Often first-line products become darker in color
Thread Content
Often the color of the first-line product becomes darker, but often the color of the second and third products is normal, and the heat exchanger does not leak. What is going on and how to deal with it?
Is the oil extracted by your device too heavy, or the oil refined by the device is too heavy, or is the color of your oil itself heavier?； If there is no leakage in the heat exchanger, it is basically the fault of the oil itself.
