According to market research on Angola's concrete cooling sector, in hot climates, cooling techniques such as ice cooling and liquid nitrogen help prevent thermal cracking and ensure the desired properties of concrete. However, high equipment costs and limited local technical knowledge pose additional challenges. The client required a concrete cooling system that could operate stably in high-temperature environments with a high degree of automation and rapid deployment capability.

Solution & Core Equipment Configuration

ICESTA designed the following integrated concrete cooling system based on the project's specific requirements:

30T Flake Ice Machine (FID30T)

Produces 30 tons of flake ice per day, utilizing high-efficiency direct evaporation ice-making technology and equipped with international brand compressors to ensure continuous stable operation in Angola's high-temperature environment. Flake ice thickness is adjustable, with a large surface area that enables rapid mixing with concrete and efficient heat absorption through melting.

Fully Automatic Ice Storage & Delivery System

Equipped with an ice rake system and automatic screw conveyor, enabling automated ice storage, uniform distribution, and measured delivery. The storage system features an anti-clumping design to ensure consistent ice availability.

120T Water Chiller

Provides a continuous and stable low-temperature cooling water source for concrete mixing. Through pre-cooling and mixing of chilled water with concrete raw materials, the concrete discharge temperature is controlled from the source.

Containerized Design & Intelligent Control System

The entire system adopts a containerized modular design. All equipment undergoes full pre-assembly and testing at the factory before shipment, requiring only pipe connections and water/power hookup on site. The intelligent touch-screen control system supports fully automatic operation with remote visual monitoring via PC or mobile terminal, enabling 24/7 worry-free operation.

Project Results & Client Value

  • Temperature Compliance: Through the dual cooling method of direct flake ice addition and chilled water pre-cooling, concrete discharge temperature is effectively controlled, meeting ACI 207 standard requirements

  • Rapid Deployment: Containerized design significantly shortens on-site installation time — from equipment arrival to operational status in just days

  • Fully Automated Operation: Ice making, storage, delivery, and chilled water production are fully automated, significantly reducing manual labor dependency

  • Remote O&M: Supports remote control and monitoring via WiFi or network cable, with 24×365 after-sales response and lifelong technical support

  • Strong Environmental Adaptability: Corrosion-resistant design adapts to Angola's coastal and inland complex construction environments; the container structure provides long-term protection for equipment
