Reliance RWC 100 Litre Aquasystem Potable Expansion Vessel Pre Set 3.5 Bar - XVES050110
Stainless Steel Expansion Vessel for Potable Water Applications
The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to accommodate the increased load within water systems as water is heated and expands. These expansion vessels play a crucial role in maintaining safe operating levels, preventing excessive pressure build-up in both sealed heating and cold water systems. Each vessel features a replaceable membrane that safeguards against corrosion and contamination, ensuring that the water remains safe for human consumption. The inclusion of a replaceable membrane also facilitates easy servicing of the vessel without requiring removal, allowing for quick maintenance in situ.
Features and Benefits:
- Stainless Steel Bolted Flange: Resists corrosion for enhanced durability.
- Extra Wide Membrane Opening: Reduces noise caused by restricted flow for a quieter operation.
- Internal Membrane Protection: Ensures no contact between water and the steel shell, preventing internal corrosion.
- Comprehensive Size Range: Available in sizes from 2 to 5000 litres, catering to all applications.
