The Challenge: Heat Exchanger Fouling
Fouling on heat transfer surfaces decreases performance and productivity. It is extremely costly for industries and power plants constantly seeking methods to eliminate deposits online.
In water-cooled air conditioning systems, impurities in the cooling water circuit accumulate, building up scales and deposits in condenser tubes. This fouling increases chiller energy consumption. The Automatic Tube Cleaning System circulating soft sponge balls through the tubes at pre-set intervals to maintain peak efficiency without damaging the tube surfaces.
Working Procedures
Cleaning balls are introduced via a ball collector partitioned by a screen. When deaerated, these balls have nearly the same specific gravity as cooling water, allowing them to follow the same flow path into the heat exchanger. Once they pass through the tubes, they are intercepted by a strainer and conveyed by a special pump back through the collector to the injection site.
Protection: Eliminates abnormal pressure and prolongs compressor lifespan.
Eco-Friendly: Physical processing reduces chemical treatment costs.

Frequently Asked Questions
1. How does the automatic tube cleaning system save energy?
By preventing the buildup of scales and deposits on condenser heat transfer surfaces, the system ensures high heat transfer efficiency, which can reduce chiller energy consumption by 10% to 40%.
2. Will the rubber balls damage the internal condenser tubes?
No. The balls are made of soft sponge material and are light in nature. They are designed to carry easily through the tubes by the flow of water without causing any surface damage.
3. What is the typical recovery period for the investment cost?
Due to significant energy savings and reduced manual maintenance/chemical treatment costs, the one-time investment cost can typically be recovered within one year.
4. Does the system require manual operation?
The system features full PLC computer programming control, which regulates the frequency of automatic cleaning daily, requiring no regular manual maintenance.
5. What is the efficiency of ball collection?
The system is highly efficient, with a ball collecting rate of up to 99%, ensuring continuous online cleaning without loss of cleaning media.
6. Can the system be used for industrial applications?
Yes, it is designed for industrial use, particularly for cooling tower condensers and heat exchangers in power plants and large-scale air conditioning systems.
