The expansion tank of a car is nothing more than a small tank connected to the cooling system, and the expansion vessel is an instrument that is mounted on the vehicle and has the function of collecting the water that will be purged from the radiator cover . What is an expansion tank? The expansion vessel is basically a glass or small tank of thermoplastic polymer, which has the task of collecting the water that comes out of the radiator. When the latter is heated inside, obviously pressure will be created; This pressure is regulated and kept under control by the valve located on the radiator cap, generally the pressure is less than 1.1 bar. | | |

In general, the expansion vessel is printed with our ethylene glycol-resistant 20% polypropylene fiberglass which is used to prevent freezing of water at temperatures below zero. The 2 housings are injected, the upper one in transparent fiberglass polypropylene, to allow the liquid level to be seen, and the lower housing in black fiberglass polypropylene, then the two housings are welded with a hot blade. |
