The Varem INOXVAREM stainless steel expansion vessel is a corrosion‑resistant pressure tank designed for potable water and pump systems. Constructed in AISI 304 stainless steel with a replaceable butyl membrane, the INOXVAREM range is ideal for hydro‑pneumatic installations, domestic water booster sets and commercial water pumps where long service life and hygienic construction are required.

Engineered to reduce pump cycling and protect systems from water hammer, these vessels act as a compact buffer for immediate water demand and to stabilise system pressure. Standard precharge (factory air pressure) is typically 2 bar and the series is rated for a maximum working pressure of 8 bar, with model‑dependent connections and capacities to suit small domestic to larger commercial requirements.

• Material: AISI 304 stainless steel (full RVS construction).
• Membrane: Replaceable butyl membrane suitable for drinking water.
• Temperature range: approx. -10 °C to +99 °C (model dependent).
• Pressure: standard precharge ~2 bar, max working pressure up to 8 bar.
• Typical applications: hydrofoor/hydro-pneumatic systems, pump protection, potable water systems, pressure stabilization.

Available capacities across the INOXVAREM line include small 1–8 L models through 20 L, 50 L and 100 L sizes (vertical and horizontal options), allowing you to choose the correct volume and connection for point‑of‑use, booster sets or whole‑house systems. Check model connection sizes (½", ¾", 1" etc.) when selecting the correct tank for your plumbing.
