Battery Manufacturing EquipmentCL-PF30 wound-cell preheating furnace
The KUICHUANG CL-PF30 preheats wound cell cores by placing them on hot plates in drawers. It lists 85±5 °C, a ±0.5 °C adjustment precision and at least 28 PPM. Peak power exceeds 160 kW and weight exceeds 15 tonnes, so site preparation is a major part of the order.

How the CL-PF30 heats and what it lists
KUICHUANG's page says wound cores sit directly on a hot plate and are preheated by conduction, in drawer-style contact heaters. It gives a preheating temperature of 85±5 °C, a higher-temperature entry of up to 110 °C and a temperature-adjustment precision of ±0.5 °C. The adjustment precision describes the controller; core-temperature uniformity and any moisture endpoint need their own measurements.
The page also lists at least 28 PPM, peak power of more than 160 kW, weight of more than 15 tonnes and dimensions of 8,650 × 4,500 × 4,200 mm. Power and weight are given as minimums, so ask KUICHUANG for the exact electrical rating and mass of your configuration, along with the rate on your cores.
| Parameter | Published value | Record status |
|---|---|---|
| Preheating temperature | 85±5 °C | known |
| Temperature adjustment precision | ±0.5 °C | known |
| Heating method | Drawer contact heating for wound cell cores | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Site preparation and loaded temperature
Send the core dimensions, load arrangement, contact surface and the heating endpoint you need. Ask how temperature is measured inside the cores and across loaded positions. Relate the quoted pace to dwell time, handling and the time until the first core reaches the endpoint.
Check floor loading, power supply, access and drawer travel before planning the installation. Ask for protection and recovery steps for interrupted heating. The CL-PF30 is a preheater; vacuum drying and final moisture targets belong to other equipment.

Heating trial and installation as two workstreams
Ask for dimensioned drawings of the machine and its loading, showing how cores contact the plates and the access needed for handling. Get the utility load and support requirements of your configuration for your site engineers to check. The published power and weight figures help with early planning; your building and supply still need an engineering check.
For the heating trial, agree a representative load, the sensor positions and how core temperature will be judged. Log heat-up, holding conditions and loaded uniformity apart from the setpoint and display resolution. Include an approved interruption and unloading sequence in the handover. Ask for operating and maintenance documents for the actual configuration. Together these make a thermal and installation acceptance plan for the furnace.

The SME list and the furnace trial
The 2021 Jiangsu proposed list matches the Kuichuang company name exactly. Temperature uniformity and an accepted cell load come from a trial on the furnace itself. Ask for one with your wound-cell arrangement, logged measurement points and the agreed soak endpoint. Define unloading and transfer downstream as separate items, and price any gauges from Kuichuang's other product lines separately.
Preheated cores usually go on to hot pressing and then into the case, part of the cell assembly sequence; the winding throughput page covers the step before preheating.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What thermal result is required? | The page gives 85±5 °C as the target and ±0.5 °C as adjustment precision. | Agree loaded measurement positions and heat-up and uniformity checks. |
| Can the building support the installation? | The page lists more than 160 kW peak power and more than 15 tonnes. | Ask for the utility load, equipment drawing and floor and support requirements. |
Equipment questions
Is ±0.5 °C the core-temperature uniformity?
No. KUICHUANG calls it temperature-adjustment precision. Ask for a loaded measurement plan and separate results for temperature spread across the cores.
Source s2Can this be specified as a vacuum dryer?
No. The page describes contact preheating, with no vacuum operation or moisture endpoint. Specify vacuum drying as a separate machine.
