Name: Three-door Vacuum Electrode Drying Oven
Brand: LM Instruments
SKU: LM-ZKKX-3

This unit is designed for vacuum baking of battery electrodes and uninfused cells in lithium battery production.

Principle: Circulating hot air + double-layer thermal insulation; exterior temperature <45°C (excluding glass door).
Heating: O-type external air circulation with left-right convection for uniform heating.
Equipped with high-vacuum pneumatic flapper valves and three independent temperature control zones.
Touchscreen & fully automatic cycle; auto vacuum pressure hold at process end, real-time safety temperature display.
Flexible double-layer glass door, three-level pressure detection and overpressure protection.
Multi-stage overtemperature protection ensures precise temperature control against thermal runaway.
PLC integrated control with touchscreen operation for stable performance.
Corrosion-resistant vacuum tubes + interlock programs prevent inter-layer gas cross-flow.
