Maybe you forgot to add antifreeze. First, let’s see the performance requirement on antifreeze for chiller and compare various types of antifreeze on the market. Obviously, these 2 are more suitable. To add antifreeze, we must first understand the ratio. Generally, the more antifreeze you add, the lower the freezing point of water, and the less likely it is to freeze. But if you add too much, its antifreezing performance will decrease, and it is pretty corrosive. Your need to prepare the solution in proper proportion based on the winter temperature in your region.Take the 15000W fiber laser chiller as an example, the mixing ratio is 3:7(Antifreeze: Pure Water) when used in the region where the temperature is not lower than -15℃. First to take 1.5L of antifreeze in a container, then add 3.5L of pure water for 5L mixing solution. But the tank capacity of this chiller is about 200L, actually it needs around 60L antifreeze and 140L pure water to fill in after intensive mixing. Calculate...
