Replacing Traditional Boilers: Warm-air Kilns and Fixed-mold Steam Dual-system Solution Solves Curing Challenges
[Project Background]
Project: Tianjin Ninghe (160-mu prefabricated base)
Equipment: ConCure WE250B warm-air system (4 kilns), NDG600 + NDG1800 containerized steam generators (140+ fixed molds)
Product: Full-range PC components — composite slabs, stairs, wall panels, balconies
Client: Tianjin Hejia Jingong Building Industrial Co., Ltd.
Warm-Air Kiln (CureCast)
This curing system ensures uniform temperature and zero condensation through even air circulation, effectively extending kiln life. It smartly reuses the concrete’s hydration heat with sealed moisture retention, eliminating the need for extra humidification. Intelligent ramp rate control prevents cracking in wall panels and slabs at the source. The enclosed constant-temperature environment is weather-independent, ensuring stable production year-round.

Fixed-Mold Steam (CureSteam)
Equipped with over 140 independent mold controls, the system links multi-capacity generators on demand to provide dedicated curing profiles for each mold with zero energy waste. Its smart start/stop function automatically cuts off gas and water at the target temperature, saving 50% energy compared to traditional boilers. It ensures a stable supply coverage of 250 to 400 meters across multiple workshops and outdoor storage. Additionally, the system features a Siemens multilingual PLC for real-time visual monitoring, enabling fully automatic and unattended operation.
140+ independent mold controls:
Each mold gets its own curing profile. Multi-capacity generators linked on demand. Zero wasted energy.
Smart start/stop:
Auto gas/water cutoff at target temp. Standby until restart. 50% energy savings vs. traditional boilers.
250–400m stable supply:
Multi-workshop, outdoor storage — full coverage.
Visual, unattended:
Siemens multilingual PLC. Real-time monitoring. Fully automatic.
Results:
Combined system = 50% total energy savings. Clean surface, on-spec strength, zero cracking. Client highly satisfied.
