Expansion Vessels
When a boiler is heated, water in a heating system expands as a result of thermal pressure. Expansion vessels – also known as expansion tanks – are used to manage the increased volume and pressure of the heated water.
Diaphragm expansion vessels offer a simple and intelligent solution that will maintain the correct pressure for the perfect functioning of a heating system. They operate without an electrical current, compressor or pump, instead a diaphragm separates the vessel into a water and gas chamber preventing the gas from diffusing into the water.
Reflex Expansion Tanks
The Reflex range of diaphragm expansion vessels can be used for a wide range of pressure ranges and nominal volumes, flat or cylindrical in shape depending on the installation site, and with fixed, half diaphragm or exchangeable bladder (full diaphragm).
Tubman Heating has a range of Reflex expansion tanks available, from 8 litres – 500 litres capacity.
