    • The Reliance RWC Aquasystem AR18 is a premium, 18-litre potable expansion vessel designed to safely absorb thermal expansion in unvented hot water systems. Built with a high-durability, white epoxy-coated steel body, it features an advanced replaceable membrane that completely separates the water from the air chamber. This design prevents internal corrosion, pressure loss, and water contamination. The vessel is engineered with an extra-wide membrane opening and a robust, bolted stainless steel flange to eliminate flow noise, making it an ideal choice for quiet domestic and light commercial installations.
