The Yamato DKN402C is a programmable forced convection oven delivering precise temperature control and uniform heating for laboratory and industrial drying, heating, and annealing processes. Built with a 90-liter stainless steel interior chamber and 1.2 kW SUS pipe heater, this unit maintains ±1°C control accuracy at 210°C with ±2.5°C temperature distribution uniformity. A 30-step, 3-pattern programmable PID controller stores up to 9 patterns with 18 steps per pattern, supporting fixed temperature, program, auto start, and quick auto-stop modes. Timer functions extend from 1 minute to 999 hours 50 minutes with timer wait capability. The oven reaches 260°C in approximately 90 minutes and operates across ambient +10°C to 260°C. Constructed with powder-coated steel exterior, rock-wool insulation, and a triple chemical-strengthened glass observation window, the DKN402C includes integrated safety features: automatic overheating prevention, self-diagnostic monitoring for temperature sensor faults and heater disconnection, electric leakage breaker, door safety switch, and key lock function. Internal dimensions measure 450 × 450 × 450 mm (17″ × 17″ × 17″), with external footprint 560 × 601 × 820 mm and approximate weight of 50 kg. Exhaust ports (30 mm I.D.) mount on the right side or top. The unit draws 11 amperes at 115 V AC, 50/60 Hz, with resolution of 1°C. Supplied with two shelves, brackets, power cord, and complete operator documentation.
