Concrete Pouring Cooling Water Chiller Unit
Unit Introduction
Concrete pouring is crucial in the construction process. The cement hydration reaction releases heat, which can lead to excessively high temperatures. The standard pouring temperature for concrete is between 5°C and 25°C. Excessively high temperatures can cause cracking and other issues, affecting the strength and toughness of the concrete. Cooling measures are necessary, and the concrete cooling water chiller unit is used to control the water temperature. Mixing concrete with water below 10°C can achieve the suitable temperature required for concrete pouring.
Unit Classification
1. By Cooling (Heat Dissipation) Method
A、Water-cooled: (Shell and Tube Type) Condenser equipped with a cooling tower for heat dissipation.
B、Air-cooled: (Finned Type) Condenser dissipates heat through the unit's own fans.
2. By External Structure
A、Enclosed Type: Equipped with an external casing, including a water pump and water tank inside.
B、Open Type: No external casing; evaporator and condenser are shell and tube type, with the compressor placed on top of the evaporator. No water pump is included, requiring an external water tank and circulation pump.
3. By Evaporator Structure: Closed Water Chiller: Refers to an evaporator of shell and tube type, which can have an internal or external water pump, may or may not have an external casing, and the condenser type depends on whether it is air-cooled or water-cooled.
Product Advantages
1. Utilizes semi-hermetic screw compressors with high cooling capacity, integrated motor and compressor,no risk of oil leakage.Features safety, reliability, and economy. The company offers one year of free maintenance,lifetime support.Comprehensive after-sales servicehas earned widespread customer acclaim. Given that large-volume concrete construction is common in projects such as highways, high-speed railways, tunnels, hydropower, dams, bridges, and hydropower stations, it is essential to prevent cracks in thick concrete structures. Improving project quality requires reducing the heat of hydration and pouring temperature of concrete. To this end, our company has designed a new generation of concrete cooling water chiller units through engineering to lower the discharge temperature of concrete, concrete temperature can be reduced to below 15°C. In summer, the ambient temperature of cement, gravel, and sand is high, and water temperature is also high, which is not conducive to mixing. Therefore, using the concrete cooling water chiller unit to directly provide 5-10℃ chilled water, or 0-2℃ ice-water mixture, can fully meet the process cooling requirements for concrete cooling.
2. The concrete cooling water chiller unit uses screw compressors as the main refrigeration component, combined with a fully automatic control system. It can automatically select single-stage or multi-stage cooling based on inlet and outlet water temperatures or seasonal operating modes, featuring energy efficiency, time savings, stability, and environmental friendliness. To meet the actual production needs of a wide range of customers, we can design, produce, and supply units tailored to on-site construction requirements.
Unit Applications
Widely used in large-scale construction projects such as bridges, dams, water resources and hydropower bureaus, including high-speed railways, tunnels, hydropower, dams, hydropower stations, and civil concrete mixing and cooling. It controls the temperature required for modern industrial mechanized production, improving production efficiency and product quality.
Product Features
1.Temperature Control: -45℃ to 30℃ ±1, adjustable temperature
2.Cooling Capacity Range: 102,500 Kcal/h to 654,800 Kcal/h.
3.In addition to the general characteristics of water-cooled screw unit series, the biggest advantage of this series is that it does not require a water cooling system and can be used in any well-ventilated area.
4.Besides standard products, our company can customize various special water chiller units and heat pump units according to customer requirements, providing on-site assembly, technical guidance, and commissioning services.
