Saggar Handling Systems (SHS)

Designed for the automatic circulation of saggars to the accompanying the roller hearth kiln for LFP processing.
The SHS manages the following activities: Delivery from the exit, convey line, un-lid saggar, de-stacking, emptying, cleaning, filling,
ramming, stacking, lid placement on saggar, and delivery of saggar to entry.

Thermal Oxidizers

Each Thermal Oxidizer can service two continuous kilns. The thermal oxidizer receives waste exhaust gas from the kiln where it is exposed to elevated temperature for decomposition and discharged through the exhaust fan.

Automation and Level 2 SCADA Systems

SCADA systems provides the user with access to vital Industry 4.0 features which includes product traceability, detailed process data for continuous process improvements, comprehensive equipment diagnostics, cost analysis, and, inventory and optimal processing management.
