Heat exchanger ball cleaning

Technology / Service Summary

The system prevents adhesion of dirt whenever the target machine is in operation, thereby preventing the deterioration of machine operating efficiency or problems associated with the corrosion of tubes.
The only maintenance required is the replacement of natural rubber sponge balls. This results in low running costs.
The mechanism of the ball cleaning system is simple. The system passes sponge balls through the tubes of a shell-and-tube heat exchanger to physically clean the tubes.

Purpose

No environmental impact because no chemicals are used. No equipment damage caused by chemical cleaning. This prolongs the life of the equipment.

Feature

The system prevents adhesion of dirt whenever the target machine is in operation, thereby preventing the deterioration of machine operating efficiency or problems associated with the corrosion of tubes.
