NDG 2400 Low-Pressure Steam Curing System Deployed at Cixi Track Slab Precast Plant

A tight schedule.

19,800 CRTS III high-speed rail track slabs.How do you balance efficiency and cost?

[Project Background]

Location: Cixi Track Slab Precast Plant — Nantong–Suzhou–Jiaxing–Ningbo High-Speed Railway

Equipment: NDG 2400 Low-Pressure Steam Curing System

Supply Mileage: DK217+410 ~ DK271+905, double-track total length 54.966 km (from Hangzhou Bay Cross-Sea Railway south shore → Cixi → Zhuangqiao Station), full section CRTS III ballastless track slabs

Target Opening: Nantong–Suzhou–Jiaxing–Ningbo HSR, end of December 2027

Industry Consensus: Why Are Leading Companies Switching?

This is not an isolated case.
From China Railway and China Communications to Shanghai Tunnel — top domestic precast concrete manufacturers have adopted the same intelligent curing logic across track slab, segment, and box girder applications:

01 

Direct energy consumption 24%+ lower than conventional boilers, with an additional 10%+ in indirect savings

02

Automatic quality control — Pre-set curing recipes and intelligent automation hit temperature curves precisely, removing dependence on veteran operators and eliminating variability.

03

Zero special-equipment burden — Water volume below 30 L means no registration, no annual inspection, and no boiler room; the system deploys directly alongside the line and moves with the project, bringing professional-grade curing even to short-term sites.

04

Proven across precast types — The same logic that cuts costs on temporary track slab jobs, raises efficiency on long-term segment capacity, and safeguards quality on every box girder pour is now the industry’s benchmark for intelligent curing.

The path they have validated repeatedly is itself the most credible endorsement.
NDG is more than a steam generation unit — it is an intelligent curing system built for the future: reducing costs for temporary projects, boosting efficiency for long-term capacity, and safeguarding engineering quality.
Making curing smarter. Making projects easier.
