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).
