Replenishing agent

A replenishing agent is a substance added to a system—such as a machine, process, or environment—to restore or maintain its optimal operating condition by replacing depleted or lost components. For example, in industrial or chemical applications, it helps ensure continuous performance by replenishing chemicals, lubricants, or other materials that wear out or are consumed during operation. Overall, it helps maintain efficiency, stability, and longevity of the system without unnecessary downtime or intervention.
