11 Oct 2025On September 28, DLT's 6th-generation FoaMax three-layer loading foam ceramic tunnel kiln was successfully lighted up at Jianheng Green Materials, Inner Mongolia. The kiln stretches 468.3 meters with an annual production capacity of 110,000 m³ of foam ceramic wall materials, setting a new length record for similar kilns in the industry.
Automated Production System
4.0 3-Layer Loading Tunnel Kiln – breaks industry’s length records of tunnel kiln again
Tunnel Dryer – maximizes kiln waste heat for product drying
Tunnel Cooling Chamber – independent inverter control, pulse-circulation hot air, stepped cooling to slow down cooling speed and reduce cold cracks
