Expansion Vessels for Portable Water

High-quality Flamco pressure tanks are also commonly referred to as expansion vessels because they are used in domestic cold water supply and booster pump systems. The term pressure tank is widely used by professionals in the MEP and plumbing industries, as the tank stores a reserve of pressurized water to reduce frequent pump start-stop cycles. However, the same vessel can also be installed in closed-loop HVAC systems to accommodate the expansion of heated water, preventing excessive pressure, pipeline leakage, and damage to the system. This is why it is also known as an expansion vessel. Fundamentally, an expansion vessel is designed to a higher standard, as its diaphragm is capable of withstanding continuous operating temperatures of up to 70°C, whereas conventional pressure tanks are generally manufactured for cold water applications only. As a result, standard pressure tanks are not suitable for hot water circulation or HVAC systems because they are unable to withstand the sustained operating temperatures. PGTECH, the official representative of Flamco Netherlands in Vietnam, supplies a comprehensive range of pressure tanks and expansion vessels, including WRAS-approved potable water models that comply with international standards. Flamco expansion vessels are recognized for their outstanding durability, operational safety, and reliable performance, making Flamco one of the world's leading expansion vessel brands.
