Solar collector SUNTIME 2.5 - 5,5 m2



The construction of solar collector SUNTIME 2.5



The heart of SUNTIME is a full copper soldered absorber with high selective coating Sunselect, Eta+, TiNOX (95% convertion of solar radiation into heat and max. 5% loss by heat emission). The frame of the collector is produced from anodised aluminium profiles which do not require further usage of more glazing profiles.

The design of the frame prevents from capturing of snow on the front surface; this significantly increases the solar gains in wintertime. The front surface is covered with 4mm-thick solar hardened glass. For reduction of heat losses, the back surface is insulated with 30mm-thick mineral wool and 20mm-thick PUR-plate. The lateral surfaces are insulated with 20mm-thick mineral wool. SUNTIME is connected to the solar circuit with copper tubes with a 22mm diameter
