When it comes to the design of our Ray Magic panels, specifically the NK, G, and Q series, a vital component is the radiant tubing. We use an 8mm PE-RT tubing with an Oxygen barrier. A standard in Europe for the past 35 years for radiant applications, PE-RT offers several benefits which make it ideal for our panels.
Advantages of PE-RT Tubing
PE-RT tubing provides exceptional flexibility, which allows it to be easily shaped with a small radius of just 2 inches. This flexibility allows for a pattern of 3 15/16″ (100 mm) on center.
A key advantage of PE-RT is its minimal expansion and contraction due to temperature changes (within the range of 50F-120F). This results in reduced friction and noise between the tubing and the aluminum plates, which improves the performance and lifespan of our panels.
Moreover, using PE-RT contributes to the overall recyclability of all component parts of the panels, including the EPS and aluminum.
Recommended pipe for connections
For seamless connections from manifolds to the panels, we recommend using our pre-insulated PEX-A pipe. This choice is primarily based on its popularity in the US market and its compatibility with the widely-used F1960 fittings technology. This ensures easy installation and reliable connections.
