China Water Heater Expansion Tank Water Heater Expansion Vessel Expansion Vessel

Expansion Vessels - Why?In practice water cannot be compressed and therefore any increase in water volume must be accommodated in an expansion vessel designed and sized for that purpose. Naturally, as water heats up, it expands. This expanded water has to go somewhere. In an open type sMass Transfer and Separation Equipment ystem the open expansion tank situated at the highest point of the system would accommodate this extra volume. A closed type system does not have an open fixture such as described above. Hence, a correctly sized Dezhi/Aqua Leader expansion vessel is necessary. When properly sized, the Dezhi/Aqua Leader Expansion Vessel will accommodate the expansion of the fluid during the heating or cooling cycle without allowing the system to exceed the pressure limits of any of the components in the system.
Configuration and FeaturesDezhi/Aqua Leader Expansion Vessels incorporate a diaphragm/bladder arrangement which provides a flexible barrier between the system fluid and the precharged air in the vessel. As the sysWelding Equipment tem water expands, the bladder also expands pushing against the precharged air cushion. This is how the expansion is accommodated in a closed-loop system.Standard construction is carbon cold pressed steel with natural rubber or EPDM membranes.Temperature limits are 10oC to 99oC.Working pressures vary from 3 Bar to 35 Bar depending upon which vessel is selected. Higher pressure ratings of 45 and 50 Bar are available if required.Other Features• Replaceable bladder• Threaded connections - stainless.• Pre-set pressure 400KPa - variable.• Wall mount bracket available for 8-36 litres.• Also available in stainless steel.• Relief valve supplied loose to suit system pressure - please specify.Sizing for Expansion VesselsIn order to select a suitably sized expansion vessel, the following information is required:• Total system water volume in litres.• Temperature of water when system is filled (in oC) and average maximum operating temperature (in oC).• Minimum operating pressure in kPa and maximum operating pressure (10% below relief valve, in kPa).• Which level of the building it will be installed and number of levels there are above it?Suggested Specification Expansion Vessels shall be the closed type similar to Dezhi/Aqua Leader (available from Taizhou Tianyang Electrical Co., Ltd ) or approved equal and suitably sized to suit the system temperature and pressures likely to be encountered. Vessels construction to be fully welded and sealed steel construction, complete with integral EPDM rubber liner to maintain the water within the system without exposure to air or contamination. Each Vessel to be supplied with a suitably safety relief valve vessel must have a replaceable bladder.Taizhou Tianyang Electrical Co., Ltd reserves the right to make changes without notification.
Introduction

Dezhi expansion vessels are suitable for use in central heating and cooling installations.

Nitrogen, a dry inert gas used in the Dezhi/Aqua Leaderrange of expansion vessels, improves the vessel's life span by reducing corrosion inside the vessel, and prevents loss of pre-charge pressure. Nitrogen permeates through rubber slower that oxygen and is far less reactive to both steel and aluminium creating fewer debris inside the vessel. Nitrogen does not degrade rubber prolonging the membrane life.

Oxygen in compressed air permeates through the membrane, thus reducing the pre-charge pressure over time. During normal operation, oxygen oxides the membrance in the vessel, causing under inflation pressure and will not corrode the inside of the vessel.

It's recognised in the industry that oxidative ageing is one of the primary causes of decreased vessel life. Tests have shown that if vessels are inflated with Nitrogen, there is a significant reduction in failure and increased vessel life.

For use under high pressure. Top-quality high strength steel, with a gleaming red (RAL 3002) epoxy powder coating - perfect protection and finish. Clamp ring of heavy-duty thermally-galvanised steel. Our flexible EPDM Bladderwith rolling action are suitable for use with glycol based anti-freeze addition up to 50%. Exact details are available on request. The nitrogen airvalve is sunk and cannot be damaged due to the cap and extra protective plastic beige coverplate. Uncoated threaded system connection, ensuring problem free connecting.

Specifications

Max. working pressure: 10bar(g)Max. temperature at (heating) outlet: 99°C.Max. temperature diaphragm: 99 °C (DIN4807/3).Max. supply temperature (boiler): 90 °C.Min. working temperature: -10 °CIn accordance with Pressure Equipment Directive 97/23/EG.
The main elements of the membrane tank are a metal case of high-quality deep-drawn steel and an elastic membrane made of Butyl Rubber Membrane separating the tank into two chambers - an air (cavity between the metal case and a membrane) and a water one (the internal cavity of the membrane).The air chamber is constantly under a pre-set air pressure. The service life of diaphragm tanks is at least 10 years of continuous operation.The durability of the membrane - at least 100,000 cycles.Dupont (France) materials are used as paint.Features of the design - the location of the top flange (TOP tanks) provide ease of installation / disassembly of the equipment, virtually eliminates the possibility of air plugs in the water cavity of the membrane, the minimum time required to replace the membrane;small overall dimensions.Company profiSecurity Guard le
