A separate, dedicated feed pump for every channel ensures greater efficiency and dynamics of cleaning. Many cooling channel cleaning systems on the market are equipped with a single feed pump. Such a solution creates many inconveniences that should be kept in mind when choosing a machine for channel maintenance. These include:
Device efficiency – the more cleaning sections the device has, the more channels we will be able to connect to it at the same time, maintaining an independent and repeatable dynamics of the cleaning process. Having said that, we need to remember that feeding multiple channels with a single pump connected to a manifold will give different results compared to a situation where we have individual channels connected to sections fed by a dedicated pump.
Cleaning time – Time savings we achieve by connecting several channels to one cleaning circuit is illusionary, because such a connection always generates much higher pressure drops, directly affecting the amount of liquid that we are able to pump in a given unit of time, and which has a direct impact on effectiveness cleaning. This is particularly important for single-pump devices, as cleaning efficiency in this type of design depends precisely on the ability of the system to pump as much liquid as possible. In practice, connection of cooling circuits in series requires a significant extension of the cleaning time, at the same time giving no guarantee that all lines will be cleaned equally. Individual connection of channels gives us much greater possibilities of monitoring and controlling both the dynamics of the process, as well as the assessment of its effectiveness.
Measurement of the flow rate – In the case of a single-section device to which the channels are connected in series, the performed flow measurement will not inform the user about the actual flow improvement for individual circuits, but only about the sum of flow rates, which can be compared ‘before and after’ the process. The user will not be able to tell what increases in flow rate values were achieved and whether all channels were actually cleaned to the same degree.
Leakage detection – The bridging of the system has one more, very significant disadvantage. In the event of a leakage, we are often unable to precisely determine which channel has caused it. When we connect the channels individually, finding the cause of the leak is much easier.
