The Flamco Contraflex 150 l pressurised expansion vessel is designed for sealed heating and cooling systems. When the medium is heated, it compensates for the increase in volume and helps maintain the system pressure at the correct level. The vessel is fitted with a flexible SBR rubber diaphragm with a rolling action and is nitrogen-charged for improved long-term retention of the pre-charge pressure. Each unit is factory tested and the design complies with the requirements of PED 2014/68/EU.
