Modular radiant air-conditioning system for heating and cooling of domestic environments mountable under-plaster both on the ceiling and on the wall, adaptable to all requirements as it can be resized depending on its structure.
It is a valid solution, applicable in all cases in which there is very little space for the system. It is also ideal as a thermal integration for other systems (e.g. bathroom). 
The WRS system has the advantage of having an extremely high thermal performance both when cooling and when heating, together with extremely low thermal energy due to the low thickness of the plaster.
The modules are made with PEX-C Ø 8x1 mm reticulated polyethylene pipe with oxygen barrier, fixed to the terminal board. The pipe is laid in the shape of a coil so as to guarantee the maximum thermal performance, having a homogeneous surface temperature given by the arrangement of the pipe which enables the passage of water with a cross flow.
The modules are connected to the linear manifolds, which are made of multilayer Ø 20x2 mm piping with oxygen barrier and include the fittings with two-sided couplings for the connection of the Ø 8x1 mm pipes of the modules to the main distribution lines.
The plaster must be chosen in such a way as to guarantee high thermal uniformity of the surface.
