Oxygen diffusion density
Explained for youOxygen is one of the most important elements that we know; it is necessary for our survival. However, it is not always desirable at every location since it can also cause all kinds of corrosion (including rust). Rust and residue in a water-carrying system can contaminate the valves and pipes of the (climate) system and eventually even clog them. Oxygen diffusion density is the key word here. In this article we explain what it is and how you can assess whether a system has a good oxygen diffusion density so that you can enjoy the comfort of your climate ceiling for a long time.
What is it and which factors play a role?
The more oxygen enters the water that runs through the installation, the greater the chance of corrosion forming in the system. Water flows not only through the pipes, but also through pumps, (control) valves and distribution stations. Too much oxygen in the water will attack metals such as steel, cast iron and brass and will mean faulty pumps, stuck valves or malfunctioning control valves. In addition, the rust particles are fed through the system and adhere to the bottom of the pipe, especially in the event of a water shutdown. This can cause pit corrosion, which will eventually lead to leakage.
In the world of climate ceilings, we know the term oxygen diffusion density. This term indicates how closely oxygen diffusion a certain material is. Steel and copper pipes are 100% oxygen diffusion tight, but plastic pipes are not. If plastic tubes are oxygen-diffused according to DIN 4726, the degree of oxygen diffusion is within the specified standard. The oxygen diffusion density of the climate ceiling with plastic pipes depends on:
- the type of material used;
- presence of diffusion inhibiting layer;
- the thickness of the material;
- the amount of plastic pipe used per m² ceiling;
- whether or not the pipe is trapped (thermal conductivity profile).
How do we apply this knowledge in our systems?
With the above knowledge in mind, our R&D department set to work and the OxzeRo system was developed; Because the oxygen diffusion density of the climate ceiling is not limited to the use of a plastic hose that meets the DIN 4726 standard, the amount of plastic pipe wall through which oxygen diffusion takes place is minimized in the OxzeRo climate system.
In addition, we always use copper pipes or plastic pipes with an oxygen diffusion-inhibiting layer that comply with the DIN 4726 standard for heat transfer. Our plastic distribution pipes are equipped with an aluminum intermediate layer so that no oxygen diffusion can take place.
In addition, the plastic pipes in the OxzeRo system are clamped over the full length (so not only at a few points) in a heat conduction profile. This limits the exposure of the plastic pipe to the outside air and reduces the oxygen diffusion.
So climate control is not just about how hot or cold it is, it's also about how you can build a system that will give you many years of pleasure. And we like to think about that!
OxzeRo - oxygen diffusion dense climate system from Inteco
On this page you have received information about oxygen diffusion density and more importantly: how you can guarantee that applying a plastic climate system is also the right choice in the long term.
Inteco has successfully applied this knowledge for years with the OxzeRo climate system. The OxzeRo climate system is distinguished by its high oxygen diffusion density (compared to solid plastic climate systems), up to 10 times better than on the market solid plastic climate systems that are referred to as oxygen diffusion-proof.
