flat collector SX 2.0
Solar panels
Flat collector
Thermal solar systems convert solar energy into usable heat using SX collectors.
The heat generated in the solar collectors is transferred via the working medium to the domestic or domestic water storage tank and stored there. The efficient operation of the system is controlled by a temperature difference controller in conjunction with a circulation pump.
Innovative collector frame construction
The SX collector uses modern technology of aluminum frame bending. The technology consists in making the main frame from a single section of the profile without unnecessary joints in the corners. The frame without joints is much denser, looks more aesthetically pleasing and, most importantly, there is no risk of it coming loose after several years of operation. For additional protection against weather influences, the collector frame is powder coated.
Unique design of the absorber harp
The SX flat plate collector has an absorber that uses a modern technology for connecting the plate to the pipe system, which is unique on the market so far. The technology consists in partially rolling the copper pipe, which increases the transfer surface by seven times. Another advantage is that the connection, i.e. the solder, is located outside the main heat transfer surface. Considering that the thermal conductivity of the copper from which the plate and the pipe are made is 401 W/mK and that of the solder is only 60 W/mK, this is a significant advantage.
Unique design
The black color of the collector housing and the navy blue and black color of the absorber, which is visible through the solar glass, enhance any roof.
High performance
The excellent absorber, the well thought-out construction of the housing and the very good thermal insulation of the SX collector ensure a very high level of efficiency in both summer and winter.
Installation on any roof
Specially developed mounting units made of stainless steel and aluminum ensure quick and safe installation of the collectors on any roof with any type of covering.
standards and tests
The SX collector meets the requirements of the following standards: EN 12975; has a Solar Keymark quality test.
