متى يجب تحديد خزانة جافة بدلاً من خزانة النيتروجين ؟

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.

هل يمكن لخزانة جافة أن تصل إلى 1 ٪ RH بدون نيتروجين نباتي ؟

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.

ما هي نقطة ضبط الرطوبة النموذجية للأجهزة الحساسة للرطوبة ؟

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.

متى يكون فرن التجفيف الأداة المناسبة ؟
When the process needs a documented temperature profile — PCB baking, MSD floor-life reset, or laboratory drying — not only dehumidified air is required, but also a suitable drying cabinet. An oven alone does not fulfill both roles effectively. Mixing these tasks typically involves using the wrong tool for both purposes.

For instance, while an oven might provide the necessary heat and airflow for drying samples, it won't offer the controlled humidity levels needed for other processes. Similarly, a drying cabinet won’t supply the high temperatures required for certain applications.

Therefore, when combining these functions, ensure that each stage uses the appropriate equipment to maintain optimal conditions and achieve desired results.

هل يمكن تخصيص الحجم والأبواب والانتهاء والتحكم ؟

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.

هل سحابة EJER مطلوبة في كل خزانة ؟

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.

ما الشهادات وبراءات الاختراع التي يجب أن تطلبها المشتريات ؟

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.

كيف يمكنني طلب ورقة بيانات أو دليل أو رسم بياني للأسلاك ؟

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.
