Expanzomat

An expanzomat (also called an expansion vessel) is a device used in heating and cooling systems as well as fluid media systems to compensate for changes in volume due to changes in temperature and pressure. Its main task is to ensure proper compensation of the thermal expansion of the fluid in the system.

How the expander works: The expander consists of a container that is separated from the interior space by a membrane or a moving float. Air or an inert gas (such as nitrogen) is placed in this container. As the fluid heats up and increases in volume, the expansion valve allows some of this increased fluid to pass into the container, thereby maintaining a constant pressure in the system. As the fluid cools and its volume decreases, the expansion valve allows some of the fluid to return back into the system.

Expansomat Uses: Expansomats are often used in boiler heating and cooling systems, water heating systems, cooling circuits and other similar applications. Their main goal is to minimize pressure changes in the system due to changes in fluid volume due to temperature changes. Without an expander, the system could fail under certain conditions or damage components due to excessive pressure.

Overall, expanders ensure that systems run smoothly and safely, minimizing the risk of damage and extending component life.
