Expansion vessels

Aquafer expansion vessels are the ideal solution for ensuring safety and performance in hot and cold water systems. Designed to absorb pressure variations caused by thermal expansion or pressurization, they protect equipment such as storage water heaters, solar panels, boilers, and HVAC circuits, extending their lifespan. With PED (2014/68/EU) certification, they meet the strictest European safety and quality standards.

Made with high-quality materials – carbon steel with epoxy-polyester coating or stainless steel – our vessels offer durability, corrosion resistance, and versatile installation for domestic, commercial, and industrial applications. Whether for domestic hot water, solar circuits, or potable water pressurization, Aquafer has the perfect solution.
