The Yamato DES-830 is a 327 L forced-convection clean oven that maintains Class 100 cleanliness at stable temperature while processing to 260 °C. A heat-resistant HEPA filter (>99.97% at 0.3 µm) and rear-exhaust circulation keep particle counts low, making it the tool for cleanroom-grade drying, curing, and burn-in of electronics, optics, and precision components. It runs on 220V three-phase power; the higher-temperature 360 °C sibling is the DTS830.

Application Profile
A clean oven does what an ordinary oven cannot: it heats and protects the sample from airborne particulate at the same time. The Yamato DES-830 pulls chamber air through a heat-resistant HEPA filter and circulates it with a scirocco fan and rear exhaust, holding Class 100 cleanliness while stable. That combination is essential for semiconductor and electronics manufacturing, optics, medical-device curing, and any process where a dried or cured part must stay contamination-free.
With 327 L of working volume, ±2.0 °C distribution at 260 °C, and a 99-step programmable controller that logs power consumption and CO₂, the DES-830 supports validated, repeatable production cycles. It rides on casters with front levelers for placement, and a built-in differential-pressure meter lets operators watch filter loading. The DES830 can also be converted to a high-performance filter configuration for stable Class 100 up to 200 °C.
Frequently Asked Questions
What cleanliness level does the Yamato DES-830 hold? Class 100 when temperature is stable, using a heat-resistant HEPA filter rated >99.97% at 0.3 µm with forced circulation and rear exhaust.
What temperature range does it cover? Room temperature +30 °C to 260 °C. For processing up to 360 °C, order the DTS830 sibling.
How large is the chamber and how much power does it need? 327 L (620 × 480 × 1100 mm internal); it requires 220V three-phase, 16 A supply and weighs ~335 kg.
How uniform and stable is it? Control accuracy is ±0.5 °C at 260 °C with ±2.0 °C distribution, and it reaches temperature in about 70 minutes.
Can it run automated multi-stage cycles? Yes — the controller stores 99 steps / 99 patterns with repeat, auto start/stop, and data backup.
Ordering & Configuration
Confirm at quote: 220V three-phase supply and breaker, cleanliness/temperature target (DES830 260 °C vs DTS830 360 °C), and options (recorder, N₂ introducer, auto damper).
Warranty: Per Yamato standard capital-equipment terms — confirm coverage at quote.
Because this is a 335 kg, three-phase, caster-mounted instrument, add it to a quote so we can confirm electrical service, siting, delivery access, and lead time.
Yamato DES/DTS clean ovens:
- DES-830 (this product) — 327 L, Class 100, 260 °C, 220V 3-phase
- DTS830 — same 327 L Class 100 chamber, extended to 360 °C (9.0 kW, 24 A)
Choose DES830 for standard clean processing; step to DTS830 only when your cure or bake requires temperatures above 260 °C.
