The GeoSolar blue flat bed collectors are manufactured locally using the latest international best practices and technology to maximise the Q factor of the system.
The collector consists of 3 key elements:
1. The Absorber
2. The Frame
3. The Glass
The Absorber:
The absorber consist of Mirotherm strip material covering 22mm diameter copper header tubes. The main body of the absorber is made from Mirotherm fins. Microtherm consists of an aluminium- or copperstrip which has been anodised on both sides; then in a world-wide unique air-to-air process, a system of three layers is applied using the physical vapour deposition technique (PVD).
While an infrared reflecting layer ensures low thermal emission (5%), the metal oxide absorption and antireflection layers ensure highest solar absorption (95%) and offer resistance against outside agents.
Technical Data:
- 95% Absorbance
- 5% Emissivity
- 5 year functionality & weathering resistance warranty
The Frame:
The frame is made of aluminium extrusion which is anodised to 25 microns to provide a protective coating. This ergonomically designed frame uses high quality corner pieces for safety in handling and ease of construction.
The Glass:
The glass used is 4mm low-iron, SABS approved toughened glass. This glass is designed to withstand small stones and hail of up to 30mm in size.
Warranty:
- 5 year functionality & weathering resistance
- 10 year warranty with certified installation
