Battery Manufacturing EquipmentGelon laboratory 25/50 L vacuum drying oven family
Gelon's laboratory vacuum oven comes in 25 L and 50 L chamber sizes and pulls below 133 Pa. It has temperature correction, an over-temperature alarm, a timer, parameter memory and recovery after a power cut, on a 220 V supply under 1500 W. It suits drying powders and electrode samples in battery labs once a drying recipe is proven.
Sizes, vacuum and controls
Gelon lists a standard single-phase 220 V AC, 50/60 Hz supply and power below 1500 W. A trailing 10A Ma entry is cut off, so ask for the current rating on the signed specification. Chamber sizes are 25 and 50 L. Vacuum is printed as below 133 Pa, with no gauge position, pump package, load condition or hold test.
Gelon describes vacuum drying for heat-sensitive materials, powders and granules. In a battery lab it can dry materials and electrode sheets once qualified; ask Gelon before using it with charged cells or flammable solvents. Request the temperature range, chamber dimensions, shelves, pump and the materials it is rated for.

Dry to a measured endpoint
Tell Gelon the material or electrode, the quantity, how it sits on the shelves and the residual moisture or solvent you need. Ask where chamber pressure is measured and how a loaded oven reaches and holds it. A batch gives off vapour, so check the pressure with a real load inside, since no pump-down curve or drying result is published.
Define temperature measuring points, loaded uniformity, dwell and the sampling that proves dryness. The page gives no heating range or precision for this model, so get those figures in writing. Agree solvent compatibility and the exhaust and collection scope before you write the process.

What happens after a power cut
Gelon names temperature correction, an over-temperature alarm, a timer, parameter memory and call recovery. Ask whether call recovery restores the settings only or also restarts heating by itself, and make sure that behaviour suits your material and operator procedure.
During acceptance, trigger the alarm, a sensor fault if covered, and a controlled power cut, following the delivered instructions. Include unloading, cleaning and vacuum system maintenance. Choose between 25 and 50 L on usable load and measured dryness. At handover, keep the loaded recipe and the restart and alarm test results.
Dried electrodes go on to cell assembly, the next category, and the guide to writing an RFQ explains how to request vacuum and temperature records.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Can this oven run the intended material process? | The page lists no temperature range or solvent rating. | Get a signed thermal and material specification before the drying trial. |
| Does <133 Pa apply to the loaded chamber? | The page gives no gauge, pump or test condition. | Measure loaded pressure and the residual moisture or solvent endpoint. |
| What resumes after power loss? | The page names call recovery without describing it. | Agree and witness restart, alarms and operator recovery. |
