The 18-liter expansion vessel for solar systems is an essential component for absorbing variations in the volume of the heat-transfer fluid and maintaining stable circuit pressure. The SBR rubber membrane and Top-Pro internal anti-corrosion treatment ensure resistance and durability even under the demanding conditions typical of solar thermal systems, with a maximum operating temperature of 110°C. With a maximum pressure of 8 bar and a standard pre-charge pressure of 3 bar, it effectively protects the system from overpressure. The 3/4" water connection is positioned on the upper cap, with the water inlet facing downward for easy integration into the circuit. Its 18-liter capacity makes it suitable for medium-sized solar systems. A reliable, well-built solution to ensure safety and continuous operation over time.
