Model FK251 -Blue Line

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 insulated compression fittings allows for quick and safe connection of the collectors. Each collector is equipped with a thermowell for the collector sensor in order to detect the collector temperature accurately.

• unique look due to wave-frame design in combination with solar prism glass
• highly selective coated aluminum absorber
• maximum heat transfer between the absorber and the copper grid by optimized laser welding technology
• ventilation system for fog-free operation
• intelligent ventilation system prevents the penetration of contaminants
• high precision as a result of a robot-controlled manufacturing production line
• long lifetime and environmental quality due to the use of recyclable materials
• easy transportation and installation on the roof due to the low total weight of only 38kg
• short installation time due to intelligent mounting design with slot-head screw-hammer system
• variable mounting options for nearly all roof types
• variable types of connection (up / diagonal)
• Solar Keymark certification
• 10 year warranty from date of manufacture
