The Yamato DE-611 is the 216 L member of the DE/DT high-temperature clean-oven series (brochure model DE610) — a forced-convection clean oven that maintains Class 100 cleanliness during temperature stability via a heat-resistant HEPA filter, rated to 260 °C with microprocessor PID control and program operation. It is the large-capacity 260 °C clean oven, providing more than double the DE-411's chamber volume for higher-throughput particle-sensitive processing.

Application Profile
The 216 L DE-611 targets higher-throughput particle-sensitive dry-heat processing to 260 °C. It handles clean drying and baking at scale — larger batches of electronic, optical, and precision components in a low-particle environment — and clean curing of coatings and adhesives on parts where airborne contamination must be minimized. Under Class 100 conditions it supports semiconductor and device processing (dehydration bakes and post-process drying) and contamination-controlled conditioning where materials require a defined thermal soak with clean process air, all governed by programmed thermal profiles of up to 16 segments with slope and repeat.
The heat-resistant HEPA filter delivers Class 100 cleanliness during temperature stability across the larger 216 L chamber. (See laboratory-oven-selection.)
Design Architecture
The DE-611 uses forced convection driven by a 400 W sirocco fan through a heat-resistant HEPA filter (>99.97% at 0.3 µm), with a 3.6 kW stainless pipe heater and glass-wool insulation. Temperature is governed by microprocessor PID control reading a K-thermocouple double sensor, with a green LED display, 16-segment program operation (slope/repeat), calendar timer, integrating-hours counter (to 49,999 h), and calibration offset. A front analog differential-pressure gauge (0–500 Pa) monitors filter loading, and a manual exhaust damper controls venting; a 32.9 mm cable port is provided at the upper right.
Safety includes an earth-leakage breaker with over-current protection, an independent temperature overheat-prevention device, a door switch, a key-lock function, and self-diagnostics for sensor abnormality, heater disconnection, triac short circuit, and automatic over-rise prevention. This model runs on AC200V three-phase, 11.5 A service (US nominal 220 V).
Frequently Asked Questions
What temperature does the DE-611 reach? It operates from room temperature +30 °C up to 260 °C, with ±0.3 °C stability and ±2.5 °C uniformity at 260 °C, reaching maximum temperature in about 60 minutes.
How clean is the DE-611? It maintains Class 100 cleanliness during temperature stability via a heat-resistant HEPA filter rated >99.97% for 0.3 µm particles.
What is the chamber capacity of the DE-611? The DE-611 (brochure model DE610) has a 216 L chamber with interior dimensions of 600 × 600 × 600 mm.

DE/DT clean-oven series: DE410 (91 L, 260 °C) → DE610 (216 L, 260 °C, this unit) → DT410 (91 L, 360 °C) → DT610 (216 L, 360 °C). DE models use glass-wool insulation to 260 °C; DT models use ceramic-fiber insulation to 360 °C. All are AC200V three-phase Class 100 clean ovens.
