A separate, dedicated feed pump for each duct provides greater cleaning efficiency and dynamics. Many cooling duct cleaning systems on the market are equipped with a single feed pump. However, such a solution creates a number of inconveniences to keep in mind when choosing a duct maintenance device. Among the most important of these are:
- Performance of the device - The more cleaning sections the device has, the more channels we will be able to connect at the same time, maintaining independent and repeatable dynamics of the cleaning process. However, it should be noted that feeding multiple channels with a single pump connected to the manifold will give different results compared to the situation where we have individual channels connected to sections fed by a dedicated pump.
- Cleaning time - The time savings achieved by connecting several channels to a single cleaning circuit are illusory, because such a connection always generates much higher pressure drops, which directly affects the amount of liquid we are able to pump in a given unit of time, and thus the cleaning efficiency. This is particularly important in the case of equipment with a single pump, since the cleaning efficiency in such a solution depends precisely on the system's ability to pump as much liquid as possible. In practice, connecting cooling circuits in series requires a significant increase in cleaning time, while at the same time providing no guarantee that all lines will be cleaned equally. The individual connection of the ducts provides much greater opportunities to monitor and control both the dynamics of the process and evaluate its effectiveness.
- Flow measurement - In the case of a single-section device to which the ducts are connected in series, the flow measurement taken will not inform the user of the actual flow improvement for the individual circuits, but only the sum of the flows, which can be compared "before and after" the process. The user will not be able to assess what increments in flow values have been achieved and whether all channels have actually been cleaned equally.
- Leak detection - Combining cooling circuits into a single system has another very important disadvantage. In the event of a leak, we are often unable to determine precisely which channel caused it. When the ducts are connected individually, it is much easier to find the cause of the leak.
