plug (round terminal) for hardwired 220V installation.

Application Profile
The DKL-611C serves the same high-throughput drying and heating workflows as its 115V twin — bulk glassware/labware drying, moisture removal, curing, sterilization prep, and elevated-temperature holds to 260°C — for labs on 220V single-phase power. With 12 shelf steps, the 150L chamber holds many racks or tall vessels per run. Forced convection is essential for even, repeatable heat in a fully loaded large chamber, which natural-convection ovens cannot match.
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 1.5 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-611C 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-611C ship with a power plug? No. As the 220V unit it ships without a plug (round terminal) for hardwired installation. The 115V sibling DKL-601C ships with a plug.
Is the DKL-611C 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? 150 L internal (610 × 500 × 500 mm), with 12 shelf steps at 35 mm pitch; two stainless shelf plates and four brackets are included, each shelf plate rated to 15 kg.
What is the difference between the DKL-601C and DKL-611C? They share the same 150 L chamber, controller, and performance. The DKL-601C is 115V (with plug); the DKL-611C is 220V (no plug, round terminal).
Ordering & Configuration
Ships with the chassis, 2 stainless-steel shelf plates and 4 brackets, and standard ports. The 150L supports the ON61C stand (Q020101002), the OD60C stacking kit (Q010101002), extra shelf sets (Q110101003), 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-601C for 115V); confirm capacity fit (150L vs 90L/411C vs 27L/311C), 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):
- DKL-301C / -311C — 27L
- DKL-401C / -411C — 90L
- DKL-601C / -611C — 150L (this product is the 220V 611C)
For programmable ramp/soak profiles and a color-LCD controller, see the DKV series.
