Accumulators tanks (expansion tanks) for use with calorifiers and plumbing systems.  Our Italian made accumulators are suitable for marine, campervan, vehicle and domestic applications. They assist the smooth flow of water by compensating for unequal flows and expansion with heat. They can be used with hot and cold fresh water systems, chilled water plant and diesel and gas hot water systems. 


Accumulator material is steel coated with epoxy resin. The diaphragm is replaceable food grade rubber. A Schraeder valve is fitted on the top to permit the balancing of the air pressure.
