Topway S - 1” return manifold in steel, making it possible to set the temperature of each room through the application of electrothermal actuators, so as to automatically regulate each circuit with a thermostat.
The Topway S manifold is made from a high-resistance material, AISI 304 stainless steel (brushed finish) with high Nickel content, copper-free, for improved resistance against corrosion, safer use and enhanced durability.
It can be completed by all essential components, and also: adjustable drain valve, air vent valve, electrothermal head.
Its careful design ensures fast and safe installation; all the elements can easily be combined with one another.
The high quality standard of the materials used, the sturdiness of the components and the degree of finishing make the Topway S System reliable and functional over time, extending the service life of the system and reducing the need for maintenance.
The quality guarantee is the result of its highly automated production, which determines the consistency of the constructional and fluid dynamic characteristics of the entire production batch.
All the components are subjected to strict controls and additional tests are carried out at the hydraulic workbench to check the performance in critical operating conditions.
