BALL MONITOR Keeping the correct number and size of cleaning balls in condenser tubes is essential for efficient power plant maintenance. As a leader in Condenser Tube Cleaning Systems, TECHNOS has developed tools to guarantee better functioning of equipment. WHAT HAPPENS WHEN BALLS ARE NOT MONITORED ? Leaving worn-out balls in circulation can have COSTLY CONSEQUENCES: LOSS OF CONDENSER EFFICIENCY, and therefore LOSS OF PRODUCTION and eventually leading to the potential need to perform risky mechanical or chemical cleaning on dirty tubes. Operators periodically check the number and diameter of the balls in circulation. However, relying on a manual sieve with calibrated holes to identify worn-out material is time consuming and often leads operators

to renew the complete ball load at routine intervals. This can obviously lead to excessive ball consumption and its associated costs.
