The Yamato DTS-830 is a 327 L forced-convection Class 100 clean oven rated to 360 °C, built for particle-controlled high-temperature processing of electronics, optics, semiconductor, and precision-component workloads. The Yamato DTS-830 circulates air through a heat-resistant HEPA filter (>99.97 % collection at 0.3 µm) with rear exhaust, holding Class 100 cleanliness when temperature is stable while a 99-step / 99-pattern programmable controller drives repeatable heat profiles. It is the 360 °C member of the DES/DTS clean-oven pair; the 260 °C sibling is the DES830.

Application Profile
A clean oven exists to do what a standard process oven cannot: heat parts to high temperature without adding particulate contamination. The DTS-830 pulls chamber air through a heat-resistant HEPA filter and returns it via forced scirocco circulation with rear exhaust, so as the chamber stabilizes it reaches and holds Class 100 — fewer than 100 particles ≥0.5 µm per cubic foot. That makes it the correct tool for curing, baking, degassing, and burn-in of components where a single settled particle is a defect: semiconductor and MEMS parts, optics and display glass, precision-machined and coated assemblies, and medical-device substrates.
The 360 °C ceiling and tight ±0.5 °C control distinguish the DTS-830 from its DES830 sibling, which tops out at 260 °C; distribution widens to ±5.0 °C at the 360 °C extreme, which is the expected trade for the extra temperature headroom (see oven-temperature-uniformity). The 99-step, 99-pattern programmable controller lets process engineers lock in multi-stage ramp/soak recipes with repeat cycling, and the control panel additionally reports accumulated power, CO₂, and heater output for facility energy tracking. Because it is a floor-standing, ~335 kg, three-phase instrument, site power and clearance are part of the selection conversation (see laboratory-oven-selection).
Frequently Asked Questions
What cleanliness level does the DTS-830 maintain? Class 100 when the chamber temperature is stable, using a heat-resistant HEPA filter rated >99.97 % collection efficiency at 0.3 µm.
What is the maximum temperature? Room temperature +30 °C to 360 °C, with ±0.5 °C control accuracy at 360 °C. The DES830 sibling is the 260 °C version.
How does the DTS-830 differ from the DES830? Same 327 L Class 100 clean-oven platform, but the DTS-830 reaches 360 °C (9.0 kW heater, 40 A earth-leakage breaker, 24 A supply) versus the DES830's 260 °C (6.0 kW). The DES830 also offers a convertible high-performance filter option maintaining Class 100 up to 200 °C.
What power supply does it require? AC220V, three-phase, 24 A, 50/60 Hz, supplied with no plug and round terminals for hard-wiring by a qualified electrician.
Can it run automated temperature profiles? Yes — up to 99 steps across 99 patterns with a repeat function, plus fixed-temperature operation with auto start/stop and timer or clock control.
Ordering & Configuration
quote-based. The DTS-830 is a floor-standing, three-phase capital clean oven configured to your process. At quote we confirm 220 V three-phase service and hard-wiring, floor space and clearance for the 850 × 1080 × 1955 mm, ~335 kg cabinet, shelf count and any factory-installed options (recorder, manual/auto damper, N₂ introducer, emergency switch, output terminals). Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to specify the DTS-830 for your cleanroom or process line.
DES/DTS clean oven, by temperature: DTS-830 (this unit) reaches 360 °C for the most demanding high-temperature clean processing; the DES830 tops out at 260 °C and offers a convertible Class 100 filter to 200 °C. Both are 327 L, forced-convection, HEPA-filtered Class 100 ovens. Choose the DTS-830 when your bake, cure, or burn-in recipe needs headroom above 260 °C.
