Product Description Horizontal Diaphragm Membrane Pressure Tanks Vessels of 50 Liter CapacityProduct DescriptionCuztomized Export Model is the model for Export Only,In order to protect our oversea area dealers ,no sales to inside China, only direct export to authorized countries.Or you can find the equivalent model from our open modelsThere are two main types of Expansion Vessel dependent on what application you have. You will normally find a Red Vessel (Heating Vessels) to be used on a Sealed System Heating application whilst the most common use for a Blue Vessel or White Vessel (Potable Vessels) would be in a potable application such as an Unvented Water Heater or a Pumped System.Potable Expansion Vessels are built from different materials than Heating Expansion Vessels to ensure that the water is contaminant free and safe for human consumption. Expansion Vessels operate on the basis that the internal chamber is separated by a rubber membrane, inside this membrane sits the water and surrounding this sits a pocket of air--For some models are filled with nitrogen gas up to 99.9% purified. As the water inside the sealed system is heated the water pressure increases, as water is non compressible the air inside the air chamber of the Expansion Vessel will become compressed thus leaving the system safe from over pressurization. As water can increase by 4.5% volume when heated from 0-100 DegC an Expansion Vessel is a vital part of any sealed heating system.Expansion Vessels can be supplied with a replaceable or fixed membrane depending on your preference and the pressure within the Vessel is set using a Schrader Valve just like you would find on a bicycle tyre.Expansion Vessels are commonly used on pumped systems to remove the requirements of a continuous pump. This works as the user will set a low and high pressure on the pump settings, when the water pressure reaches the lowest setting the pump will engage and fill the Expansion Vessel to the high pressure point and stop. Once this cycle has been completed the Expansion Vessel puts the stored water under pressure ensuring higher pressure water. This will continue until the Expansion Vessels pressure drops to the lower point and the pump starts its cycle again.At Taizhou Tianyang Electrical Co.,LTD, we manufacture Expansion Vessels according to afferent requirements from other clients , to help you find the vessel you require please find below contact information of our sales staff,we can make our best offer to you as soon as your details requirements come.Please find the open model by referring to our catalog.We have a lot of stock for fast shipment with Dezhi/Auqa Leader Brand.If you have your own drawing for tanks or your own trade mark for OEM Service,feel free to contact us.Cuztomized Export Model is the model for export ONLY. In order to protect our area oversea dealers ,no sales to inside China ,only direct export.DescriptionAn expansion vessel, pre-charged with nitrogen instead of compressed air, to meet the requirements of most heating systems and for use with potable water. The Expansion vessels for potable water systems are manufactured to meet the requirements of PED 97/23/EC Directive and BS EN 13831:2007 'Closed expansion vessels with built in diaphragm for installation in water'.Why use Nitrogen Instead of Compressed Air?The oxygen in compressed air permeates through the membrane, reducing the pre charge pressure. Duringnormal function, oxygen oxidizes the membrane in the vessel, causing under-inflation and deterioration of the rubber.Dry nitrogen by comparison maintains proper inflation pressure longer, will not corrode the inside of the vesseland extends valve and expansion vessel life. Industry research indicates that oxidative aging is one ofthe primary causes of decreased vessel life. Oxidative aging that is caused by the diffusion of oxygen from thepressurized air cavity of the vessel to the outside atmosphere.Tests have shown that if vessels are inflated with nitrogen, there is a significant reduction in failure.How does Nitrogen help?While both nitrogen and oxygen can permeate rubber,nitrogen does it much more slowly. It might take 6 monthsto lose 2psi with nitrogen, compared to just a month with air. And nitrogen is far less reactive. It doesn't cause rustor corrosion on steel or aluminum, and it doesn't degrade the rubber seal used in the pre charge valve extending valve core life and help prevent core leaks.Technical Parameter NamePotable Water Expansion VesselApplicationFor sanitary hot water systemsMax. working pressure10 barMax. temperature100°CFactory air pre-charge2.0 bar nitrogenCapacity50 LtrUseful Capacity40 LiterShellCarbon steelConnectionsG Stainless Steel Grade 304DiaphragmReplaceableMembrane Material Synthetic rubber compoundVessel Diameter410 mmVessel Height610 mmTechnical Drawing For Your ReferenceDifferent Optional Flange/Membrane For Our Dealer OnlyCompany Profile Taizhou Tianyang Electrical co.,LTD.
