Spécification & support

Ce que demandent habituellement les ingénieurs et les achats

Si la réponse dépend d'un dessin ou d'un numéro de série, écrivez aux ventes avec le modèle. Les fiches techniques et les manuels proviennent de Ressources techniques.

Quand dois-je spécifier une armoire sèche au lieu d'une armoire à azote?

A dry cabinet removes water vapour and holds a low relative humidity — typically down to 1% RH — without a continuous nitrogen supply. Specify it when moisture is the failure mode: MSDs, ICs, PCBs and many process materials. A nitrogen cabinet displaces cabin air so oxygen and moisture fall together. Use N₂ where oxidation is the risk: wafers, silver finishes, copper leadframes and optical coatings.

Une armoire sèche peut-elle atteindre 1% HR sans azote végétal?

Yes. EJER dry cabinets use a closed-loop desiccant system. Ultra-low humidity is a humidity-control job, not a gas-purge job. Nitrogen is reserved for atmospheres where oxygen itself must be displaced.

Quel point de consigne d'humidité est typique pour les appareils sensibles à l'humidité?

Many SMT and semiconductor lines hold 1% RH or 5% RH so MSD floor life can be paused between kitting and placement. The exact window should follow your component MSL, the handling standard you work to (commonly IPC/JEDEC J-STD-033) and the time the parts spend outside the cabinet. We specify the climate to the process, not a single catalogue default.

Quand un four de séchage est-il le bon outil?

When the process needs a documented temperature profile — PCB baking, MSD floor-life reset, or laboratory drying — not only dehumidified air. A dry cabinet stores. An oven dries. Mixing the two jobs usually means the wrong tool for both.

La taille, les portes, la finition et le contrôle peuvent-ils être personnalisés?

Yes. Capacity class, door layout, ESD black, white or stainless finishes, casters, leveling feet and controller options can follow the line, the cleanroom or the bench. Send the climate target, the parts to be stored and any utility constraints; engineering will answer with a configuration, not a generic height.

EJER CLOUD est-il nécessaire sur chaque armoire?
```html

Cloud connection is optional. Where it is specified, cabinets and sensors can report humidity, temperature, energy use and status to the web, desktop, app or mini-program layer, with alarms and electronic records. Discuss it with a new line or a retrofit if you need one view of many units.

Quels certificats et brevets l'approvisionnement devrait-il demander?

Cabinets are manufactured under ISO practice and shipped with CE and RoHS conformity. Intellectual property includes Chinese invention and utility-model patents, plus patents in Germany and the United Kingdom. Named copies can be issued against a model or an order from the Technical resources page.

Comment puis-je demander une fiche technique, un manuel ou un schéma de câblage?

Write to sales with the model (for example D1440-6 or N1440-6), the document you need and the language. Files are issued for a specified unit or project rather than posted as an open download. Use the Technical resources page for the full list of document types.
