The Yamato DT-611 is the 216 L, 360 °C flagship of the DE/DT high-temperature clean-oven series (brochure model DT610) — a forced-convection clean oven that maintains Class 100 cleanliness during temperature stability via a heat-resistant HEPA filter, with a ceramic-fiber-insulated chamber rated to 360 °C and a 5.2 kW heater under microprocessor PID control. It is the largest, highest-temperature clean oven in the series — the choice for particle-sensitive processes that need both maximum chamber volume and the 360 °C ceiling.

Application Profile
The 216 L DT-611 targets high-throughput, high-temperature, particle-sensitive dry-heat processing to 360 °C. It handles high-temperature clean drying and baking at scale — larger batches that need both a low-particle environment and temperatures above the 260 °C DE ceiling — as well as clean high-temperature curing of advanced coatings and materials where contamination must be minimized. Under Class 100 conditions it supports semiconductor and device processing (high-temperature dehydration and post-process bakes) and contamination-controlled high-temperature conditioning where materials require an elevated thermal soak with clean process air, all governed by programmed thermal profiles of up to 16 segments with slope and repeat.
Ceramic-fiber insulation and a 5.2 kW heater extend the clean-oven concept to 360 °C at the largest chamber volume in the series. (See laboratory-oven-selection.)
Design Architecture
The DT-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 5.2 kW stainless pipe heater and ceramic-fiber insulation for the 360 °C rating. 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. Uniformity at the 360 °C ceiling is ±4.0 °C, reflecting the elevated operating temperature.
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, 16.0 A service (US nominal 220 V) — its 16.0 A draw is the highest in the series; confirm distribution-board capacity.
Frequently Asked Questions
What temperature does the DT-611 reach? Room temperature +30°C up to 360°C, with ±0.3°C temperature stability and ±4.0°C uniformity at the 360°C ceiling. It reaches maximum temperature in about 80 minutes.
What cleanliness level does the DT-611 maintain? Class 100 during temperature stability, achieved with a heat-resistant HEPA filter (>99.97% for 0.3 µm particles) and forced convection from a 400 W sirocco fan.
What power supply does the DT-611 require? AC200V three-phase, 16.0A, 50/60Hz (US nominal 220V) — the highest current draw in the DE/DT series. Confirm your three-phase service and distribution-board capacity.
What is the difference between the DE and DT clean-oven models? DE models use glass-wool insulation and top out at 260°C; DT models use ceramic-fiber insulation for a 360°C ceiling. The DT-611 (brochure model DT610) is the 216 L, 360°C flagship of the series.
Does the DT-611 support programmed thermal profiles? Yes. It offers up to 16-segment program operation with slope and repeat, under microprocessor PID control with a K-thermocouple double sensor.

DE/DT clean-oven series: DE410 (91 L, 260 °C) → DE610 (216 L, 260 °C) → DT410 (91 L, 360 °C) → DT610 (216 L, 360 °C, this unit). 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.
