Heatrae Sadia Megaflo HE Sales Brochure - Advanced Water

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
