    Mini Shock Arrestors for Cylinders are compact devices designed to protect sealed hot water and heating systems from pressure surges and water hammer caused by rapid changes in flow. These small but essential units prevent system damage, reduce noise, and extend the lifespan of boilers, valves, and pipework in domestic and commercial heating installations

    About Mini Shock Arrestors

    Mini Shock Arrestors absorb sudden pressure spikes within unvented cylinders and sealed heating systems. They typically contain a compressed air or nitrogen chamber separated from the system water by a flexible diaphragm. When a surge occurs, the diaphragm flexes to absorb the impact, preventing stress on the heating system components. Their compact design allows easy installation in tight spaces, making them ideal for modern heating systems.
