Flamco - 2 Ltr - Flexcon Premium 2 Expansion Vessel - Pre-Charge 0.5 Bar - End Pressure - 6 Bar

Flamco - 2 Ltr - Flexcon Premium 2 Expansion Vessel - Pre-Charge 0.5 Bar - End Pressure - 6 Bar - 16937

For sealed heating installations (acc. to EN12828) and chilled water (cooling) installations.
Expansion vessels keep the pressure of the system installation stable by temporarily absorbing the extra water volume that is generated by heating or cooling installations.

• Sustainable expansion vessels thanks to innovative technology
• The Flexconn Premium expansion vessels have a plastic membraine (12 - 35 Litres) manufactured from thermoplastic polyolefin (TPO). The new membrane has a high flexibility and low permeability. The environmental performance of the new membrane is much better and TPO can be burned cleaner or recycled into products more effectively.
• The plastic membrane is much lighter because it requires up to 50% less material. This saves raw materials, energy (production) and fuel (transport) and results in a large reduction of CO2 emissions.
• THe box is made from FSC certified carboard and the version with the lowest available as an option CO2 footprint has been selected. THe manual is printed on FSC certified paper.
• A long service life is guarenteed with a 15-year warranty and therefore also saves on maintenance.
• Extrememly low permeability of the diaphragm ensures that pre-charge pressure is maintained for longer.
• The flexible diaphragms, with rolling action, are performed and, in contrast to a bag type bladder, prevent stretching so their properties are preserved over the long term.
• Two halves of the vessel are coated prior to assembly, not afterwards. Therefor there is no risk of corrosion on the clamp ring and the diaphragm does not have a service life-reducing thermal shock during production.
• The unique zinc plated steel clench ring construction clamps the diaphragm between the two deep drawn vessel halves. This not only ensures a perfect seal but also prevents mechanical damage of the diaphragm during use (system load distribution over the entire clamping area and not at 1 central suspension point)
• The gas side is filled with nitrogen, and not air, so that corrosion is prevented and the pressure loss is even more limited.
• The nitrogen air valve is countersunk on the vessl to protect it form damage, it is in turn further protected by a cover plate from recycled plastic.
• The profile on the diaphragm prevents it from sticking to the inside wall of the vessel and ensures inflow of expansion water at the earliest increase in pressure.
• The uncoated taper water connection thread ensures easy and water tight system installation
• FInished with a gleaming epoxy-powder coating
• Each vessel is functionally tgested before it leaves the factory
