Concrete Cooling Chiller for Pouring

Concrete Pouring Cooling Chiller

Unit Introduction

Concrete pouring is crucial during the construction process. The hydration reaction of cement 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 a concrete cooling chiller 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: Features an external casing with an internal water pump and water tank.

B、Open Type: No external casing; evaporator and condenser are shell and tube type; compressor is placed above the evaporator; no water pump, requires an external water tank and circulation pump.

3. By Evaporator Structure: Closed Chiller: Refers to an evaporator of shell and tube type, which can house a water pump internally or externally, may have a casing or not; 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 oil leakage concerns.Features safety, reliability, and economy. The company offers one year of free maintenance,lifetime support.Comprehensive after-sales service,earning widespread customer acclaim. Given that large-scale concrete constructions such as highways, high-speed rails, tunnels, hydropower projects, dams, bridges, and hydroelectric power stations often involve massive volumes, ensuring no cracks in thick concrete structures is critical. Enhancing project quality requires reducing the heat of hydration and pouring temperature of concrete. Therefore, our company has designed a new generation of concrete cooling chillers 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, stones, and sand is high, and water temperature is also elevated, which is not conducive to mixing. Thus, using a concrete cooling chiller to directly provide chilled water at 5-10℃, or an ice-water mixture at 0-2℃, can fully meet the process cooling requirements for concrete cooling.

2. The concrete cooling chiller uses screw compressors as the main refrigeration unit, 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 as much as possible, 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 rails, tunnels, hydropower projects, dams, hydroelectric power stations, and civil concrete mixing and cooling. It controls the temperature required for modern industrial mechanized production, enhancing 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 chillers and heat pump units according to customer requirements, and provide on-site assembly, technical guidance, and commissioning services.
