Robust 50‑liter stainless steel expansion vessel engineered for potable water and heating systems. The HXV 50 combines a corrosion‑resistant stainless inlet and durable external finish with a factory‑installed flexible butyl membrane to control thermal expansion, stabilize system pressure and prevent waterlogging. Built for vertical installation, this compact pressure tank suits domestic and commercial hot water, solar and closed heating circuits where a reliable membrane expansion tank is required.

Key features

• Capacity: 50 L (compact 50‑liter vessel)
• Stainless steel inlet and corrosion‑protected body for long life
• Fixed butyl membrane (food‑grade, non‑taste) for sanitary water applications
• Rated up to 10 bar working pressure; hydrostatic test values per manufacturer guidelines
• 1" male threaded connection for standard plumbing integration
• Factory precharge and serviceable air valve for on‑site adjustment

These features make the HXV 50 an ideal expansion tank / pressure vessel for applications requiring a sanitary membrane solution and reliable thermal expansion control.

Specifications & installation notes

Operating temperature range: approximately -10°C to +99°C. Maximum allowable operating pressure typically 10 bar; factory air precharge around 2.5 bar (adjustable on site). Install vertically where indicated, fit using the 1" threaded connection, and follow local codes for pressure vessel mounting and safety. Regular inspection of the diaphragm and precharge improves longevity and prevents service interruptions.

Applications & benefits

Use as a stainless steel expansion tank, membrane expansion vessel, or thermal expansion absorber in domestic potable water systems, hot water heaters, solar thermal loops and closed heating circuits. Benefits include corrosion resistance, sanitary membrane protection, compact footprint, easy plumbing integration, and reduced pump cycling for system longevity.
