Expansion

Expansion is a physical phenomenon that occurs when the temperature of a material changes. Since most materials have different thermal expansion at different temperatures, their volume or dimensions change. Thus, dilation refers to the expansion or…

expansion belt

It serves to prevent thermal expansion during the expansion of the floor heating and to prevent the transmission of noise between structures, e.g. wall and floor. At the same time, thanks to the additional film, it prevents the screed from leaking…

expansion valve

The expansion valve is an important part of refrigeration and air conditioning systems, which is used to regulate the flow of refrigerant and its pressure in the refrigeration circuit. Its main purpose is to ensure that the refrigerant passing…

expansion vessel

An expansion vessel is a vessel that serves to balance changes in liquid volume caused by temperature changes. It works as an excess pressure regulator in the system. Expansion vessels are commonly used in heating and solar systems and can also…

fancoil
