How can tens of thousands of tons of mass concrete maintain a stable exit temperature of 7 °C under peak summer heat?

In a construction site with extreme day-night temperature variations, high dust, and continuous vibrations, and under tight schedules with stringent quality requirements, how can a cooling solution remain both efficient and environmentally friendly?

These were the very challenges faced by China Energy Gezhouba Group in a major hydropower hub project. As a key project of century-long significance, concrete temperature control directly impacts structural safety and durability.

Snowman Group delivered an innovative solution.

Through a customized “Aggregate Air Cooling + Ice Water Mixing” integrated system, the Snowman team successfully stabilized the concrete exit temperature below 7 °C, providing a reliable thermal safeguard for the project.

The solution consists of three core systems:

Aggregate Air Cooling System:

Specially designed for high-temperature environments, featuring staged cooling and large circulation centrifugal fans with airflow exceeding 160,000 m³/h, capable of rapidly removing heat from aggregates even under extreme site conditions.

Industrial Ice Plant:

Using Snowman’s patented internal-scraper ice-making technology, the system produces dry ice flakes at high speed. Its industrial-grade design ensures over 15 years of reliable operation, even in dusty and high-vibration environments.

Low-Temperature Chilled Water Station:

Chilled water is precisely mixed with cooled aggregates and ice flakes, achieving strict temperature control for concrete output.

Beyond equipment supply and installation, the Snowman team provided full-cycle technical support, ensuring optimal system performance under varying climatic conditions.

This successful case demonstrates that Snowman Group not only delivers high-quality equipment but also provides systematic, integrated solutions — using technological innovation to safeguard project quality, and “invisible temperatures” to protect the “visible future.”
