As you turn on any process, but specifically spray, maybe your pumps are going to create sheer and that sheer is going to create inorganic heat. With some time, it will heat up the wash bath and the temperature of the bath. Typically, it doesn’t heat it up a whole lot, but again it depends on the size of your tank and pumps. Generally you might see 120° maybe up to 130° F but again that’s after running it all day, times zero it’s going to be room temperature depending on where you live.
