Battery Manufacturing EquipmentPouch-cell vacuum tunnel drying furnace
The SUPERCOM pouch-cell vacuum tunnel drying furnace dries cells continuously before electrolyte filling. It lists ultimate vacuum below 5 Pa, leakage below 10 Pa·L/s, contact heating plates with uniformity within ±3 °C and a sealed interior below −40 °C dew point, with CCD positioning at loading and one-button product changeover.

Vacuum, leakage and heating figures
SUPERCOM places this furnace directly before pouch-cell electrolyte filling. It lists ultimate vacuum below 5 Pa and vacuum leakage below 10 Pa·L/s. The first is a pressure endpoint and the second a volumetric leak rate. Final cell moisture is a third figure, measured on the cells themselves.
Contact heating plates use multi-point temperature control, with uniformity given as below ±3 °C. SUPERCOM also describes a sealed interior below −40 °C dew point, handling without fixtures, CCD positioning at loading and one-button product changeover. Ask where each figure is measured, under what load, and which cell sizes the changeover covers.
The page gives no capacity or cycle time. Ask for both with your cell, and assess the drying route together with loading upstream and the handover to filling downstream.
| Parameter | Published value | Record status |
|---|---|---|
| Ultimate vacuum | Below 5 Pa | known |
| Vacuum leakage rate | Below 10 Pa·L/s | known |
| Temperature uniformity | Below ±3 °C; supplier contact-heating specification | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Keep the dried pouch cell dry on its way to filling
Send the cell dimensions, incoming moisture, loading orientation and the final moisture criterion. Agree where cells are sampled after drying and how much exposure is allowed on the way to filling. The −40 °C dew point applies to the sealed interior, so specify the conditions for each transfer step as well.
Ask what the line does when a vacuum or heating cycle is interrupted and how the affected cells are flagged. Have SUPERCOM demonstrate CCD placement and product changeover with your cells, then check the first cells released. Test the data link between the furnace and your plant systems during commissioning.

Keep drying and transfer records for each pouch load
Show the proposed pouch load, the tray or carrier layout and every transfer point on the process drawing. Ask for a separate approved method for vacuum pressure, for leak rate and for temperature uniformity. Each has its own units and test conditions, so each needs its own record.
During a typical drying trial, link the moisture checks and other agreed product tests to the loaded cycle and its transfer history. Mark the atmosphere measuring points through loading and unloading, and write down an approved recovery sequence for an interrupted cycle. Log cells waiting outside the controlled zone apart from cells inside it. Ask the supplier for the handover limits, routine checks and maintenance instructions for the tunnel. Check the atmosphere at every handling step along the load route.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Which vacuum measure is being accepted? | The page lists below 5 Pa ultimate vacuum and below 10 Pa·L/s leakage. | Request the method, loaded conditions and acceptance record for each. |
| Does transfer preserve the required dry environment? | The page gives a −40 °C dew point for the sealed interior. | Map sample paths and check the atmosphere through loading, drying and unloading. |
Equipment questions
Does below 5 Pa mean the cells are dry enough?
Not on its own. That is the ultimate-vacuum figure. Release depends on a loaded trial with moisture measured in your cells.
