Concrete Pouring Cooling Ice Water Unit
Unit Introduction
Concrete pouring is crucial during 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 ice water 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; the evaporator and condenser are shell and tube type, with the compressor placed above the evaporator. No water pump is included, requiring an additional water tank and circulation pump.
3. By Evaporator Structure: Closed Ice Water Unit: Refers to a shell and tube evaporator, 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, eliminating concerns of oil leakage. Features safety, reliability, and economy. The company offers one year of free maintenance, lifetime support, and comprehensive after-sales service, earning high praise from customers. Given that large-volume concrete constructions such as highways, high-speed railways, tunnels, hydropower projects, dams, bridges, and hydroelectric power stations often involve thick concrete structures, preventing cracks is essential. Improving project quality requires reducing the heat of hydration and pouring temperature of concrete. Our company has designed a new generation of concrete cooling ice water units through engineering to lower the discharge temperature of concrete, allowing concrete temperature to be reduced below 15°C. In summer, the ambient temperature of cement, stones, and sand is high, and water temperature is also elevated, which is unfavorable for mixing. Therefore, using the concrete cooling ice water unit to directly provide chilled water at 5-10°C, or an ice-water mixture at 0-2°C, can fully meet the process cooling requirements for concrete cooling.
2. The concrete cooling ice water 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 (summer/winter). It features energy efficiency, time-saving, stability, and environmental friendliness. To meet the actual production needs of a wide range of customers, we can design, produce, and provide supporting units according 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 projects, dams, hydroelectric power stations, and civil concrete mixing and cooling. It can control the temperature required for modern industrial mechanized production, improving production efficiency and product quality.
Product Features
1.Temperature Control: -45°C to 30°C ±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, this series of units has the major advantage of not requiring a water cooling system, making it usable wherever there is good ventilation.
4.Beyond standard products, our company can customize various special ice water units and heat pump units according to customer requirements, providing on-site assembly, technical guidance, and commissioning services.
