Luoyang Judian Metal Hot Processing Equipment Co., LTD is mainly engaged in the manufacture of complete sets of equipment in the metal thermal processing industry and the integration of the entire production line.
This traditional method relies on direct air-water contact to lower water temperature, with cooled water collected in a pool.
Advantages:
Simple design and relatively low initial investment
Easy to install and operate
Limitations:
Requires a large footprint for the pool and plant layout
Evaporation increases impurity concentration, promoting algae and bacteria growth
Scaling and pipe blockages are common, increasing maintenance needs
Long-term reliability may be compromised
This setup is suitable for facilities with limited budgets but may lead to higher operational challenges over time.
2. Open Cooling Tower + Plate Heat Exchanger + Pool
In this design, the water circuit is divided: the internal loop circulates through the furnace and a plate heat exchanger, while the external loop dissipates heat to the atmosphere.
Advantages:
Reduces scaling and algae in the internal loop
Provides better protection for critical furnace components
Limitations:
Higher installation costs and larger space requirements
Dual circulation pumps increase energy consumption
External loop still faces scaling, corrosion, and blockages
This approach offers a balance between efficiency and maintenance, suitable for mid-to-large scale operations.
3. Closed Cooling Tower
The closed cooling tower circulates water through a sealed tube bundle, completely isolated from external contaminants.
Advantages:
Internal water remains free from scaling, evaporation, or algae
Protects the furnace power supply and copper coils
Minimizes water consumption and reduces maintenance
Enhances long-term operational stability
Limitations:
Higher initial investment
Operators require professional training to manage the system
Currently, the closed cooling tower is the most effective choice for industrial electric furnaces, providing reliable performance, equipment protection, and efficient water use.
Selecting the Right Water Circulation System
Choosing the best system depends on:
Plant layout and available space
Budget and energy efficiency goals
Maintenance capabilities and operator expertise
Investing in the proper water cooling configuration ensures long-term reliability, reduced downtime, and optimized furnace performance.
