Megaflo HEInnovative technologyCylinder constructionDuplex stainless steel offers a superior resistance to corrosion especially inaggressive water areas, compared with some grades of stainless steel, glass-linedsteel and copper. Because Duplex is a low carbon, high chromium content alloy, itresists all forms of corrosion including pitting, crevice corrosion, uniform corrosionand stress corrosion cracking, without the use of a sacrificial anode. In addition, thetungsten inert gas welding coupled with the special post weld processes ensuresthe same level of corrosion resistance and mechanical strength as the parent metal.This ensures the longest possible working life for every cylinder.The combination of its lightweight and very strong construction makes Megaflo HEeasier to handle on site. Every unit is pressure tested in the factory to 15 bar – fivetimes the normal operating pressure – making Megaflo HE suitable for all domesticand commercial applications.No sacrificial anode is required with Megaflo HE. With inferior grades of stainlesssteel, glass-lined steel and copper, sacrificial anodes are required to achieve adegree of corrosion resistance. However they require regular replacement which,if not carried out can result in premature cylinder failure. Megaflo HE overcomes anyneed for this by using top quality Duplex stainless steel.Specification comparison to a copper unit with air gapTypical maximum working pressureTypical operating pressureMaterialMegaflo10.0 bar3.0 barDuplex stainless steelCopper4.5 bar2.1 barCopper4
Internal air gapThe internal air gap and floating baffle system allowsfor a compact self contained unit which eliminatesthe need for an external expansion vessel and allowsfor a quicker and simplified installation.Megaflo HE meets the BBA internal expansion volumeendurance test with no reduction in operating pressureor flow rates.Floating baffleExpanded water is accommodated within thecylinder using an internal air gap maintained by apatented floating baffle. This baffle floats on thesurface of the water within the cylinder to maintainthe integrity of the air gap.Before expansionAfter expansion5
