When do I need a drying oven instead of a cabinet?

A cabinet holds a stable, low-humidity environment for storage. An oven actively drives moisture out of a load with heat — it is for bake-out, curing, drying reagents and accelerated moisture removal, not for keeping parts dry afterwards. The YSHG range is forced-air convection with PID control, from 30 L bench units to 960 L floor models, with a timer from 1 to 9999 minutes. Temperature uniformity is within ±2.5% measured at 100 °C, fluctuation ±1.0 °C and resolution 0.1 °C. Most production lines end up with both: an oven to dry the incoming load, and a cabinet to keep it dry until use.
