The ELBI drukvat HM 24 S/Steel is a 24‑litre stainless steel expansion/pressure vessel designed to stabilize system pressure, reduce pump cycling and protect pumps and boilers in potable water and hydronic systems. Built for durability and reliable pressure support in booster and heating/cooling applications, this compact stainless steel vessel offers corrosion resistance and long service life for medium-sized installations.

Key features include a 24 L capacity and an 8 bar maximum rating, making it suitable for many domestic and light-commercial booster or heating systems where pressure buffering and water separation are required. The vessel’s diaphragm design separates the air cushion from the water volume to prevent waterlogging and maintain consistent precharge behavior, improving energy efficiency and reducing pump wear.
