Client: Processing workshop of a well-known automotive parts manufacturing company in Mexico

Country: Mexico

Equipment Model: Closed Circuit Cooling Tower

Media: Process Water

Quantity: 3 Units

Project Description

closed circuit cooling towers were installed for a well-known industrial manufacturing project in Mexico for precise temperature control of core equipment on the production line. Addressing the local water scarcity and dusty environment, the project adopted a fully closed-loop design, achieving zero-pollution, high-efficiency operation. The overall water-saving effect exceeded the client's expectations, ensuring green and continuous production in the multinational factory.

Recommended Standardized Case Name: Green & Water-Saving Integration: Closed Cooling Tower Project for Mexican Automotive Manufacturing Core Line

Situation

In recent years, Mexico has become a major recipient of global manufacturing relocation, with its automotive and heavy industries developing rapidly. However, many industrial areas in Mexico are located in arid or semi-arid regions, where water resources are subject to high taxes and are in short supply. This client is a leading multinational automotive parts manufacturer in Mexico, whose core quenching and welding lines have extremely stringent requirements for the temperature fluctuation (stable within ±1℃) and purity of the circulating cooling water. Traditional open cooling towers, due to direct contact with the air, are prone to dust inhalation, scaling, and equipment corrosion in the windy and dusty climate of Mexico. Furthermore, their evaporation and drift water consumption are enormous, failing to meet local government environmental compliance requirements for green factories.

Task

The core objective of this project is to build a high-precision, zero-pollution cooling system with extreme water-saving capabilities.

• Extreme Water Quality Protection: It is essential to ensure 100% closed-loop circulation of the cooling medium (water), completely preventing the entry of external windblown sand and impurities to protect the core production line from scaling.

• Stringent Temperature Control and Water-Saving Balance: In the high temperatures of Mexican summers, it is crucial to ensure efficient heat dissipation while minimizing drift water consumption through technological means.

• International Standard Delivery: The equipment design and manufacturing must fully comply with North American and Mexican industrial safety and electrical standards, and be adaptable to long-distance international sea freight and rapid on-site integration and installation.

Standardized Action

The Shandong Casen Heat Transfer Solutions expert team, after multiple rounds of simulations, customized a modular parallel solution for three  closed-loop cooling towers:

• Fully Enclosed Dual-Circulation Design: Utilizing stainless steel heat exchange tube bundles, process water flows within the closed system, completely isolated from the outside environment, eliminating the risk of scaling and pipe blockage at the source.

• High-Efficiency Water-Saving Spray and Water Collection System: Optimized spray density and equipped with Casen's unique high-efficiency PVC water collector, significantly reducing drift and locking in moisture.

• Intelligent Variable Frequency Energy-Saving Control: Introducing an automated control system that dynamically adjusts fan start/stop and spray pump power based on Mexico's large diurnal temperature range, avoiding unnecessary energy and water consumption.

• Heavy-duty corrosion resistance and customized for overseas markets: The outer shell is made of reinforced galvanized steel or stainless steel, possessing superior weather resistance and sandstorm resistance; a full set of pressure tests and pre-assembly are completed before leaving the factory, and all-English installation instructions and remote digital operation and maintenance support are provided.

Key Achievements

closed-loop cooling towers were successfully put into production and are operating at high standards in the Mexican factory:

• Perfect temperature control accuracy: The core heat exchange equipment of the production line achieves scale-free, zero-failure continuous operation, with cooling water temperature stably maintained within the set range, significantly improving product yield.

• Excellent water-saving benefits: Compared with traditional open systems, due to the adoption of closed-loop circulation and efficient water collection technology, the overall water saving rate is over 25%, saving customers nearly US$10,000 in water and sewage costs annually.

• Winning international trust: The equipment's excellent performance in terms of low failure rate and low maintenance costs has won high praise from the Mexican customer's management, setting a benchmark for Kaisen's brand in the Latin American market.

SMART Metrics

• Successfully delivered and connected to the grid for closed-circuit cooling towers

• System scaling rate: 0% (zero damage to the production line)

• Overall water saving rate: >25% (compared to open towers of the same specifications)

• Annual equipment maintenance cost reduction: Approximately 30%

Reusability Takeaways

Fully enclosed, zero-pollution heat exchange technology: Perfectly solves the scaling and corrosion problems of industrial equipment in windy, sandy, and arid regions.

Modular parallel design (3 units in parallel): Allows for flexible start-up and shutdown according to production load, providing extremely high energy efficiency and flexibility, and is easily replicated in similar medium-sized processing workshops.

One-stop delivery compliant with overseas standards: Standardized cross-border fulfillment processes from overseas packaging and international standard certification to digital remote technical support.
