Project Name: Renovation of Induction Furnace Cooling System with Closed Cooling Towers in a Thai Foundry
Project Location: Bangkok, Thailand
Equipment Type: 3 sets of Counter-Flow Closed Cooling Towers, each with a single cooling capacity of 500kW
Application Scenario: The project is applied in a Thai foundry that mainly produces auto parts castings and industrial machinery castings, with an annual output of 8,000 tons of castings. The closed cooling towers are used to cool the foundry’s medium-frequency induction furnaces, casting molds and auxiliary electrical equipment.
1. Project Background
Located in Bangkok, the foundry is in an area where the outdoor temperature reaches 34-38°C in summer and the air humidity remains high throughout the year, ranging from 65% to 80%. Originally, the foundry adopted open cooling towers for its cooling system, which had various operational problems. These issues not only seriously undermined the stability of production but also led to an increase in operational costs.
In the production process of a foundry, the stability and efficiency of the cooling system play a direct role in determining product quality, production efficiency and operational costs. The adoption of closed cooling towers in this Thai foundry has not only resolved the key pain points of the original open cooling system—such as unstable cooling performance, high energy consumption, high maintenance costs and severe water pollution—but also achieved the goals of energy conservation, water conservation and environmental protection, thereby bringing significant economic benefits to the enterprise.
This case fully demonstrates that closed cooling towers have excellent adaptability and high application value in the foundry industry, especially under harsh environmental conditions such as high temperature and high humidity. They can provide reliable cooling support for the stable operation of key equipment like induction furnaces.
