NDG Low-Pressure Steam System (CureSteam)
Utilizing low-pressure steam technology, the system delivers a stable and uniform steam supply to ensure concrete strength and surface quality. The Siemens PLC-based intelligent control system enables 24/7 unattended operation, real-time monitoring, and full data traceability. The equipment flexibly covers multiple large workshops and supports shared usage across areas to maximize utilization. Proximity control cabinets further enhance safety and production efficiency. Optimized curing profiles reduce steam consumption and carbon footprint while extending equipment life. Precise ramp-rate control prevents thermal shock and cracking, ensuring consistent and reliable quality across all product types.
