One Unit, Three Zones: NDG1800 at Zhentian (Taiwan)

One Unit, Three Zones with Precision Smart Control.

NDG1800 System Sets Benchmark for Crack and Leakage Prevention in Taiwan’s Municipal Precast Products

[Project Background]

Project: Municipal precast pipe and manhole production line

Equipment: NDG1800 low-pressure steam curing system + full-zone intelligent temperature control, covering 2 curing pools + 1 fixed mold table

Product: Sanitary sewer pipes, trenchless jacking pipes, cement pipes, precast manhole assemblies

Client: Zhentian Co., Ltd. (Taiwan) — established 2003, 20+ years in underground pipeline precast. Automated centrifugal pipe line, in-house concrete lab, full product range certified to Taiwan construction standards. Serves sanitary sewer, stormwater-sewage separation, and trenchless pipe jacking projects.

Why NDG1800 + Full-Zone Intelligent Control ?

01 One unit, three zones: 

Single NDG1800 simultaneously covers 2 curing pools and 1 fixed mold table — perfectly matching the multi-station, differentiated production layout of a modern pipe plant.

02 Smart temperature control eliminates leakage: 

Real-time intelligent system matches curing temperature to pipe and manhole process requirements. Uniform hydration eliminates internal-external temperature differential cracking and surface looseness. Impermeability improved from the source — no more post-installation leakage.

03 Standardized curing, batch-to-batch consistency:  

Fully automatic intelligent curing replaces manual experience-based adjustment. Curing parameters stay uniform across every batch. No more strength inconsistency and quality drift typical of traditional methods.

04 Fully compliant with Taiwan municipal standards: 

Stable curing curves and a uniform temperature field deliver high density and strength pass rates. Cured products meet Taiwan sanitary sewer, stormwater separation, and trenchless pipe jacking acceptance standards.

05 Energy-efficient, low-maintenance:  

Low-pressure direct combustion, on-demand heating — no wasted idling energy. Fully automatic operation minimizes manual intervention. Built for long-term, high-volume production with simple, low-cost maintenance.

Client Feedback

“One unit managing multiple zones — clean layout, stable operation, fits our batch continuous production perfectly.”
“Smart constant-temperature curing significantly improves pipe and manhole consistency, effectively preventing leakage and cracking.”
“High automation, low dependency on manual labor, simple maintenance. Our overall production standardization has improved.”

Results:

NDG1800 turned Zhentian’s multi-zone curing challenge into a single-system, precision-controlled advantage. Zero-leakage pipe quality achieved through standardized intelligent curing. Cleaner surfaces, higher density, stronger impermeability — fully meeting Taiwan’s stringent municipal standards. A benchmark for high-quality underground infrastructure precast.
