FLAT SOLAR COLLECTOR

Maximum outputSolar thermal collectors use energy from the sun to generate heat for heating and hot water. This energy is free, environmentally friendly and reliable. The heart of flat-plate, air and evacuated-tube collectors is the absorber. It collects the energy in sunlight and converts it into heat. The more efficient the absorber, the greater the collector‘s output.

The absorber of Megasun flat collector is imported from Germany with its TiNOX absorbers: these products absorb 95% of incident sunlight. At the same time, depending on the absorber, they only lose around 4% through heat radiation. In this way, manufacturers of collectors can ensure the highest quality and maximum yield for their customers. Its highly selective absorber layers both to aluminium and copper substrates. Meg-asun flat collector therefore able to offer a wide range of high-quality products with TiNOX absorbers. TiNOX is characterised by outstanding absorption and emissivity rates. The highly selective blue coating guar-antees the customer the best possible collector performance.TiNOX has a highly selective, environmentally friendly coating, and with its reduced absorption rate is designed especially for regions with very high levels of sunlight. TiNOX comes in a wide range of colours and is therefore perfect for customers who wish to match it aestheti-cally with their building, especially, for example, in Mediterranean countries.TiNOX products are made in Germany in modern production lines in Bernburg.

TiNOX energy

is the premium product in the TiNOX product range: with its outstanding absorption and emissivity perfor-mance, the highly selective, blue absorber is the first choice for collector manufacturers who wish to guarantee their customers the highest output even when less sunlight is available.

is capable of absorbing 95% of incident solar radia-tion and converting it into heat. like an "energy trap," the highly selective blue TiNOX coating only loses approx. 4% of the captured solar energy as heat radiation.

TiNOX absorbers consist of a number of layers, carefully designed to work together. The substrate material is a highly infrared-reflective metal sheet that conducts heat well. A diffusion barrier is applied to the adhe-sive layer. This prevents metal atoms from entering the absorber layer at high temperatures and changing the optical properties. This is followed by the absorber layer consisting of a multilayer cermet structure. Final-ly, the top layer is an anti-reflective, protective layer made of fused quartz. This material is extremely hard and also scratch-resistant. The absorber is therefore very well protected from damage during handling. By minimising surface reflection, the absorption of solar radiation is further optimised.

All TiNOX absorbers are available with both copper and aluminium substrates. Both substrate materials have excellent thermal conductivity properties.

Solar absorption: α ~ 95 % Thermal emissivity: ε ~ 4 %

HEAT TRANSFER TECHNOLOGYHeat transfer technology through the collector in cloudy weather it can still absorb heat, it can work smoothly under the temperature of 60 degree, independent heat transfer pipe design without the water it also can resist over 230 degree, making the collector last for over 15 years or even more. The features of high pressure resistance, incorruptible and use indirect heat transfer system, frost resisting, no scaling

INTENSIVE COLLECTOR COREHigh selective blue coating made in Germany is designed with copper and aluminium material. It can absorb over 95% sunlight, low than 5% reflec-tion. Copper has higher feature of the heat trans-fer; increase the entire board thermal conductivi-ty of laser welding design, the efficiency can improve 5%

INTENSIVE TEMPERED GLASS COVERLow-iron crease tempered glass and black anti-reflection golden tempered glass is high transmittance, high intensive and impact resis-tance and can carried 700kg; black anti-reflec-tion golden tempered glass is good shaped and with high value

DOUBLE INSULATION DESIGNThe bottom of the collector core can resist high temperature and reflection, reducing energy loss when transferring, the whole foam of polyure-thane insulation can improve the collector’s intensive and efficiency of insulation, decrease the thickness
