Hewalex - Model KS2000 TLP - Solar Collector
Flat plate solar collector KS2000 TLP is an uncompromised solution in terms of construction and parameters among flat plate collectors. The absorber is made entirely of copper (Cu-Cu) and welded with ultrasonic welding. High efficiency is achieved through highly selective coating (PVD), glass providing high permeability to solar radiation U1 and full thermal insulation of the casing.

Thanks to its design and characteristics, the KS2000 TLP solar collector is an excellent product in the flat plate solar collectors category. The absorber is made of copper only. The connection between the copper pipes and the absorber plate is made using the state-of-the-art ultrasound welding method.
The use of structural glass pane of the highest solar radiation transmittance class (U1) leads to a high optical efficiency of 80.2%, confirmed in tests performed at the Institute for Solar Technology in Rapperswil, Switzerland. Mineral wool thermal insulation whose thickness is increased to 50 mm and a 20 mm thick insulation of the walls of the housing ensures low heat losses. The powder painted housing is an element of an attractive design of the solar collector.
Features of the solar collector:
- the KS2000 TLP version has an ash-brown painted housing (RAL 7022)
- the cover of the housing is made with structural glass providing high permeability to solar radiation (91.6%, representing the highest class U1)
- the absorber is fully made with copper
- a parallel (“harp”) arrangement of copper pipes provides minimum flow resistance, reducing electricity consumption by the circulation pump and enabling rapid emptying of glycol from the pipes in case of overheating and stagnation of the collector (when boiling and evaporation occur)
- the absorber is covered with a BlueTec layer produced using oxides of titanium and silicon, with good selectivity properties (absorption 95%, emission 5%)
- low heat losses to the environment are ensured by the use of thermal insulation made of mineral wool, 55 mm thick on the bottom of the housing and 20 mm thick on the side walls
Ways of installing the solar collector
Flat collectors require as standard a certain inclination from the horizontal to ensure proper operation. For year-round operation, an inclination of between 30o and 60o from the horizontal is recommended. When a collector is installed on a roof with smaller inclination, adjusting fasteners are used. It is also possible to install KS2000 TLP solar collectors on the elevation of a building, at ground level or on a flat roof. We offer universal constructions for this purpose.
Solar collector performance
The parameters of the KS2000 TLP solar collector have been measured in tests carried out at the SPF Rapperswil institute in Switzerland. The optical efficiency of 79.4% relates to the aperture surface area (active surface).
Solar collector quality
The quality of the KS2000 TLP solar collector is confirmed by a SOLAR KEYMARK certificate. Collectors with this document comply with the quality requirements of the PN-EN 12975 standard. The quality tests performed on collectors are based on a 20-year minimum life cycle. Hewalex solar collectors have been sold in Poland and abroad for more than 20 years.
Comprehensive range of solar installations
KS2000 TLP solar collectors can be used both in small installations and in large systems in public and industrial buildings and the like. The system can be configured for this purpose based on a comprehensive range of hot water heaters, universal heaters to support central heating, pumping and control units, and other equipment.
