Blue Line FK251

Entwicklungs- & Vertriebs GmbHRTechnical datasheet | FK251 BlueLineInnovative – Powerful – Long-livingDue to its hydraulic properties, the FK251 BlueLine can be integrated to the building in axial inclination of 15° - 75° (pitched roof, flat roof and free standing). The s-power flat plate collector FK251 BlueLine can be used for domestic hot water, pool heating and for space heating. The main component of the FK251 BlueLine is the highly selective vacuum coated aluminum absorber. It ensures a high absorption (~ 95.0%) of solar radiation and simultaneously has a low emission (~ 5%) of heat radiation. A copper pipe harp is laser-welded onto the absorber. The to be heated heat carrier fluid flows through this pipe. The heat carrier fluid absorbs the heat from the absorber. The absorber unit (absorber and harp) is surrounded by a highly thermally-insulated sea-water resistant aluminum collector housing, which minimizes the heat losses from the collector. The collector is covered by a special Prismatic solar glass, which increases the performance of the collector through its prism effect (transmission> 90%). Through an easy to install mounting system, the collector can be easily and quickly installed on the building. The collector connection kit with insula-ted compression fittings allows for quick and safe connection of the collec-tors. Each collector is equipped with a thermowell for the collector sensor in order to detect the collector temperature accurately.2Product description:FK251 BlueLineA B C D EIHGFTechnical detailsA UV-resistant two-component adhesiveB Aluminium frame in Wave DesignC GlandD Prismatic solar glassE High selective coated absorber with register-pipeF Collector pipe insulationG Collector pipe connection 22 mmH Bottom plateI Insulation absorber unitEntwicklungs- & Vertriebs GmbHR3Product description:Technical dataFK251 BlueLineCollector typeGross area 2,51 m2Aperture area 2,39 m2Absorber area 2,31 m2Absorber material aluminiumAbsorber type harp/copperCoating BlueTec/eta plusDistance between the collectors 50 mmMeasurement:HeightWidthDepthAbsorber related values: Optical e?ciency % 79Heat loss coe?cient k1 W/(m2 x K2) 3,639 Heat loss coe?cient k2 W/(m2 x K2) 0,014Heat capacity kJ (m2 x K) 5,72 Weight 38 kgFluid content 1,7 lPermissible operating pressure 10 barMax. stagnation temperature 184 °CConnection Ø 22 mm Ø vertical2150 mm1170 mm 83 mm/ horizontal/ 1170 mm/ 2150 mm/ 83 mm201012158311702150Tested quality: The collector meets the requirements of the „Blue Angel“ RAL UZ tested 73 to EN 12975 and Solar Keymark and EN 12975 CE identification according to current EG DirectivesErrors and omissions excepted.
