Applications of Scroll Chiller in Concrete Batching

Chillers play a vital role in the concrete batching process, and the use of appropriate chillers is essential. Batching plant chillers are designed to cool concrete batching plants to ensure maximum productivity. Concrete batching plants combine cement, water, and aggregates to produce concrete, which is then used for various construction projects. However, the use of the correct scroll chiller is critical to avoid major challenges during concreting in hot and tropical regions.

Batching plant chillers function by circulating chilled water through a heat exchanger, which cools the concrete mixture. The combination of high temperatures and heat generated during the curing process can result in superficial and integral cracks and other defects that affect the durability and safety of the structure. Chilled concrete is crucial for reducing the temperature of the concrete mixture, which helps control the heat generated during the hydration process.

The Problem Factor :

Ineffective use of scroll chillers can disrupt the required temperature, leading to cracks in the concrete. Two main challenges encountered during the concrete batching process are high environmental temperatures and high temperatures of the concrete itself. Additionally, using scroll chillers without proper site monitoring can cause them to break down, disrupting the concrete batching process. Chiller failures can significantly impact the quality and consistency of the concrete. If the chiller fails or malfunctions, the temperature of the water used in the mix can rise, resulting in several potential issues:

1. Reduced workability:
   As the temperature of the water increases, the hydration process accelerates, causing the concrete to set more quickly. This can lead to reduced workability, making it difficult to place and finish the concrete.
2. Reduced strength:
   Rapid hydration can also lead to reduced strength development, as the concrete does not have enough time to develop the necessary strength properties. This can result in a weaker final product that may be more prone to cracking and other durability issues.
3. Thermal cracking:
   The increased temperature of the concrete can also lead to thermal cracking, as the concrete expands and contracts more rapidly than it should. This can result in unsightly cracks on the surface of the concrete, as well as potential structural issues.

Why do chillers Fail?

• Lack of maintenance : 
  Infrequent maintenance is a primary cause of chiller breakdowns. Neglecting certain parts and fixtures can result in significant damage and expenses.
• Oversizing/Undersizing :
  Improper installation of scroll chillers can disrupt the concrete batching process by causing variations in the required temperatures. If the chiller is oversized or undersized, the refrigeration emitted may be too high or too low, resulting in cracks in the concrete.

• Substandard Chillers :
  Using substandard scroll chillers can be risky, as they may not provide accurate temperature control. Inefficiency and ineffectiveness are byproducts of substandard chillers, making the use of standardized chillers essential.

Solution :

Tempcon’s scroll chillers are precisely designed to operate under extreme conditions in concrete batching plants. These smartly engineered chillers can be easily applied in various settings, including high-rise buildings, dam projects, power plants, roads and projects, and precast yards. One of the advantages of using Tempcon’s scroll chiller in a concrete batching plant is its ability to provide accurate temperature control, allowing for precise cooling of the water used in the mix. This is crucial, as even minor temperature variations can significantly impact the quality and consistency of the final product.

In addition to providing accurate temperature control, Tempcon’s scroll chillers are also efficient and cost-effective. They consume less energy than other types of chillers and require less maintenance. Furthermore, they are reliable, with a long lifespan and minimal downtime.
