Has antifreeze been added to the circulating water system? How effective is it, and is the cost high?
If the circulating water is working properly, isn’t it supposed to circulate? Are there dead corners that are worried about freezing? Adding a small bypass is also an option; the components of antifreeze are inorganic substances that may form scale and crystals ； For organic substances, it requires even more medication
It is feasible to add antifreeze (usually ethylene glycol) to a closed-loop water system, whereas it is not feasible to do so in an open-loop water system, as the mist carried by the cooling tower leads to losses of antifreeze and also causes contamination.
Haven’t done it this way before. Unless it is a small system, circulating water usually has a relatively high temperature; as long as there is flow, that is sufficient. If local bypassing, thermal insulation, and heat tracing are not feasible.
